Cannabis how to grow from seed

Stages of Growing Cannabis

Cannabis, weed, marijuana, kush, ganja – whatever you want to call it, it’s now legal to own and grow in the state of Virginia. So what does this mean for those interested in growing it?

Growing Cannabis for the first time can be quite overwhelming. A quick Google search will lead you to hundreds of results with more information than you can ever sift through. There’s so much to learn – lighting, pH, soils, training methods, curing, and so much more. Where does one start?

It’s really easy to fall down the rabbit hole of information online. The sheer amount of information can almost hinder you when you’re first getting started. I think it’s easiest to just get started and learn as you go.

Starting with gaining a general understanding of the stages of growing Cannabis is a great place to begin before you try growing for the first time. It will help you have a decent idea of what to expect along the way.

How long does Cannabis take to grow?

How long Cannabis takes to grow can vary based on the variety of the plant and conditions it is grown in. On average, from seed to harvest, it takes anywhere from 10-32 weeks (about 3-8 months). It’s a quicker process if you start with a clone (rooted cutting) or an autoflower seed. The biggest variability in how long a marijuana plant takes to grow will happen in the vegetative stage—after the seedling phase and before flowering.

Stages of Growing Cannabis

Every plant begins with a seed. Cannabis seeds should be germinated just like any other seed. They can take anywhere between 3-10 days to germinate, although it can happen in as few as 24 hours or as long as 2 weeks. To germinate, you can place the seeds in a damp paper towel, which you should then place in a dark place, such as inside a drawer. Check on them after a few days to see if the primary root, called the radicle, has emerged. This will look like a little white “tail” coming out of the seed. Once germinated, move them to damp soil.

Alternatively, you can place the seeds directly in damp soil to germinate and grow, without having the trouble of moving them. For this method, I would recommend a seed starting mix. These are usually lighter and fluffier than traditional potting soil, which gives your fragile germinating seeds a start on the right foot. We carry Coast of Maine Sprout Island Blend Organic Seed Starter Mix. It has additional perlite that aerates the soil and helps prevent damping off. It also has mycorrhizae, worm castings, lobster meal, hen manure, and kelp to get your plants off to a healthy start.

2. Seedling Stage

Once your seed has germinated, it’s now time to move the germinated seed from its paper towel to a growing medium. If you started them in a seed starting mix, you will want to move them from the seed tray to a larger pot with a high-quality potting mix, such as the Coast of Maine Stonington Blend Grower’s Mix. This is a super soil, that works especially well for growing Cannabis. It contains mycorrhizae, kelp, alfalfa meal, fish bone meal, worm castings, perlite, manure, peat, coir, and lobster compost that feed your plant throughout the growing cycle, with no need to use additional nutrients.

Plants are considered seedlings for about 2-3 weeks after germination. During this time, the plant should be moved to a spot with direct sun, if growing outdoors. If growing indoors, set your grow lights to run for 16 hours a day.

3. Vegetative Stage

After the seedling stage, Cannabis plants move to a vegetative stage. This is the time when the plant focuses on leaf production. It will not produce flowers at all during this stage, as the plant needs to grow plenty of leaves to take up enough photons (sunlight) to create the necessary energy to produce large flowers. The vegetative stage can last anywhere from 3 to 16 weeks, depending on the variety.

During this stage, indoor plants need 16-18 hours of light per day, and outdoor plants need at least 6 hours of direct sunlight (“full sun”), plus several hours of indirect sunlight. They will also need plenty of Nitrogen during this point, as Nitrogen is the nutrient that promotes healthy leaf growth.

4. Flowering

The flowering stage is the last stage of the Cannabis plant life cycle. This is the time when your plant will stop putting as much energy into leaf growth and will instead focus that energy on creating the flowers (buds), which are used for medicinal and recreational purposes.

Cannabis is triggered to flower when the hours of light it receives are reduced. If you’re growing outdoors, you’re at the whim of the seasons and will have to wait until the sun starts to go down in fall for it to flower and then harvest. If you’re growing indoors, you get to play mother nature and can force your plant to flower at any point. When you’re ready for plants to start the flowering stage, change your lights to a 12/12 cycle ( 12 hours with the light on and 12 hours with it off ). You will see signs of flowering in 1-3 weeks . On average plants will be ready to harvest after 8-11 weeks of flowering.

5. Harvest

Your plant will be ready to be harvested once flowers are compact and the pistils turn orange/brown. These pistils look like “hairs” coming out of the flowers.

6. Drying

To dry your Cannabis, hang sections of the plant upside down in a dark, cool space, such as a closet. You want to aim for 55-65% humidity and 60-70°F in the spot that you’re drying your plants in. Prolonged periods of light, friction from handling, and humidity/dampness can degrade resin glands, so you will want to avoid all of these.

During the drying process, plants lose roughly 75% of water weight, which increases the cannabinoid to weight ratio. It also helps equalize moisture content, preserve cannabinoids, and shed chlorophyll.

Cannabis is ready to trim once the stem snaps when bent, typically after 3-7 days of drying.

7. Trimming

After your plant has dried, it’s time to trim! Trimming makes your fingers very sticky, so wear gloves if this is something you want to avoid. Simply trim off the larger leaves and stems. You can leave smaller sugar leaves if you’d like, as these still contain a good amount of cannabinoids and terpenes that provide the medicinal properties of Cannabis. It’s all personal preference of exactly how much you trim off. And you can save all the trimmings to make edibles, tinctures, salves, and more.

8. Curing

Curing is an essential part and the last stage in growing Cannabis. It helps the buds achieve full aroma. Curing is as simple as placing your freshly trimmed buds in a glass jar with a lid, like a mason jar. You’ll then want to place the jar in a cool, dark place, such as inside a drawer or in a cabinet.

During the first week of curing, you will want to “burp” your jars. This means you should open the containers once or twice a day for a couple minutes to allows moisture to escape and replenish the oxygen inside the container. After the first week, you only need to burp containers once every few days.

You should allow buds to cure for at least 2 weeks, but some people choose to cure for as long as 6 months. This helps stop the loss of moisture and to preserve flavors and aromas.

Cannabis seeds 101: How to grow marijuana from seed

Cannabis is grown from one of two sources: a seed or a clone. Seeds carry genetic information from two parent plants and can express many different combinations of traits: some from the mother, some from the father, and some traits from both.

In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.

If cannabis is legal in your state, you can buy seeds or clones from a local dispensary, or online through various seed banks.

Cannabis seeds vs. clones

For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.

Plants grown from seed can be more hearty as young plants when compared to clones, mainly because seeds have a strong taproot. You can plant seeds directly into an outdoor garden in early spring, even in cool, wet climates.

If growing outside, some growers prefer to germinate seeds inside because they are delicate in the beginning stages of growth. Indoors, you can give weed seedlings supplemental light to help them along, and then transplant them outside when big enough.

Most seeds that you will buy are regular seeds as described above, but here are a couple more types.

How weed seeds work

Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.

Once cannabis seeds are mature, the female plant begins to die, and seeds are either dropped to the ground where they grow into new cannabis plants next spring, or the seeds are harvested for processing into seed oil or food products, or stored so they can be sown in the ground later and become the next generation of plants.

To get the buds found in medical and recreational stores, female cannabis plants are grown in an environment without males—or the males are removed from the area before they release pollen—so the females don’t create seeds. Females can then focus their energies on producing buds and not seeds—this high-potency marijuana is traditionally known as “sinsemilla,” meaning “seedless.”

Some varieties of cannabis can produce male parts alongside female flowers on the same plant, especially if exposed to environmental stressors. These plants are known as hermaphrodites, and sometimes they can self-pollinate to create seeds.

Pros and cons of using cannabis seeds

If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.

Also, buying from a reputable breeder or seed bank will give you a sense of what a particular strain will look and smell like, how it will grow, and how much it will yield at harvest.

The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.

Sexing marijuana plants can be a time-consuming process, and if you don’t catch males, there is a risk that even one males can pollinate your entire crop, causing all of your female weed plants to produce seeds.

One way to avoid sexing plants is to buy feminized seeds (more below), which ensures every seed you plant will be a bud-producing female.

You can also minimize headaches and avoid the hassle of seed germination and sexing plants by starting with clones.

How weed clones work

Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”

Pros and cons of using cannabis clones

Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.

With cloning, you don’t have to get new seeds every time you want to grow another plant—you just take a cutting of the old plant—and you don’t have to germinate seeds or sex them out and get rid of the males.

One drawback of clones is they need to be taken during the vegetative stage of a plant—flower is too late—so if you have a small setup with only one light, it can be hard to keep clones alive while flowering other plants, because the two need different amounts of light.

Another drawback to clones is they can take on negative traits from the mother plant as well. If the mother has a disease, attracts pests, or grows weak branches, its clones will probably have the same issues.

Additionally, every long-time grower will tell you that clones degrade over time.

What are feminized cannabis seeds?

Feminized cannabis seeds will produce only female plants for getting buds, so there is no need to remove males or worry about female plants getting pollinated. Feminized seeds are produced by causing the monoecious condition in a female cannabis plant—the resulting seeds are nearly identical to the self-pollinated female parent, as only one set of genes is present.

This is sometimes referred to as “cloning by seed” and will not produce any male plants. This is achieved through several methods:

  • By spraying the plant with a solution of colloidal silver, a liquid containing tiny particles of silver
  • Through a method known as rodelization, in which a female plant pushed past maturity can pollinate another female
  • Spraying seeds with gibberellic acid, a hormone that triggers germination (this is much less common)

Most experienced or commercial growers will not use feminized seeds because they only contain one set of genes, and these should never be used for breeding purposes. However, a lot of beginning growers start with feminized seeds because they eliminate the worry of having to deal with male plants.

Top feminized cannabis strain families

A lot of classic weed strains that have been around for a while come in feminized form. Some popular fem seeds are:

  • OG Kush
  • Haze
  • Afghan
  • GSC (Cookies)
  • Skunk
  • Cheese
  • Gelato

What are autoflowering cannabis seeds?

Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.

Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.

However, a type of cannabis called Cannabis ruderalis, which developed in extreme northern conditions without much sunlight, will begin flowering once the plant reaches a certain age—they automatically start flowering regardless of the amount of light they receive, hence the name “autoflower.”

Pros and cons of growing autoflower

Because they grow and flower quicker, growers can fit in multiple autoflower cannabis harvests into the span of one regular harvest.

Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.

Also, autoflower plants are small—perfect for closet grows or any small grow, or growing outdoors where you don’t want your neighbors to see what you’re up to.

A couple big drawbacks, though: Autoflower strains are known for being less potent. Also, because they are small in stature, they usually don’t produce big yields.

However, potency in autoflowering varieties has increased significantly since their initial introduction, with some breeders crossbreeding the low-THC ruderalis with other more potent varieties.

Tips for growing autoflower marijuana seeds

Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.

Climate considerations

Many marijuana growers start autoflowers early in the season, and at a different time than a regular crop, so keep the season and climate in mind when growing and harvesting—your plants still need warmth to grow, and rain can give them bud rot. Consider growing in a greenhouse to protect them.

Training plants

Because training happens during vegetative growth, for autoflowering plants, this period could be as short as a few weeks, which means time is limited. Try topping your autoflowers after they have three nodes, and stop once they begin to flower. You will want to prune them lightly.

Go easy on nutrients

Autoflowers don’t need lots of nutrients because they’re small and don’t spend much time in the vegetative cycle. They won’t need as much veg nutrients—such as nitrogen—but will need more bloom nutrients.

What are high-CBD cannabis seeds?

CBD, or cannabidiol, is one of the chemical components—known collectively as cannabinoids—found in the cannabis plant. Over the years, humans have selected plants for high-THC content, making cannabis with high levels of CBD rare. The genetic pathways through which THC is synthesized by the plant are different than those for CBD production.

Cannabis used for hemp production has been selected for other traits, including a low THC content, so as to comply with the 2018 Farm Bill. Consequently, many varieties of hemp produce significant quantities of CBD.

As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).

Seeds for these varieties are now widely available online and through dispensaries. It should be noted, however, that any plant grown from these seeds is not guaranteed to produce high levels of CBD, as it takes many years to create a seed line that produces consistent results. A grower looking to produce cannabis with a certain THC to CBD ratio will need to grow from a tested and proven clone or seed.

How to germinate marijuana seeds

Germination is the process in which a seed sprouts and begins to grow into a new plant. Also referred to as “popping,” germination is the very first step in starting your weed grow.

Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.

Cannabis seeds require three things to germinate: water, heat, and air. There are many methods to germinate seeds, but for the most common and simplest method, you will need:

  • Two clean plates
  • Four paper towels
  • Seeds
  • Distilled water

Step 1

Take four sheets of paper towels and soak them with distilled water. The towels should be soaked but shouldn’t have excess water running off.

Step 2

Take two of the paper towels and place them on a plate. Then, place the marijuana seeds at least an inch apart from each other and cover them with the remaining two water-soaked paper towels.

Step 3

To create a dark, protected space, take another plate and flip it over to cover the seeds, like a dome.

Step 4

Make sure the area the seeds are in is warm, somewhere between 70-85°F.

After completing these steps, it’s time to wait. Check the paper towels once a day to make sure they’re still saturated, and if they are losing moisture, apply more water to keep the seeds happy.

Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.

A seed has germinated once the seed splits and a single sprout appears. The sprout is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination.

It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.

Transplanting germinated cannabis seeds

Once you see the taproot, it’s time to transfer your germinated seed into its growing medium, such as soil.

  • Fill a 4-inch or one-gallon pot with loose, airy potting soil
  • Water the soil before you put the seed in; it should be wet but not drenched
  • Poke a hole in the soil with a pen or pencil—the rule of thumb is: make the hole twice as deep as the seed is wide
  • Using a pair of tweezers, gently place the seed in the hole with the taproot facing down
  • Lightly cover it with soil

Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.

Within a week or so you should see a seedling begin to grow from the soil.

Germinating cannabis seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.

This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones or for breeding if you want to create a seed bank of your own.

How to sex a pot plant

Check out Johanna’s full video series on how to grow weed on Leafly’s YouTube .

As we’ve mentioned, cannabis is a dioecious plant, meaning male and female reproductive organs appear on different plants.

Because only female cannabis plants produce buds and you want them to focus all their energy on producing buds and not seeds, it’s important to identify and get rid of male weed plants so they don’t pollinate females. If females are pollinated, it will give you buds filled with seeds, making your weed harsh and unpleasant.

Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.

As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.

If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.

Cannabis plant sex organs appear on nodes, the points where branches grow off from the main stalk.

Males will have round balls—these will develop into pollen sacs, which will release pollen into the air when mature.

Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.

Pre-flowers can initially be extremely small and hard to identify with the naked eye, but you can use a magnifying glass to get a better look.

Can I grow a seed I found in a bag of weed?

Finding a cannabis seed in your stash is not ideal, but we’ve all been there before. Although much less common than it once was, it still happens. Sometimes you’ll notice one when grinding down some flower, or you’ll see one pop, spark, and crackle from the heat of a lit bowl.

These are referred to as “bagseeds” and whether or not you can grow one will depend on where it came from.

Is a bagseed good or bad?

Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.

Seeds can also form in plants with genetic disorders or instability, like hermaphrodites—plants that develop both male and female reproductive parts. Generally, stress and genetic disorders are viewed as bad, so temper expectations with any plant you start from a bagseed.

But sometimes you get lucky and find a mature seed in some really nice herb. Strains like the legendary Chemdog wouldn’t be possible without adventurous smokers planting and proliferating the seeds they found in a bag of kind bud.

So don’t discount bud because it has a seed or two in it. While not ideal, it could be the origins of the next great weed strain.

Ask yourself a few questions to decide if it’s worth the time and energy to grow the seed.

Was the seed found in good weed?

If you don’t like the flavor, effects, or even the look of the bud, then it’s probably not worth growing.

Are you ready to grow?

Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.

Is the seed viable?

For a seed to be viable, it must be mature enough to have a completely formed genetic blueprint, and it must be strong enough to germinate and pop through its hard casing and sprout its crucial taproot.

There are a few indicators that will give you a sense of whether the seed is worth germinating.

  • Tiger stripes—dark stripes on the seed which resemble veins on a leaf are generally good
  • Solid shell—a seed should be able to withstand a little pressure when pinched between your fingers; if it crumbles or cracks, it’s no good

Immature seeds tend to be light in color and have a soft outer shell.

In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.

You might also find a mature seed that has been physically damaged through poor handling, like rough trimming. In those cases, it probably isn’t worth the effort to try and germinate the seed.

But if the seed you found looks decent, you might as well germinate it and see what sprouts.

Time to germinate

Viable or not, there’s only one sure way to find out if a bagseed will grow. If you’re simply curious to learn and not as concerned with the overall outcome, you can plant a couple of bagseeds outside and see what happens.

If you’re ready for a more serious approach, make sure you have the space for a proper garden and pop the seeds to see what fruit they bear.

Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.

Remember, once a seed germinates, the real work begins. Sexing, selecting, vegetative growth, flowering, and the eventual harvest all lie ahead.

How to buy cannabis seeds

Cannabis seeds can be found on numerous online seed banks, but note that it is illegal to bring seeds into the US and Customs will seize any cannabis seeds that they find in packages or on a person. In legal and medical states, you may purchase seeds at a dispensary.

How to Grow Marijuana from Seed

If you’re in a location where cannabis (another term for marijuana; short for the plant cannabis sativa) is illegal, growing it is probably illegal too. Bringing in seeds or cuttings to your location can very well be a felony, and reputable sellers won’t ship to you.

You can probably purchase and grow hemp seeds and plants, which have a negligible amount of THC, but these plants won’t produce the psychoactive effects of plants that contain higher levels of THC. Check with your seller to be certain you’re getting what you think you’re purchasing. If you buy seeds for CBD-only hemp plants by mistake, you can end up being very disappointed post-harvest.

How to acquire seeds or cuttings

You can usually find cannabis seeds for sale at most dispensaries in areas where growing cannabis for personal use is legal. You may also find growers who sell cuttings/clones. You can expect to pay $50 to $100 for a pack of ten seeds. When shopping for seeds or cuttings, read the labels and any other information the manufacturer provides on its website or in its catalog to make sure you’re getting the right seeds or cuttings (the strain) for the plants you want to grow.

One way to get your mitts on some seeds is to collect seeds when you find them in flowers you purchased, or get some from friends if they’re collecting.

  • Feminized seeds: Nearly all seeds sold by reputable companies are feminized, but make sure they are. These seeds are specially treated to grow into female plants.
  • Auto-flowering or photoperiod: Auto-flowering plants are easier, because they enter the flower stage after a certain number of weeks regardless of the light/dark cycle. If you’re a beginner, seriously consider going with auto-flowering plants.
  • Genetic background: If seeds are from a well-established strain, such as O.G. Kush, Bubble Gum, or a cross-breed, the genetic background should be stated.
  • Blend: The blend represents the percentage of the three species — sativa, indica, and ruderalis. All auto-flower strains contain some percentage of ruderalis, which is responsible for the auto-flowering nature of the plant.
  • Yield indoors: The number of grams of bud per square meter of plant when grown indoors.
  • Yield outdoors: The number of grams of bud per plant (after drying) when grown outdoors.
  • Plant height indoors: Shorter than when grown outdoors.
  • Plant height outdoors: Taller than when grown indoors.
  • Time to harvest: Approximate number of weeks after germination the flower should be ready to harvest.
  • Potency: Percentages of CBD and THC.
  • Effect: The type of experience you can expect when consuming product from the plant.

Know the laws about buying cannabis

  • In some European countries, laws prohibit growing cannabis, but seed is legal, which is quite confusing. You’re allowed to buy and eat cannabis seeds because they’re non-psychotropic, but you can’t buy them to grow cannabis. Other countries in Europe, such as Germany, have their own seed laws.
  • In Canada, where cannabis is federally legal, seeds can be shipped across provincial lines.
  • In the U.S., in some states in which cannabis is legal, you can purchase seeds from some dispensaries or other locations to grow plants as long as you keep them in the state. Other states may bar selling to non-licensed growers. Shipping or transporting seeds across state or international borders is illegal, although a few reputable online seed stores ship to individuals with success.

Cuttings are typically treated in a similar manner as seeds in legalized locations. They may be available from some dispensaries or outlets for pick up or delivery with a fee. They’re prohibited from crossing U.S. state lines or international borders. You can buy individual plants and mix and match strains. Prices vary and are often determined by plant size.

Buy cuttings (clones) only from a reputable source who understands proper back-crossing of strains for stability. Back-crossing involves pollinating a plant with one of its parent plants to promote sexual stability, so that when you have a female it won’t hermaphrodite into a male during flowering.

Both seeds and clones are often able to be purchased from commercial locations already in your state.

In the U.S., transporting any part of the cannabis plant over state lines is illegal. This applies to seeds and clones and, technically, even to tissue samples.

How to germinate cannabis seeds

Germinating seeds requires a dark environment that is around 70 degrees. There are many ways to germinate seeds (in soil, in a wet paper towel, in starter plugs) You can also sow them directly into soil in a garden or container, as long as the soil is light and fluffy, so the roots can easily grow down and the stalk can break through the soil. Plant the seeds about 1/4- to 1/2-inch deep and cover them loosely with soil.

Most importantly, seeds need a moist environment; they won’t germinate if they get too dry. You can use a heat mat to increase the success of germination in colder climates.

How to transplant marijuana plants

When transplanting any plant, whether it started from seed or a clone, handle it gently, being very careful not to damage the roots. Center the plant in the pot, and plant it deep enough to cover the root ball completely in soil. If the plant is root bound, you can gently tease the roots apart to encourage outward growth.

Pack your soil or other grow medium down around the roots well enough to support the plant while new roots grow, but not so tight that the soil restricts outward root growth. Water the soil around the roots.

Atomic northern lights seeds

Atomic Northern Lights

Atomic Northern Lights effects are mostly energizing.

Atomic Northern Lights potency is higher THC than average.

Atomic Northern Lights has a history of world travel. In the 1980s, Afghani indica seeds were brought to the U.S. and bred with Thai Haze. The result was known as Northern Lights, a three-time Cannabis Cup winner during its stay in Holland, where it was developed and stabilized by Sensi. Northern Lights then went to Canada and Dr. Atomic Seeds recrossed it with its own distant relatives. The result was an indica-dominant strain with fast flowering times (approximately 8 weeks), short stocky plants, and a mind/body sensation with an uplifting effect. Atomic Northern Lights’ scent has been described as pungent and the strain has a sweet flavor.

Atomic Northern Lights’ scent has been described as pungent and the strain has a sweet flavor.

Atomic Northern Lights Is ‘A Bomb’ Strain

Atomic Northern Lights has a history that stems all the way back to the early 80’s. It all started when some Afghani seeds landed in the northwest of the United States and were mixed with some Thai Haze. This strain was stabilized indoors by Sensi Seeds and became what we know today as Northern Lights. This strain went untouched and went on to win three Cannabis Cups in its tour in Europe before a man who went by the name Dr. Atomic, got his hands on it and decided to make some history of his own.

Not Your Average Northern Lights, It’s Atomic…

The legend is that Dr. Atomic brought the foreign Northern Lights back to Canada where he then back-crossed it with some of its distant North American relatives. The resulting plant is an Indica-dominant plant with about 15-20% Sativa components that goes by Atomic Northern Lights. The Atomic Northern Lights strain tends to grow short and fast, while consistently producing heavy yields.

The Atomic Northern Lights strain has an incredibly pungent haze smell with a sweet and sugary undertone. The taste was surprisingly fruity upon inhale, but the exhale was very similar to the smell; very hazy with earthy undertones. It was interesting because when I vaporized the herb, only the fruity flavors were detectable. I only got the mustier, haze taste when I ripped a bowl out of the Toro.

“The haze stench produced by the Atomic Northern Lights strain almost burns your nostrils when you stick your nose in the jar.”

The effects were very enjoyable as well, but were definitely delayed. I would have to consider this marijuana strain a creeper. After the first hit, I felt almost light-headed and very buzzed. I could feel my pupils begin to dilate and my mind begin to clear. However, within just five minutes my legs were kicked up on the ottoman and I could hardly feel them.

Let’s just say AtomicNorthern Lights is full-bodied. The spacey effects left me feelings untouchable, which makes sense why this strain is popular among patients looking to cope with anxiety or chronic stress disorders like PTSD. Not to mention the Atomic Northern Lights strain frequently lab tests at high THC percentages; this has been proven to provide a boost in appetite for patients dealing with stomach issues and/or eating disorders without any harmful side effects.

The smoke from each hit was very thick, creating an inescapable cough after each hit. I would consider this batch extremely potent, as the high lingered for about two and a half hours in my mind and a little bit longer in my body. I actually packed a second bowl and forgot about it for about a half-hour because I got distracted; always a good sign of strong medicine. There is no doubt that Atomic Northern Lights definitely deserves a spot on the bucket list of all Indica strain connoisseurs.

Oregon pineapple seeds

Lemon Pineapple Seeds

Lemon Pineapple is a beautiful strain constructed by Lemon Tree Range and has now finally been perfected after many years of selecting just the right varietals to make it what it needed to be. Lemon Pineapple is a powerful sativa dominant strain consisting of a heavy pineapple aroma with a side of lemon and apple. Lemon Pineapple is best grown outdoors because of its height and length, but can also be grown just as successfully inside if you top it early or have the height for her.

Every (1) packet comes with 10 seeds for $29.99.

Description

Lemon Pineapple is bred for an unmistakable lemon taste and smell. It is the lemoniest of the crosses being bred, and since users like the lemon, expect the strain to become more lemon and less kush/skunk/diesel, increasing its terpene profile of limonene while phasing out the taste of kush. Lemon Pineapple may appear to be a paler green than other strains and it may even look yellow. Buds are sticky and the plant has white or orange trichomes, the plant’s appendages.

Medical users like the sedative effect of Lemon Pineapple that helps with appetite and stress. Other uses include bipolar disorder, depression, PTSD, and OCD. People undergoing chemotherapy may appreciate the strain for relieving nausea and increasing appetite.

The plant will grow short to medium high. It should have long colas, and flower in an average of 70 days with a good yield.

Jeff (verified owner) – November 11, 2021

Fast shipping. All 10 seeds sprouted within 24 hrs. If the genetics are half as good as the price, speed and seed viability then I will be in for a real treat. Will update once plants are harvested.

Franklin Suville – December 28, 2020

Thick stuff, pretty remarkable scent. Very happy customer.

Wendy Anderson – December 28, 2020

Greg Hollison – December 28, 2020

Pulled about 4lbs per plant (20gallon) on all of mine this past fall. Just, wow. What an amazing strain, well done Oregon. Well done

Jeff Ogilvy – December 28, 2020

True Lemon taste and smell. Thanks again guys, always killer stuff.

wanted1 – November 14, 2020

I’ve been sky-rewed by several “foreign” sellers, but these guys are in business to STAY in business- straight up & bona-fide yes sir! Fast to ship a very fine product and I’ve yet to find a single bean that failed. Did I mention that their product arrives within 3 / 4 days usually? I did? OK, I’m done then.

Basic / Breeders Info

Oregon Green Seeds Willamette Valley Pineapple is a THC dominant variety and is/was never available as feminized seeds.

Oregon Green Seeds Willamette Valley Pineapple Description

Sativa dominant in effect with a more indica growth habit. The Willamette Valley Pineapple is an easy grower that’s resistant to most things that plague many other cannabis cultivars.

The Pineapple is always on the ‘top 5 requests’ list that I ask from my patients each year … because its a GREAT daytime medicine that helps with pain, energy, and mood. Its a mainstay in most ‘grower’ gardens because it holds its own against the most elite of strains, and it can be counted on to bring in a bountiful harvest of beautiful bud before the end of September and the onset of non-stop rain here in northern Oregon.

Despite it producing sizeable buds of medium/high density, it is surprisingly resistant to powdery mildew and mold.

Willamette Valley Pineapple grows into a well-structured/well-branched plant with bright green leaves. Outdoors the branches will grow strong and they can hold the weight of its ‘bigger than golf ball’ sized flowers.

Think of Willamette Valley Pineapple as the OGS version of the well-known Pineapple Express (G13 Labs) — but Willamette Valley Pineapple has the ability to grow larger, and produce individuals of noticeably higher potency while retaining the short flowering period and ease of growth that Pineapple Express is noted for.

Flowering period: ~ 52-58 days
Harvest outdoor beginning 3rd week Sept. (northern Oregon)

Height: 4-7 feet
Yield: medium high to high
Potency: 8 on a scale of 1-10

Attitude Seeds Review 2022

Read up on Attitude Seeds’ mixed reputation for quality, product selection, customer service, free seeds, and discounts.

Attitude Seeds bills itself as “the world’s largest cannabis seeds superstore”, and although it’s impossible to access the exact numbers to confirm it, the Attitude seed bank does seem to offer an incredibly large variety of merchandise.

One quick look at their website confirms it – Attitude Seeds stocks seeds from almost every major breeder as well as apparel and accessories. One thing that they don’t seem to sell is growing materials and equipment (read on for the legal reason behind that), so you’ll have to look elsewhere for those things. This massive seed reseller based in the United Kingdom sources seeds from all over the world and ships them that far, too.

Attitude Seed Company History

Unfortunately, very little information is available regarding the history and origin of Attitude Seeds. Many seed banks have a page dedicated to telling the story of how they came to be in this business, but this one doesn’t seem to. For now it will remain a mystery!

Attitude Seeds Reputation

Attitude Seeds is a mixed bag when it comes to reputation. There are some customers who swear by them and others who have had one too many bad experiences and swear them off completely. When you search online, you’ll find someone praising the company in one Attitude seeds review and another customer warning others away in a different review, so who can you trust? Why is there such a sharp divide in opinion?

Well, a lot of the variation in customer satisfaction is likely due to the varying quality of the products that they stock at the Attitude Seed Bank. Since they sell just about everything, there are bound to be some bad products in the bunch. If you don’t do your research first and find out which strains are worth your while and which are total duds, it can be hard to know what exactly you’re getting when you buy from Attitude Seeds. This likely accounts for the wild variances in Attitude Seed Bank reviews.

Attitude Seed Selection

As of 2022, Attitude Seed Bank offers literally thousands of different strains from a huge variety of breeders, including quite a few Cannabis Cup winners. They do sell all types of seeds – those from reputable breeders and those from relatively-unknown brands. It’s not that all of the lesser-known brands offer bad products, but you do need to be careful when buying from seed breeders without an established good reputation.

Here’s a list of just some of the brands that Attitude Seed Bank stocks: Ace Seeds, Barney’s Farm, Big Buddha, DNA Genetics, Dinafem, Dutch Passion, Nirvana Seeds, Paradise Seeds, Royal Queen Seeds, Sensi Seeds, Serious Seeds, G13 Labs, Delicious Seeds, CBD Crew, And so many more! The complete list is quite extensive and rest assured, you could spend days just browsing through all the strains that are available on this website.

Product Quality

With so many different strains available from all different breeders, it’s impossible to judge overall quality. This will vary wildly from brand to brand. If you have a trusted breeder that you love, you should find that buying their seeds through Attitude Seed Bank gives you the quality of product that you’re used to.

However, Attitude Seeds seems to have the attitude that more seeds is always better, so they don’t really curate their selection with any type of quality-control standards. Rather than sorting the wheat from the chaff and offering only the best, most high-quality seeds in their shop, Attitude sells anything that they can get their hands on and leaves it to the buyers to sort out which seeds are high quality and which will be disappointing. They sell everything from top-of-the-line luxury seeds to bottom-of -the-barrel bargain bin beans. Because of this, it’s not recommended to buy from Attitude Seeds without a clear knowledge of what you’re getting. Sure, it may be fun at first to browse their pages upon pages of different strains and add random things to your basket, but if you don’t know anything about the brands that you’re buying from, you may wind up with a lot of duds.

You can find great stuff at Attitude Seeds if you know where to look, but if you’re just going in blind, you’re going to be overwhelmed and likely buy some bad seeds. It’s a good idea to always go in with a shopping list of strains from brands you trust and search specifically for those brands. If you’re not sure which brands are good, check out our reviews of the best seed banks, all of which have been updated for 2022.

Customer Service

Customer service at the Attitude Seed Bank can be reached in a variety of ways. You can call them up at 01473 724 698 for UK customers, or use either of their two international phone lines at 0044 1473 724 698 or 011 44 1473 724 698. You can also send them an email at [email protected] or [email protected], depending on your reason for contact. Or, instead of direct email, you could fill out the contact form on their Contact Us page with your name, your email address, and a description of the issue that you are experiencing. If none of those options work for you, you can even send them snail mail to their physical address (available on their contact page).

All times above are listed in BST. This is also when you can expect them to respond to your email or contact form submission. They aim to respond to all queries promptly within 24 business hours. The customer service team is generally friendly and helpful, though when it comes to certain issues with seed quality and germination issues, there is not much that they can do to help you. They will pretty much only be able to assist with issues like these if your seeds were damaged in transit and you can prove as much with photos. If you have an issue like low germination rates or bad genetics, they will more than likely tell you that it’s a problem for the seed breeder and they won’t be able to do anything for you. This is why customers are warned to be careful about which breeders they buy from in the Attitude Seeds shop! Attitude Seed Bank takes very little responsibility for the quality of the products they stock, so buyer beware.

One other thing is that Attitude Seed Bank officially sells cannabis seeds only as souvenirs in 2022 and fully expects customers who buy their products to keep them in storage in their ungerminated state in case of law changes in the future. Because of this, refuse to been seen as promoting germination in any way (such as by listing germination rates on their product pages or by selling additional growing supplies). This also means that they can’t answer your questions about germination issues directly. If you contact customer service asking for germination or cultivation advice, you may find that the email or phone call goes unanswered or totally ignored.

Attitude Seeds Shopping Experience

The shopping experience at Attitude Seed Bank can be quite overwhelming. As of 2022, they have over 2,000 different strains in stock from tons of different breeders. This is no place for a beginner who wants to do a bit of casual seed-browsing. When you shop at Attitude Seed Bank, it’s best to have a very clear idea of what you’re looking for before you dive in – or at least know which breeders you want to buy from.

The sheer selection isn’t the only thing that makes the website shopping experience feel a bit overwhelming, however. As soon as you arrive on the homepage, you’re greeted by an onslaught of bright colors, scrolling information bars, flashing promotional boxes, pictures, countdowns, and other doodads that strain both your eyes and your computer’s processing power. There is a lot going on on the Attitude Seed Bank landing page, to say the least.

Even once you get past the homepage, though, the sensory overload doesn’t let up. There are several scrolling informational banners that follow you wherever you go on the site, and on each product page there are more pictures and colored tags with complicated fonts. Not to mention the fact that at the bottom of every single page is a huge box with a lengthy list of each breeder they stock at Attitude Seed Bank.

Every page is extremely cluttered and feels like it’s stuffed way too full of information and images. Browsing around this website casually seems like a real nightmare. It’s recommended for new customers to simply stick to the search bar.

Attitude Seeds Promotions, Discount Codes, and Free Seeds

The Attitude Seed Bank does offer promotions and free seeds, which definitely sets it apart from many of its competitors. However, as mentioned above, its website is so overcrowded that it may take a moment (and a deep breath) to collect yourself and find the promotions in order to take advantage of them.

Once your eyes settle down from the visual overload, you’ll note that there is a Promotions section at the top of the website. There, you’ll find various seed promotions depending on what brands you throw in your cart. In addition to this, Attitude Seeds gives away free seeds with each order.

For promotions on an easy-to-navigate massive selection of seeds that ship worldwide, most savvy cannabis consumers prefer MSNL’s Special Offers and Promotions page.

Cannabis seeds too cold

Jorge’s Cannabis Encyclopedia: Seed Germination

Cannabis seeds need only water, heat, and air to break dormancy and germinate; they do not need extra hormones, fertilizers, or additives. Seeds sprout without light in a range of temperatures. Strong, viable, properly nurtured seeds germinate in 2 to 7 days. At germination, the outside protective shell of the seed splits, and a tiny, white sprout (radicle) pops out. This sprout is the root, or taproot. Cotyledon, or seed, leaves emerge on a stem from within the shell as they push upward in search of light.

Break dormancy: Put newly harvested seeds in the refrigerator for a week or two to simulate winter. Remove and germinate. Seeds will germinate more uniformly because they all come out of dormancy at the same time.

Timeline for Germinating Most Seeds:

At 36 to 96 hours – Water is absorbed, root tip (radicle) pops through outer shell and is visible.
At 10 to 14 days – First roots and root hairs become visible.
At 21 to 30 days – At least half of seeds are rooted by day 21. Seeds not rooted by day 30 will probably grow slowly.

Once seeds are rooted, cell growth accelerates; stem, foliage, and roots develop quickly. Seedlings develop into full vegetative growth within 4 to 6 weeks of germination.

Seeds are Prompted to Germinate By:

water
temperature
air (oxygen)

Water: Soaking seeds in water allows moisture to penetrate the protective seed shell within minutes. Once inside, moisture continues to wick in to activate the dominant hormones. In a few days, hormones activate and send enough signals to pro- duce an initial root tip. The white radicle (rootlet) emerges to bring a new plant into the world. Once a seed is moist, it must receive a constant flow of moisture to transport nutrients, hormones, and water so that it can carry on life processes. Some seeds need lots of moisture to wash out the dormancy hormones in the seed coat, and if they do not get enough moisture, they do not germinate. Conversely, too much water deprives the seed of oxygen, reducing its quality or destroying it. If fragile germinated seeds are allowed to suffer moisture stress now, seedling growth will be stunted. Soaking most seeds in water for 12 to 24 hours is all they need to initiate germination. All the nourishment for a seed’s initial growth requirement is pulled from the fleshy cotyledons, or seed leaves. Water seedlings with low-EC (electrical conductivity) household tap water during the first week or two of life. Supple- mental nutrients are unnecessary and if applied in excess can disrupt internal seed chemistry. Some gardeners prefer to germinate seeds using distilled or purified water that contains virtually no dissolved solids.

Temperature: Overall, cannabis seeds germinate in temperatures from 70°F–90°F (21°C–32°C) and grow best at 78°F (26°C). Temperatures below 70°F (21°C) and above 90°F (32°C) impair germination. Low temperatures delay germination. High temperatures upset seed chemistry causing poor germination. Seeds germinate best under the native conditions and temperature ranges where they were grown.

Air & Oxygen: Sow seeds twice as deep as the width of the seed. For example, 0.125-inch (3 mm) seeds should be planted 0.25 inches (6 mm) deep. Adequate oxygen is un- available for seeds planted too deeply, and tender seedlings have insufficient stored energy to drive through deep layers of soil or crusty hard soil when sprouting.

Agricultural Astrology — Planting by the Moon

Ancient Babylonians and Egyptians planted and harvested based on moon phases in relation to geographic location. The premise is that plants grow better when planted during the appropriate moon phase.

Moon phases cause ocean tides to rise and fall. They also affect the rise and fall of moisture in soil and fluids inside plants. The moon phase influence is said to be the same indoors, outdoors, and in greenhouse-grown cannabis.

Cannabis gardeners who plant by the moon report faster-sprouting seeds that grow into vigorous plants. However, scientific evidence is lacking in regard to cannabis and other plants’ relationship with agricultural astrology.

Seeds need oxygen from the air to germinate. Growing mediums that are too moist (soggy) will cut off oxygen supplies and the seeds will literally drown. Cannabis seeds germinate best when moisture is between 60 and 70 percent.

The effect of cold on cannabis plants

Cannabis as a plant species grows wild in many places of our planet Earth. As a result, we can find a great diversity of cannabis genetics worldwide. Across the different regions where these plants are found, there are significant environmental and geographical differences in altitude, latitude, temperatures, humidity, photoperiod, etc.

Cold, warm and hot areas of the planet

In countries closer to the tropics where cold weather is rarely experienced, it’s possible to cultivate cannabis throughout the whole year, and the Sativa or NLD (Narrow Leaf Drug) varieties that are native to this tropical region are adapted to cope with a relatively stable climate without great variations in temperature or photoperiod. As we move further away from the equator, to countries such as Pakistan, Lebanon, Afghanistan, India, Russia, China etc, weather conditions become more diverse, with clearly defined seasons and as a result, the period in which it is possible to cultivate cannabis is shortened according to latitude. The plants native to these areas are known as Indica or WLD (Wide Leaf Drug) varieties and they are well equipped to deal with wide variations in climactic conditions affecting temperature, humidity and also the effect of the changing photoperiod on plant morphology and life cycle.

When growing indoors, these adverse environmental conditions are not such an issue, we can easily recreate the optimal atmospheric conditions needed for healthy plant growth within a small indoor garden, whether a grow tent or a small grow room. Modern indoor technology allows us to completely control all the parameters – the hours of light, the ventilation, temperature, humidity, etc, and create the perfect environment to grow cannabis throughout the year.

Sea of green in winter

Possible problems can arise indoors during winter if the air intake to the grow room is drawing directly from the exterior. When the lights are working, this works very well to counter-act the heat produced and cool the grow space to the ideal daytime temperature of 24-26ºC; however, at night when the lights are switched off and it gets cold outside we can encounter problems as temperatures inside fall well below the comfortable night time level of 20-22ºC. An easy way of avoiding this issue is to install a temperature controller, a device that allows us to regulate the air intake and keep the ambient temperature well within the optimal parameters, thus averting any difficulties caused by excessive variations in temperature.

How does the cold affect cannabis plants?

Cannabis varieties react differently to cold, although below a median temperature of 12ºC they are universally at risk of death. As with water, which at higher temperature contains a lower concentration of dissolved oxygen, once the air cools to below 18-20ºC the plant’s metabolism will slow down gradually and hinder or halt development.

Cannabis plant battling tough winter conditions

As the plant’s metabolism slows down everything becomes much less active. The bio-chemical and enzymatic processes required for healthy growth cannot take place and vegetative vigour disappears leaving plants small and weak. The root system cannot function as it should, rendering it unable to absorb adequate nutrition. This will have an obvious negative impact on yields, leading to very small buds and vastly reduced production.

As previously mentioned, low temperatures will detrimentally affect the root system and the uptake of nutrients, particularly in the case of magnesium. This micro-nutrient is vital for the proper development of the cannabis plant and if the substrate is colder than 18ºC then this element is most likely not being absorbed by the plant.

Healthy cannabis plants in flower, protected from low temperatures

If, in addition to a low cultivation temperature, the growing medium is over-irrigated or water-logged, then the plant will be completely unable to take up magnesium, leading to visible deficiencies in the larger leaves, which even the application of magnesium in every watering will be unable to solve.

As we can see, controlling the temperature of our grow is integral to a successful cannabis harvest and there are various options available to help us do this, adaptable to each grower’s needs based on dimensions, ambient temperature, lights used etc.

How to avoid low temperatures indoors

The most common solution to heating the grow space is to use an electric heater; however, this has it’s disadvantages, mainly it’s high consumption of electricity as usually devices of 1500-2000w are employed, but there are other problems with this type of heater, for example the drying effect it has on the air, requiring some degree of humidification, and the direct, non-radiant nature of heat distribution which makes it difficult to maintain the even, stable temperature that plants enjoy throughout the whole grow space.

Turbular heater on the growing tray

Another option to consider is a portable oil-filled radiator, similar to the popular wall-mounted electric heaters, but with wheels for mobility and convenience. These radiators are a good option but not perfect; their size makes them difficult to conveniently use in a regular grow tent and besides, the consumption is far from negligible at over 1000w. While it may be possible to rig something up if the heater won’t fit into the tent, using a large, well-sealed cardboard box and a small fan to direct warm air from the heater into the tent, it’s far from a permanent, practical solution to the demands of a small grow space.

Of all the options available on the market today, the most simple and effective is to use a small sized tubular electric heater. This device only consumes a few watts of power, making it a very good option for those grow boxes with minimum floorspace of 0.60m2.

Tubular heater of 1.22m

The 90w heater, 61cm long or its other version of 122cm and 135W both have IP55 rating, a kite-mark indicating resistance to splashes and dust ingress, making them ideal for using in a greenhouse or indoors.

For the best results, we can place the heater on the floor of the grow tent, installing legs with adjustable height to raise the grow tray, or as a rudimentary method, use some empty plant pots under the tray to raise the plants off the ground and allow air to flow around the base.

Tubular heater at the base of the growing box

As the warm air is less dense than the cold air, it will rise and pass between plants until settling at the top of the cabinet. In order to not lose this heat and keep temperatures constant it’s necessary to halt the air extraction-fan for a few hours. We can easily do this with the help of a temperature controller programmed to switch the fan off when it reaches a certain temperature, and then activate it again when it drops below that point.

Situating the heater underneath the tray has the added advantage of warming the substrate and root system, encouraging healthy growth and permitting greater vegetative vigour, in turn leading to a bigger and better quality harvest of buds.

Radiating cables for indoors

Another highly convenient option to consider if for some reason we can’t install a tubular heater is the use of heating cables of the type normally used in propagators for germination of rooting cuttings or in terrariums to acclimate reptiles to their artificial environment.

Long heating cord for several plant pots

These radiant cables are available in different sizes, enabling us to find different options to suit our growing needs. Being pliable, we can loop them around the bottom of the plant pots so that the entire root system is warmed and can expand with ease. For large pots, it’s recommended to employ a cable for each pot, or use it for two or three pots in the case of a smaller sized containers.

Taking advantage of the cold in cannabis growing

As already mentioned, cold temperatures can be highly detrimental to cannabis plants, especially in their early stages of development. In this first period, the seedlings require 20-24ºC to grow properly; however, in the last weeks of flowering things are a little different.

Extra concentration of trichomes

If the plant is flowering in a well-controlled growing environment, the genetics will be able to express themselves fully, blooming without problems and forming beautiful and elegant buds with a high resin concentration. The natural function of the resin gland is to essentially protect the plant and it’s developing seed from extreme conditions like UV rays, cold weather, pests etc, and this way it works to preserve the genetic reproduction (the seeds) and ensure the continuation of the line. Taking this into consideration, it is possible to find a way of taking advantage of cold conditions and, if the timing is right, harness the low temperatures to increase resin production in the flowers.

Detail view of a leaf with a lot of resin

The cold, being a considerable stress upon the plant, triggers changes in the plant’s metabolism which, when they occur in the final stages of flowering, can lead to an increased resin production. If we gradually lower temperatures to around 16-17ºCduring the last two weeks of bloom, once the buds are fully grown and only need to mature, it’s possible to achieve a much greater and higher quality resin coverage in exchange for only a very slight sacrifice in production weight.

Pearl effect on cannabis plants

The cold and it’s effect on flavour and colour

It’s also worth mentioning that encouraging lower temperatures during the later stages of flowering will retain a higher terpene content and can lead to harvesting more aromatic and flavour-full flowers. Higher temperatures during flowering, drying and curing means that the evaporation and subsequent loss of terpenes can seriously alter and degrade the organoleptic properties of the buds produced.

Bud with a lot of resin and colored due to low temperatures

For lovers of bright colours another advantage of cold weather in relation to cannabis cultivation is the wonderful array of autumnal shades that the low temperatures provoke in certain genetics. Many plants will change the colour of their foliage to a beautiful deep purple, blue or red in cold conditions during the last weeks and when this is combined with the natural ‘fade’ colours of senescence the display can be truly spectacular and a fitting finale to a successful grow!

Variety showing deep purple leaves

Here we have a couple of examples of the color changes produced in different cannabis genetics, in particular those belonging to the Blue family of varieties. In these cases the low temperature at the end of flowering has affected the plants, provoking a very notable color change and an increased trichome concentration on the buds.

Plant with red leaves

Cannabis plant with yellow leaves

Resuming, it’s clear that if properly done, and at the adequate moment, cold temperatures can be used to a positive effect when cultivating cannabis; however, for normal cultivation, during the majority of the plant’s life cycle it is imperative to keep the temperatures within the parameters for healthy growth, between a minimum of 20ºC and a maximum of 26ºC.

Great read mate. Wonder your thoughts about watering and notes for indoor. Some say it is better to give ph balanced water two or three times then give the nutes. Others say it is better to give notes every watering but at a lower dose than what bottles say. For example bottle says 5ml per liter in weeks 1-5 but does not say how many times per week to use. I understand maybe partly must be based on observation and reactions. Also what about carbon dioxide supplementation using those pills that disolve in water. Directions say to dissolve in water and turn off extractor for a few hours but the humidity spikes well over 60% at that time. Which this and excess heat can be problematic during bloom cycle. Also bottle says can be crushed and dissolved in water and fed to roots directly (in soil) wondering your thoughts about this too. Thanks in advance!

Tim Alchimia 2021-10-05
Hi, many thanks for your comment and questions. It’s always best to adjust the pH after adding all the nutrients and supplements to the water. Whether to add nutrients in each watering or not will depend on several factors, such as brand of nutrients you’re using (most are formulated to work by adding nutrients in every watering) or the growing medium you choose (for example, hydro and coco will definitely need nutrients every time, regardless of brand). Some brands of nutrients recommend starting with 50% of the recommended dosage as it’s far easier for a plant to recover from a lack of nutrients than from a serious excess of fertiliser. As for the CO2, it’s most effective during the first 3 weeks of flowering, so high humidity pought not to be a huge issue as the flowers will only be relatively small and very unlikely to suffer from any mould problems at that stage. Even in later stages a few hours at RH 60%+ shouldn’t cause major issues as long as extraction is adequate the rest of the time. You can still leave the internal circulation fans on to move air within the grow space, in fact it’s a great idea as the CO2 is heavier than air and will sink to the bottom of the grow space if the air is not circulating. As for whether or not CO2 is absorbed by the roots, I’m unsure as plants principally absorb CO2 through the leaf stomata. Personally I’d focus on getting the most benefit from airborne CO2. I hope that helps, best wishes and happy growing!

I have some expensive seedlings that I allowed to get too cold over a couple of nights. They’re very stunted and seemed to quit growing. A couple seem to be making a slow comeback. I want to produce seeds from these seedlings. My question is, will the genetics of the seeds they produce be of lower quality because of the trauma off being stunted when they were a few weeks old ?

Tim Alchimia 2021-04-22
Hi Clay, thanks for your comment. Your seedlings should recover fully and while a cold period early in their development can definitely set them back in terms of growth and development, there’s no reason for any lasting effect on a genetic or epigenetic level as long as the plants are fully recovered by the time you make the seeds with them. Of course, if they continue to suffer one type of stress after another then it’s going to be a different story but if you give them the care they need then there’s no reason for any problems at all. I hope that helps, best wishes and happy growing!

Aye, Tim – the most durable substance in the known universe is a “cherished belief”. 🙂 FWIW, while manicuring the prematurely-harvested Thai I have discovered four (4) seeds that appear “full-term” viable (a fair number of seed pods existed but were soft/crushable and had not yet managed to become matured seeds yet). However, I don’t know if the “father” was the “hybrid” male that flowered and died and was removed about two weeks prior to the Thai males entering the flowering stage, about a month before the Thai females started to flower. Guess I’ll find out if “the early bird got the worm” next spring if those seeds actually germinate and grow. I love surprises.

Medman Mike 2019-11-25
BTW, Tim, I’m pretty sure Neem Oil isn’t responsible for Cannabis hyperemesis syndrome (CHS). The only common symptom between Neem oil / azadirachtin toxicity and CHS is the vomiting, Neem oil/azadirachtin toxicy also includes salivation, diarrhea, liver toxicity, and in extreme cases, convulsions, none of which is present in someone suffering from CHS, and is not relieved by hot showers as is the case with CHS. Plus, CHS is only observed in some people that are long term, daily, high-quantity users , and it’s unlikely that they consume nothing but Neem treated cannabis which would be necessary to get to the exposure levels needed to induce the symptoms. If they stop consuming, the symptoms go away, but for most, if they start again, even with controlled untreated cannabis, they symptoms often return, so the link to Neem oil is very tenuous. But yea.. I’m with you, I avoid putting anything at all on the plants when they gets to the flowering stage except a close eye and “digital controls” (thumb and forefinger).

Tim Alchimia 2019-11-27
Oh, absolutely. I agree with you about Neem and CHS, but some people have very fixed beliefs and it’s not easy to change them!

Medman Mike 2019-11-25
Hi Tim, Well, I was finally forced to pull the plant and put it in my curing room. Weather went from drizzle to all-day cold fog, and was forecast for hard rains followed by sub-freezing overnight temps, and botrytis was beginning to appear. The temp/humidity (80 f. and 35% rh) in the drying room stopped the botrytis dead in its tracks, only a couple small buds were lost. Even as premature as the harvest was there were some decent tricomes present, and after about 24 hours into the “cure” I sampled one of the buds – couple tokes off a bowl later turned fatal for a brand new bag of Keebler chocolate chip cookies that my gal had picked up that morning. I may take another shot at Thai next year, starting earlier and holding indoors longer before going outdoors (I started this year in late April and took the young plants – about 6″ tall – outdoors as soon as we stopped overnight frost). Maybe start in early March, and then hope fall holds off a bit longer than it did this year.. we chilled down and went rainy about 3-4 weeks earlier than normal this year which really slowed the plants down. Anyway, it looks like I’m not going to be disappointed by the crop, even though I couldn’t wait for flowering to complete and the seeds to mature. I’m growing these quite a few latitude lines north of their home turf after all, so I’m not overly surprised – either at how long it was taking, or that my initial fear of totally compromising potency with a premature harvest turned out to be unfounded. 🙂 I can only wonder how stony this one would have been “if only”. (my recollections of my days in Thailand almost half a century ago put this one about 50%, which is more than sufficient given my current “senior, frail self”. [LOL] ) Winter well, my friend.. I believe I’m going to..

Tim Alchimia 2019-11-27
Hey Mike, great to hear from you again. I’m really happy that you managed to harvest something that sounds pretty decent in the end and I’m glad the losses were bearable too! I’m really sorry to hear about the demise of those cookies though, I do hope you didn’t get into too much trouble for that! ;D As for next year, while what you’re suggesting is a great idea for huge plants, another option could be to go the opposite way and starting later on in the season, but with a greater number of plants, so that you can get the same yields as one big plant but without them ending up quite so large, which could mean that maybe you’ve got a chance of giving them some kind of cover or protection when the bad weather comes around next autumn. Just a thought. Well, you’ve got plenty of time to think about it while you’re enjoying your crop over winter. All the best and happy smoking!

Medman Mike 2019-11-15
Hi Tim, back with an update: First, I harvested the hybrid at the first sign of mold and into my “drying room” (dehumidifier in a 6 x 12 closed room, keeps the temp around 80 degrees f (26 C) and 35-40% humidity.. and stopped that mold thing in its tracks. Part of the environment here in the US Pacific Northwet. Five days of curing and I cleaned and trimmed it up, got a bunch of seeds for next year, and a nice stash of pretty stony cannabis in spite of it not being sinsemila. But that’s not what I came back to report on.. I can not believe it’s the middle of November and my Thai is still pushing on.. Had a few days here a couple weeks ago where the temps touched freezing over night – made sure they had some water before bed time, and then we went into an atypical (relatively) warm wet pattern – sporadic showers and temps between 40 and 55 f (4-12 C). The Thai female is slowly developing colas, and the Thai male is starting to die, having run its course and done its thing. I spotted developing seeds on the female yesterday, so fertilization is successful, now it’s just a race between the weather and the nature of the plant. Gray, overcast, even foggy mornings, have slowed the maturity process to a crawl, but the Thai is still working on it. We have five more days of forecast “showers with occasional sun breaks” and temps continuing in the 40-55 f range before we hit a couple-three days of clear skies and sun, and temps dropping to freezing at night (with humidity @15%, which is good for the mold issue). I suspect the weather is going to force me to harvest in another week, within two fer sure, but I’m really surprised the weather hasn’t closed us out already. If anyone had said I’d be harvesting the end of November I’d have recommended a rehab facility to check out. You suggested covering the plants, but at 12 – 13 feet (3.5 – 4m) tall that wasn’t practical, yet the Thais are pretty hearty as you noted, and I’m feeling lots more optimistic now about a successful grow than I was a month ago. I’ll do a wrap up post once it’s all “in the bag”. [ BTW, for Aaron (and others), I’ve found Neem Oil works really well keeping the bugs off.. I usually do a couple sprays a week apart a week or two after going in the ground and again later if anything reappears (particularly spray bottom up underneath the leaves).. my typical assailants are spider mites and aphids, but Neem is wide spectrum and it doesn’t take much to send the munchers away. It’s a bit pricy but a single bottle has lasted me more than two seasons now. While it’s “natural” and quite safe when used as directed, I don’t apply it (and haven’t needed to) during flowering.] // The oxen are slow, but the earth is patient. //

Hi Mike, great to hear from you again, thanks for the update! I’m very happy you got your hybrid harvested, got some smokeable herb and some seeds too, fantastic news! I feel you about the humidity, I live in the wettest part of Spain and I’m constantly facing the same problems. I’m not entirely surprised by the Thai taking so long, some can go on flowering till January outdoors! I’d recommend keeping her going as long as you can, but keep an eye on the maturing seeds, once they’re looking brown you can harvest them. I understand that the weather might make this a bit complicated, but it’d be a shame to end up with immature, green seeds that won’t germinate. If things get really bad maybe harvest everything except for a couple of well-seeded flowers to see if they’ll finish properly. As for Neem Oil, yes I’m a big fan of it, it deals with insect plants and fungal pathogens as well as feeding the plant and generally improving health. As you already know, it’s important not to use it on the flowers, and I like to stop using it well before flowering begins, just to be on the safe side. I know there has recently been some talk of Neem being unhealthy for humans, with some people even blaming it for cannabis hyperemesis syndrome. I’m not sure if there’s any truth in this, but there’s no harm in making sure there’s no neem residue on anything intended for smoking. All the best of luck for the rest of the season. Please update us when the Thai finally gets harvested, I’m really curious as to how long you can keep her alive in those conditions. Great work so far, well done! All the best and happy harvesting!

Aaron 2019-10-26
As everyone else said, awesome article! Thank you. I can’t wait to explore your site further! I currently (oh yes, on 10/26/19) have a King Tut that is almost done. There were two nights in september that the temps dropped below 29F, and so I had the plants covered for those two nights. Then I read your article. I have not actually covered them since, and the lowest it has gotten is about 30F and the KT showed no signs of ill health but it is slowing down. It was taken outside in mid July IIRC, I am going to push it about one more week before the high temps stop going above 50. They look very nice under a magnification. To stop mold issues (that other much more experienced growers local to my region have told me about) I actually have a couple small, oscillating fans around it that kick on to keep the air moving if dew is possible. Keeping my fingers crossed. looking forward to a lot more grows (this being my second, and first at all outdoors). My question: Is 16-17 weeks of flower too long? 90% of trichomes tops are still crystal clear as of two days ago. On a side note, a clone of that plant is inside and majorly infested with aphids. I have tried the soap sprays on another plant, and it mostly worked, but set the plant back like 8 weeks. I tried flower (as i read that it will kill them and it is organic, just not very fast). did not seem to lower their numbers in any appreciable way. I just ordered 300 ladybugs. I look forward to the demise of the aphids by the mercenary ladybugs. sucks that they will die once they run out of aphids.

Tim Alchimia 2019-10-28
Hi Aaron, thanks for your comment and questions. Sounds like you’re doing pretty well indeed for your first outdoor grow, nice work! Great idea to use the fans to improve air movement. How are you powering them, solar or mains electricity? I’ve looked into solar-powered fans for my off-grid outdoor plot and greenhouse, but nothing has convinced me yet. As for the flowering time of your King Tut, I’m not familiar with the genetics so it’s hard to say, but most everything but the longest-flowering Sativas ought to be ready around this time, give or take a few weeks. How is the plant looking in general? Is it showing signs of senescence such as the leaves fading from green to autumnal colours? Are the flowers still pushing out fresh white pistils or are they all brown and shrivelled now? If the plant still looks like it wants to keep going, then leave it as long as you can before cutting her down. A few days of cold temperatures before harvesting can help to increase resin production and produce some lovely purple colours in some varieties. Just as long as the plant isn’t hit by an early frost you’ll be fine. And about the aphid-infested clone, hopefully, the ladybirds will deal with the problem this time. In future, you could try a number of things. The first thing I’d do is try physically removing them, either squshing them by hand, shaking, or spraying with a water jet that’s powerful enough to dislodge the insects but not so powerful that it damages the plant. This is a great way to get rid of the majority of the infestation very quickly, before applying any kind of insecticide. Insecticidal soap usually works fairly well as part of an organic IPM program but it’s best to alternate between soaps and oils like neem or karanja, as well as pyrethrin-based insecticides in serious cases (be aware that all of these will kill ladybirds). I’m not sure why the soap treatment would have had a negative effect on the plant though, I’ve never seen that myself. Are you sure it was the correct concentration? Diatomaceous Earth is another great organic option that will work very well against aphids and other insects. Garlic products like Aliosan and nettle products such as Urtifer are also effective against aphids. I hope that’s helped, please let us know how the ladybirds get on. All the best and happy harvesting!

Medman Mike 2019-10-15
Hi Tim, Thanks for the feedback – just checked the hybrid, lots of seed pods, but not developed yet.. (dissected a pod looking for a hard seed inside but not yet, so still not time). It looks like the heartiness of the Thai is going to be tested.. what we call a “pineapple express” (stretches back to Hawaii) is arriving tonight and it’s a long train a’commin.. rain predicted to start tailing off a week from this Thursday, should get 30+ mph (50 kph) wind guests (steady 10-15 mph/20-25 kph) over the next day or two. Grow area is relatively shielded but vulnerable to the south (which is where the wind will come out of, and the Thai is in full sails-unfurled to that direction). So we’ll see. At least the wind should help keep the mold growth environment somewhat unfavorable. (Maybe I’ll get a leaf blower for the back half of the front when the winds die down ) Yea, I’m hoping to be able to do some analysis on the harvest afterwards (mathematical expression: “smoke sum”), so if given the choice between unsmokable seed bearing and somewhat smokable seedless, I’m not sure what I’ll chose at this point, Wish I had two Thai females – maybe if it gets to that (in)decision point I’ll “split the baby” and cull half the plant for curing to save what I can and let her focus energy on the remaining buds and see what happens. Hardest thing about farmin’ is always the watchin’ and waitin’ and wonderin’ part. I’ll give a “harvest report” late next month and share the cheers or tears however it works out. Looks from the Global Infared you have a “Bermuda Express” pointed at you so stoke the hearth and break out the Pais Vasco, and best of luck to you as well.. Adios por ahora..

Medman Mike 2019-10-14
Hi Tim, Just found your blog, while looking for answers to a couple questions I have.. Like a few others, this isn’t my first rodeo, but I am in a new arena, so to speak, and with an unfamiliar strain wrt growing (not consuming..). I’m up in the Puget Sound region, and I’m growing Thai (from seeds I got while in Chang Mai this past Jan.). Whole different clime and place than their genetics are conditioned for. OK, they’re huge.. 13’+, next to a couple of hybrids of unknown parentage to keep them company, two Thai plants, on male, one female. Male has flowered and is just on the cusp of dropping pollen. The female is just starting to develop colas..(and the hybrids, about 4′ tall are just on the verge of harvest). Yes, I’m going for seeds, so I’ve been pretty much hands off and letting nature do what it does). Outdoor ground grow (MG garden soil bed), and this year winter is on the fast track.. I’m getting the fall/cold rains about 3-4 weeks earlier than “normal” (assuming there’s any “normal” up here). The weather-guessers forecast a solid week and a half of rain showers and cloud cover, temps upper 50s to lower 40’s (13-4.5c). I’m not worried about post-harvest rot (my drying room is dehumidified -and can maintain 40% easily – I learned that lesson last year with my Jack Herers). My first question concerns the Thai female flowering – these plants – almost 6 mos old – are on schedule (for Thailand), but have definitely slowed with the less than normal (for them) daylight and temps, they did great with the extended sun hours up here (hence height), but now I’m in unfamiliar territory for me – extended rain during the flowering period. I note here in the Pacific ‘Northwet’ that won’t last forever (usually anyway). Since the female isn’t even close to harvest and they’re too tall to cover, what to expect going forward? The second has to do with the hybrid females..big colas, seeds prolific (hybrid males died and were pulled a week ago) but still in green sheaths. Again, sans weather, I’d let them sit at least another week or more, but since this is the first time I’ve grown cannabis for seeds, I’m not sure how to tell when those should be pulled, especially given the pending rain in the immediate future. Thoughts and advice much appreciated..

Tim Alchimia 2019-10-15
Hi Mike, thanks for your comment and questions. Wow, those Thai plants sound impressive! I’ve grown a Chiang Mai hybrid (crossed with Kali China) outdoors here in Northern Spain and it went really late but still did very well considering the humidity and low temps. I’d venture to say that the pure Thai would be even more resistant to these conditions, particularly the humidity. Low temperatures will be a little more problematic but in my experience, these plants can be very hardy indeed. The only issue might be that the maturation of the seeds could be slowed down by the cold. When I make seeds, I like to allow at least 4-5 weeks after pollination for the seeds to mature fully. If I can leave them for longer, then that’s even better. I like it when the seeds are so mature that they’re almost falling off the buds! Now, in cold and humid conditions you really do have to be careful about mould, especially botrytis, which is systemic and may well be passed on to the next generation via the seeds. If there’s any way of covering the maturing buds, particularly on the smaller hybrids where the denser buds can cause issues, then that’s going to be a big help in avoiding mould problems. Otherwise, you’ll just have to keep a really close eye on them, ready to act at the first sign of any infection. Indeed, if the plants were going to be used only for seeds, and I had no intention of smoking the flowers, I’d be using some kind of organic fungicide, possibly copper sulphate, to help ensure they stay fungi-free till harvest! Of course, if you were planning to smoke or make hash from the buds, then that’s a non-starter! I hope that’s helped a bit, best of luck for the rest of the season and happy harvest!

Terilyn L Grecu 2019-10-12
My plant is outside and in full bloom starting to get some curled brown pistols. Is 42 to cold? degrees

Tim Alchimia 2019-10-14
Hi Terilyn, if that’s the minimum temperature then it’s not too much of a problem, presuming daytime temps get up to something a bit higher. If that’s the highest temperature, then yes, it’s too cold for outdoor growing. Brown pistils can simply mean that the plant is beginning to wind down and finish flowering, it’s not necessarily a problem to worry about. Pistils will also turn brown and shrivel once pollination has taken place, so it might be worth checking around for male plants or possible hermaphrodite traits on female plants, just to be certain. All the best with the rest of the outdoor season, happy harvests!

James 2019-10-11
Hi Brian my plants are ready to be harvested and it rained for a good two days and now we’re having a cold front push in talk in a low of 35 tonight and then for the next 3 or 4 days it’s going to be sunny into the 60s should I try to harvest it tonight or just wait for the sun to come out and dry everything up

Tim Alchimia 2019-10-14
Hi James, thanks for your question, it’s always a tough call. I’d examine the plants and see if there’s any sign of mould first. If they’re looking solid then I’d leave them out for a few days to make the best of the good weather before harvesting them. If, however, you’re seeing bud rot (botrytis) then, depending on the gravity of the infection, you can either remove any affected areas and leave the plants for a few days, or simply cut your losses and harvest the plants before the mould spreads and spoils the rest of the plant. I’ve had the same dilemma myself this year, some plants have withstood serious rains with no problem, while others have very quickly gone from kush to mush in the few days after the rain. All the best for the rest of the season, happy harvesting!

Brian 2019-10-04
Hi i have a question,i have a plant that has already been flowering and does have a little of orange hairs going but its supposed to be only a high of 59,low 60’s.should i have them outside?i dont have a indoor or anything.and it gets to 46 at night

Tim Alchimia 2019-10-07
Hi Brian, those kind of nighttime temperatures aren’t low enough to cause any damage, and as long as it’s warm during the day you should be fine. You could try covering plants with horticultural fleece overnight to protect them a little, or move them indoors at night (as long as they stay in the dark, of course), but really I’d only be concerned about frosts, which could kill the plant. All the best and happy harvesting!

Aj 2019-09-19
The part about the cold saying that if it gets below 65f 18c degrees most plants will struggle. I have to highly and I mean highly disagree with this statement. It really all depends on strain while northern lights likes cool climates African landrace seeds tend to like warm dry weather it doesn’t mean they won’t flower or won’t produce. maybe your thinking about if plants are in pre flower and these temps happen but again I’m not so sure. I have done pheno tests for strains that I like due to my cold climate I have done some crazy things to plants and only seen a select few clam up and become unresponsive almost like a nutrient lock but that was when plants experienced hard cold while just starting to flower or in pre flower. I have plants going and I haven’t seen a day above 65f in about of week my plants are outdoors nights have been as low as 38 f and they are loving it getting fatter and sticker daily. Strains are legend of Nigeria, purple dream Hindu Kush and granddaddy purple crossed with nyc sour desiel. I would recommend all of these strains for cold late flowering conditions.

Tim Alchimia 2019-09-23
Hi Aj, thanks very much for your input. I think it depends greatly on genetics, some varieties will deal with cold weather very well, like Hindu Kush and other genetics originating from high altitude mountain areas, where temperatures can get very low. Other varieties such as tropical Sativa genetics will definitely struggle with low temperatures. All the best and happy growing!

Mark Barrett 2019-09-11
Hi Tim Alchimia, This is a great website. I was looking for information on cool temperature effects on my maturing plants. I have one AC/DC clone that has grown about 6-7 feet with many branches covered with thin, whispy buds, several hybrid clones (Sativa dominant), and some Thai indicas, that are about 7 feet tall without any sign of sex. Aside from the Thais, all are well into flowering, with mostly clear trichomes, and we have just hit a cold snap with temperatures down around 44 degrees at night and into the 70s in the day time. Should I be worried, or just stay the course for a normal crop? I did allow male plants to pollinate the females in order to get seeds. Does seeding cause the plant to mature more quickly? Thanks for your much appreciated advice!

Tim Alchimia 2019-09-17
Hi Mark, big thanks for the comment and your kind words. At this stage in the season, with the trichomes still clear, there’s not much you can do apart from wait and see. It’s too soon to pull the plants early if all the trichs are clear, it would be a total waste of all your hard work. That kind of temperature isn’t ridiculously low, plants will carry on growing right down to nearly freezing, and the daytime temps are good for flowering, as long as there’s no frost, I think you’ll be fine. If things get really bad, you could try covering your plants overnight with horticultural fleece, it should protect a little, and breathe enough to avoid condensation building up, although your 7ft-tall plants may well look like giant ghosts! In my experience, pollinated plants generally don’t mature any faster or slower than non-seeded plants, but if you want to get large, healthy and vigorous seeds then you’ll need to harvest at the optimal time for the seeds, rather than for the flowers or trichomes. I often let seeded plants go for a week or two longer than non-seeded plants, just to ensure the seeds are fully mature. At this point, all the trichomes are amber and the buds are slightly past their peak, although this also depends on personal tastes. I hope that helped. All the best and happy harvests!

Cindy 2019-09-08
Thank you for all the great information! I have 6 Painkiller, not autoflower, (Farmers Lab) plants in 10 gallon fabric pots that have been outside all summer. (Southeast Michigan) The seed supplier has pics of mature colas that have purple sugar leaves and mine do not have them. I have looked at the Trichomes and most of them are cloudy, so I’m ready to harvest. Our temps have been 70-80 daytime, 50-65 at night for the last 2 weeks. What triggers the color of the leaves and buds? Night temps., genetics, fertilizer, stress?

Tim Alchimia 2019-09-16
Hi Cindy, thanks for your question. Apologies for the delay in replying, I had some time off work. The purple colours shown by cannabis plants are dependant on a range of factors, but principally it’s down to genetics. Some plants (like ACE Seeds Violeta) will develop purple flowers in almost all plants from the very beginning, regardless of conditions, whereas some plants will start flowering as a green colour, developing purple tinges as flowering goes on, particularly when temperatures are relatively low at the end of the blooming period. However, these characteristics can only be displayed in plants genetically disposed to colour. Some varieties will remain green, no matter how cold they get. I hope that’s helped, all the best and happy harvests!

Austin 2019-05-18
Hi I recently played my green house and now we are looking at a 3 week cold front will my plants go into shock what can I do to keep them happy ??

Tim Alchimia 2019-05-27
Hi Austin, thanks for your question, sorry for the delay in responding. If your greenhouse doesn’t have mains connection for an electric heater, you could use a paraffin heater to keep the temperatures. If buying a heater isn’t practical, you could try covering the plants with horticultural fleece overnight to insulate them from the worst of the cold. Other more or less practical approaches could include, for example, a large black barrel filled with water to accumulate heat from sunshine during the day and slowly release it at night, or a big pile of fresh manure that would generate heat as it decomposed, although both of these would occupy space within the greenhouse. I hope that’s given you some ideas, and I hope your plants make it through the cold spell unscathed. All the best and happy growing!

jill coburn Is an Alchimia client 2019-04-10
Howdy , growing pineapple chunk in southern Australia, outdoors , plants are into 2-3 weeks of flowering , but the nights are now becoming quite cold, is it possible to move indoors where there are plants at 18-6 hour light ratio , would this be too confusing for plants , which outdoors probably are getting 12-14 hours of light per day. The weather will continue to decrease in temp as the days go by, love to here what your view is ?

Tim Alchimia 2019-04-11
Hi Jill, thanks for your question. I definitely wouldn’t advise moving the plants indoors if the lights are on 18/6 as this will halt the flowering process and provoke re-vegetation which will really stress them (and you!) out, and they’ll take a long time to readjust when you put them back outside again. At this point, the best you can do is to give them some kind of shelter on cold nights, even if it’s as simple as moving them next to a building for extra warmth and draping a horticultural fleece or a sheet of plastic over them (although fleece would be better as it won’t cause condensation). But more than anything it’s vital to keep them away from light sources that could interrupt the natural flowering cycle, so street lamps, exterior lights on houses, billboards etc are all things that must be considered. I hope that helps, all the best for the rest of the season and happy growing!

Tim 2019-01-29
What temp does the water I am giving my plants need to be? I had been giving them room temp and everything is good but I’ve read that watering them with cold water, not freezing just like out of the fridge, will increase trichome production. Is any of that true or would I be hurting my plants? I did water one with cold water that has been in flowering stage for 9 weeks. It’s a sativa and the trichomes are still clear. And the colas the next few days did seem to have ALOT more trichomes.

Tim Alchimia 2019-01-30
Hi Tim, thanks for the question. I’ve definitely heard of people doing a cold water flush for the last week or so of flowering to increase trichome production. Putting cold water onto the roots is always going to cause some mild shock, and it won’t do the microbial life of the soil many favours either, but during the last few weeks as the plant s winding down to harvest that is of lesser importance, so I don’t see any reason not to try it. Whether it works or not is a different issue. To find out if it’s just another stoner myth (as I suspect it might be) you’d have to run the same clone in the same grow space in the same conditions, but flush one with cold water while you treat the other normally. Then you’d be able to see if there’s any notable difference between the two. If you do try this, please let us know how you get on. All the best and happy growing!

Brad 2018-10-24
I have a plant in my green house its oct 24th and at night it gets down to -2 right now but the plant seems to be doing good still how long can I keep it in there the hairs are all still white for the most part

Tim Alchimia 2018-10-25
Hi Brad, I’m happy to hear your plant is doing so well in the cold weather, some cannabis genetics are much more able to deal with these types of temperatures than others, and yours seems nice and hardy. In your position I’d simply keep a close eye on it, and as soon as you see any signs of it suffering from the cold, then I’d start thinking about harvesting. It’s a balance between cutting too early and losing some flowers to possible mould issues. All the best and happy harvesting!

Josh 2018-10-22
Heres a question for you. If you harvest freah flowers with seeds in them and freeze before drying would it sterilize the seeds? What about at -30f ?

Tim Alchimia 2018-10-23
Hi Josh, I’m not sure about sterilising them as such, but I think it would mess them up pretty badly. If they’re still fresh then I wouldn’t expect them to be still viable, I think that freezing them with moisture still present would result in a massive degradation of the cells inside. That said, seeds that have been properly dried will be able to be kept in the freezer for long term storage. I hope that answers your question, all the best!

Patsy 2018-10-13
Hi, I am waiting to harvest my first grow in western Colorado at 7000 ft. We are in a canyon so a little less sun. I have Northern Lights Indica and Blue Dream Sativa. My trichromes are mostly white on both varieties but waiting for amber. The temps have been getting down to 30 deg F at night and the Indicas are turning purple but none of the plants look stressed. I have a heater that keeps it at 30 deg. I am wondering if I can leave them in the ground to dry, they are in a makeshift hot house with plastic to keep them protected from frost and wind. I read its good to cure them slow so wouldnt it be better to allow them to cure in the ground as long as they dont reach the point of being overly “ripe” where the thc will start dropping? I also thought it would allow the branches I pollinated to devevelop more mature seeds. Your thoughts would be appreciated.

Tim Alchimia 2018-10-17
Hi Patsy, thanks for your comment. I wouldn’t recommend doing what you’re suggesting. The plants will continue to ripen far beyond the point of optimum maturity, so you’ll end up with mostly amber trichs and a really heavy, stoney effect, although that may be exactly what you’re looking for! Also, drying cannabis in a light and warm environment such as a greenhouse will degrade the THC and the terpene content, there’s a reason we always recommend drying in total darkness in a cool, but not too dry room. Personally I’d cut the plants at your desired point of ripeness (Personally I prefer it with very few amber trichomes) and if possible leaving the pollinated branches to mature further (always a good idea for seed production, as immature seeds are useless). Then move the harvested plants to a dark room for drying. Slow drying involves hanging plants in rom with a RH of 55-65% and temperatures of 15-20ºC for 2-3 weeks. I hope that’s helped, good luck and happy harvesting!

Dan K. 2018-10-13
I live in East central mn and I’m wondering what I can do to keep my plants going till end of October to get the most out of them. Strains are unknown and I’ve only been giving them fox farm big bloom nutrients from the start of flowering once every week. Started by giving 3 cap fulls per 3 gallons of water for 4 plants. Plants are from 3 ft being the shortest one up to 6’6″ being the tallest. The two shorter two have become very dark purple bur still some green inside by stem and centers of inner buds. Tallest two are still green no color change at all it seems. But after the other night all the fan leaves look dried out and wilted upward and goimg towards the plant. The puprle two are the worst and all i have for a greenhouse is 4 mil thick plastic sheeting. It came as its about 2.5′-3′ wide and about 6′-7′ long. The plastic was only 3′ wide so its in two sections to make high enough to cover all but 6″ of tallest plant. Than a 3′ section over the top. I tide the sheets together at all the seems but left vents open all around the sides for some air flow. I dont have a micronscope to check trichomes and its been very cold and rainy the past 1-2 weeks. If I’m gunna end up harvesting early is there anything I can do right now to make the plants produce more trichomes and highten the terpene content? And is there anything I could do to make my slapped together makeshift greenhouse better at protecting the plants and the root systems which is in the ground not pots. Is it possible to dig them all up? And if I’m right around the corner of harvest cause of the climate can I take the tops and the other buds that are closer to maturity and leave the smaller ones to mature more and faster? Sorry for all the questions but its my first grow on my own and trying to get the most possible out of them in quality since I dont think they were able to fill out 100%. I’m guessing they should be as big as pop cans or end of baseball bats but they are more like a glass coke bottle or the bottom of a baseball bat that keeps your hands from sliding off. Not as frosty as I wouldve thought so anything that 100% works to increase terpenes and trichome content is much appreciated.

Tim Alchimia 2018-10-17
Hi Dan, thanks for your comment and question. I’m glad your garden is doing well this year. At this late stage there’s not much you can do to improve the THC or terpene content, apart from letting plants flower for as long as is possible in the bad weather, flowers that are harvested before they’re mature won’t have the same fully developed terpene profile or the same effect as properly finished buds. At this stage I’d personally just give them water only until they finish, that way you’ll at least have good tasting and clean burning weed that won’t be full of excess nutrients at harvest time. Adding more nutrients or bloom boosters isn’t a good idea at this stage, early in flower is the best time to be thinking about these things, not just before harvest! So, if you’re expecting frosts then you’re doing the right thing by covering your plants. It’s hard for me to visualise the setup you’ve got going on with the plastic to advise you but if I’m honest, anything other than a proper framed greenhouse/poly tunnel is going to be a bit of a botch job and probably won’t stand up to wind and rain very well. The best thing is to secure it as well as you possibly can, and if there’s an issue with the height of the tallest plants then maybe try gently training the top of the plant and tying it down a bit to lower it, if it’s the difference between being protected or not. As for protecting the roots, well they’re definitely better off in the ground than in plant pots at the stage, they won’t be as affected by the frost but you could also add a heavy mulch layer of straw or hay which could help to buffer the cold temps. Also piling some hay baes around the base of the planted area would help to keep temperatures higher in the root zone, and prevent the frosty air from reaching the plants. Digging up the plants will shock and stress them to much and they’ll most likely stop growing and maturing altogether, so definitely not recommended! You can definitely harvest the top buds first and then let the lowers fatten up a bit before chopping them, that’s always a great idea if time allows for a two-stage harvest. The size of the buds will depend on many factors, primarily the genetics (so it’s vital to invest in good seeds or clones rather than planting any old thing and hoping for the best), but also nutrients, solar exposure and irrigation can all have a huge effect on bud size. In short, the better you grow, and the better the genetics you grow, the more you’ll harvest. I hope that’s some help to you, all the best for the rest of the season, happy harvesting!

If the temperature drops below freezing while the hemp is still in the ground is it still viable? I’m in Colorado and growing cherry and super cbd strains. We got caught by early cold snap.

Hi and thanks for the question. Hemp ought to be more hardy than regular drug cannabis, but it still won’t tolerate extended periods of extreme cold. If it’s just a short cold snap then you’ll probably be fine but if it’s cold for a few days to a week then it’ll start to have an effect on the plants, slowing them down and stopping growth, and you may see the appearance of some mold or other deterioration in the flowers where frost has damaged cells. That said, a lot depends on the position and topography of the site, some places will suffer worse than others, if for example you’re growing in a low dip or a bowl, frost will be more severe, but on a south facing hillside with good solar exposure and air movement you may see no effect at all from the cold. My advice is to keep a close eye on the weather forecast and carefully check the plants for damage and be ready to harvest at the first sign. If there are local farmers you can ask they’ll probably be able to offer better advice than we can. All the best and happy harvesting!

I live in Colorado bad weather has hit 30 at night 40 during the day in week 8 still to early to pull according to the weather man we will have these temps for the next 6 days with rain . covered the plants with easy ups .that’s all I could think of .do you think they will make it? Would appreciate some advice.

Tim Alchimia 2018-10-09
Hi Steve, thanks for your question, I’m sorry to hear about the bad weather. You’ve definitely done the right thing by covering the plants and protecting them from the rain. By keeping the majority of the water off them you’ll do a great deal to help prevent bud rot. It’s also a goos idea to try and increase air movement, either by using some fans if possible, or by removing some of the lower leaves that aren’t getting much sunlight. Apart from keeping a close eye on the buds for any sign of botrytis, and removing any you find, I don’t think there’s a great deal more you can do at this point. Of course if you start to see a great deal of bud rot then you’ll have to make the decision whether to pull the plans slightly early or run the risk of losing the whole crop. It’s at this time of year that our choice of genetics can make or break the whole season. All the best for the next couple of weeks, I hope the weather improves and you get a great harvest!

My first time growing a plant si I just have ine..think I did ok my question is I was told it have about 2 more weeks before it’s ready but it’s getting a little cold and hardly any su, should I just pull it now are will it be ok..not sure when its completed ready

Thomas 2018-09-29
Hello, I live in Southern Ontario and yesterday I found one of my bud rotting under yellow leaves. Outdoor grow. Cut out the bud and branch it was on. Overnight I covered the plant (Indica) with poly and this morning no additional rot. Weather forecast next week is cool and wet. Average 20c high 14c low. Also expected to rain every day but one. Should I harvest plant now. It seems to me would be a struggle to avoid more rot . May thanks for your advice

Tim Alchimia 2018-10-01
Hi Thomas, thanks for your question. If the weather’s looking bad for the next week, it’s probably best to harvest as long as you’re happy with the maturity of the flowers. Have a look with a microscope and check the trichomes. If they’re mostly transparent then it’s not ready, but if they’re mostly milky coloured than you should be ok, some people like to wait to see 20-30% amber trichomes, but I don’t think you’ll have the luxury of time to wait that long. I think you’re right though, it’ll e a battle to keep the mould at bay, especially if it’s covered with plastic at night, which will create condensation and high humidity, the perfect conditions for more mould. If you wait much longer you may well lose the whole plant. Without being able to see the plant, I’d say harvest asap to salvage it. I hope that’s some help. All the best, good luck and happy harvest!

Jay 2018-09-23
Hello. Well I live in north west Ontario Canada. Not the best cannabis growing climate. I did have early finishing photogenic phenotypes this year. But my main strain being fire og X Cinderella 99, now this being late September we usually can grow till mid oct in my greenhouse before snow starts to fly. Not this year, woke up to a light dusting of snow this morning. I put a new sheet of poly over top of my greenhouse to close it all up, my plants have beautiful stacked colas but are still at least two – three weeks from being at optimal harvest. I read in your article that resin and terpenes (which are off the hook now) get more and more prevalent. My ? Is will the only effect of these low temps I’m experiencing be with the final weight and not resin and terpenes? It’s my medicine and would hate too see my winters stash all go down the botritis hole. Will these low temps -4 at night +18 during daytime, cloudy, wet northern autumn weather. Hope the new plastic sheets will help retain heat and keep moisture off my flowers. Thanks for any helpful tips.

Tim Alchimia 2018-09-24
Hi Jay, thanks for your comment. Well at least the plants are in a greenhouse and protected from the worst of the weather, but my main concern now would be adequate ventilation and air movement, especially if you’ve completely closed the greenhouse up with this new layer of plastic. If there’s any possibility of doing it, I’d put a fan or two in there to keep the air moving and avoid condensation on the inside of the plastic, which will definitely not help your fight against botrytis. Even better would be to add a dehumidifier too. Apart from that, yes the cold temperatures will restrict growth a little, but they shouldn’t affect the terpene or resin content, in fact the low temps will mean that the terpenes will be better retained, not evaporating off in the heat of the day. I hope that helps a bit, all the best for the next few weeks, good luck and fingers crossed for a happy harvest!

Carolyn 2018-09-16
This is sorta for Dan Carte. Hello! I’m not a first time grower so I have a few years under my belt . I’m not an indoor grower I prefer outdoors. Elevation here is about 2900ft daytime temperatures are usually between 90 to 110* F. Nighttime temps range between 75 to 87* F. Until around late August then in September daytime is between 90 and 102* F nighttime down to 60* F. In my opinion the cooler temp at night is one of the best things that can happen to the plants. At this time of year all your growing is done they are just maturing. Since the plant starts feeling like it’s going to die because of the cooler temps it’s possible to achieve much greater and higher quality resin coverage. You don’t really want amber trichomes at that stage they start to deteriorate. Also what I do one week before harvesting is I split the stock and wedge a rock in it, then stop all watering and cover the plant with blackout material. I then wait 3 days take the cover off and wait about 4 to 5 days and harvest. The stem is empty and hollow and the resin is unbelievable. In my opinion our altitude is almost perfect for plants. I’ve never seen better grows anywhere. And I have tried the molasses thing and for all its worth, I didn’t really see a difference. Splitting the stock is amazing though. Happy growing.

Dan Carte 2018-08-28
Hi Tim great article! Very informative. I am growing for the first time in the Rockies of western Montana at an elevation of 3200 feet. Several questions. I planted three seeds of unknown strain in a large container good organic soil and natural fertilizer. Have had incredible results with one plant in particular. I am guessing given my growing zone is a sativa. I am looking for medicinal benefits to help ease my son’s seizures as well as recreational benefits out of this same plant. I have huge tight buds loaded with trichromes that I photograph each morning as soon as the bud is in full sunlight. The trichromes are mostly milky with maybe 5% still clear and none have yet turned amber. My plant is healthy and is turning a beautiful purple color with recent cool temperatures at night. Dipped to 2 degrees Celsius last night but still reaching 26 degrees during the day. I have several theories about my success I hope you can confirm or deny. There is less atmosphere at my elevation than at sea level to protect from the sun’s uv rays, does this increase trichrome production? Given the temperature range from a seasonal norm of 6c at night to 26c by midday for possibly another month what impact on yield and maturation will this temperature range have? I have read that cbd’s are most potent at a trichromes stage where they are 60% amber, is this true? Have heard adding molasses to water at this stage of bloom will increase trichrome production, is this true? Drone comparing daily photos I see what appears to be continued trichrome production or at least a thickening of them. I am hoping to harvest in two stages part when trichromes are at best for a recreational use and later for maximum cubs medicinal use, is this possible? Is this wise?

Tim Alchimia 2018-08-30
Hi Dan, thanks for your comment, I’m so happy you’ve enjoyed the article! Yes, I think your theory is correct, trichomes are thought to be the plant’s protection from UV radiation, so it makes complete sense that they should be producing large amounts at your elevation, in the thinner atmosphere. Just think about traditional hash-producing countries like Afghanistan and Pakistan, where the best plants are grown high up in the mountains. Those place also experience a drastic difference between daytime and nighttime temperatures, just like your spot. As for any influence this may have on maturity, well I personally think that it will probably accelerate maturity, with this temperature difference being a natural process experienced by the plant over millennia. As for your question regarding CBD, that’s another matter. You say the genetics are unknown, so unfortunately there’s no way of knowing if the plants are genetically capable of producing CBD. Aside from CBD-specific strains, most of the genetics on the market will only have trace amounts of CBD, because for years cannabis breeding has focused on increasing the high, for recreational purposes. If you really need to be growing for CBD, then I’d highly recommend getting some high-CBD varieties, they are increasingly easy to find as awareness grows about medicinal cannabis. As for the two-part harvest, that’s a good plan, even without any CBD. The tops will mature first, you can cut them and then wait a week or two for the smaller, lower buds to mature and fatten a bit before cutting the rest of the plant. Hope that’s been some help to you, best wishes and good luck for the rest of the season, happy harvests!

Anthony Reynolds Is an Alchimia client 2018-07-07
Bit of a weird question, due to a heatwave here temps are difficult to control in the day time, so I changed the cycle of the lights so they come on in the evening when the air temp is a lot cooler and switch off just before midday, I have fans and temp controllers, so I assumed everything would work ok. But that isn’t happening and I havn’t a clue why, this isn’t my first ‘Rodeo’ BTW, but there is a problem with the plants, they are very sluggish and some are stressed, causing what looks like an over fertilized condition, puzzled by this as they havn’t actually had any Nutes yet, I decided to investigate. It transpires the daytime temps i.e. without lights are almost 28 to 30 degrees centigrade! This brings me to ask the question, do plants need a drop in temperature to thrive, I’m not talking a radical drop but a temperature variation, like would occur naturally at night?

Tim Alchimia 2018-07-10
Hi Anthony, thanks for your question, sorry to hear your plants aren’t happy. Those night time temperatures are a definitely on the high side, and that kind of heat will definitely reduce the quality of the end product, which will have a lower terpene content. We’d recommend trying to lower them to 23/24 if you can. It’s unclear whether plants really need lower temperatures at night, usually growers face the problem of temps being too low, rather than too high. However, in the wild, the plants metabolism has evolved over millennia to deal with lower temperatures during the night, so it’s logical that plants will grow better and be happier with less stress in more natural conditions. I hope that helps, all the best and happy growing!

Den Is an Alchimia client 2018-01-27
Hi, question for you. I have a DWC grow that was going lovely, started flowering – got to day 15 (lots of great explosive sites formed to grow flowers) then had a cold snap where temps dropped to 18 high /10 low and all growth stopped (plants stayed healthy green but no more floral growth developed) this continued for 3 weeks. Then managed to increase temps to 26/20 and growth started again – my question is this: will the plants finish as per seed catalogue guidelines with a much reduced yield or will they continue to full maturity albeit taking an additional 3 weeks of time (given the low temps induced dormant spell)?

Dean boutilier 2017-12-29
My grow room dropped below freezing for a few hours some but not all plants are dropping will they recover

Tim Alchimia 2018-01-02
Hi Dean, a plant’s resistance to cold really depends on the variety you’re growing. Some can deal with freezing temperatures without any problem (not for long periods of time though) while others will start to show problems way before getting that cold. In your case you’ll have to wait and see, but it’s certain to have caused some kind of stress to the plants, you could try using an enzyme product of some kind, which can help the plants recover quicker and mitigate the effects of the stress. Investing in a small tube heater can really help these problems in the future. All the best, stay warm!!

Evelyn 2017-12-28
What temperature is ok for the dark room after blooming

Tim Alchimia 2018-01-02
Hi Evelyn, thanks for asking your question. I’m not 100% sure what you’re asking, but if you mean the nighttime temperature during flowering, it should be around 20-22ºC to keep plants as happy as possible. I hope that helps!

Are cannabis seeds legal in new zealand

New Zealand

While New Zealand still looks forward to a 2020 General Election Referendum on cannabis decriminalization (the actual ballot text is not yet available), medicinal use is legal in very limited circumstances. The decriminalization referendum came about from a petition in the legislature, and the referendum before voters will be binding, meaning it will be required to be implemented if it wins a majority of votes. Interested parties should refer to the Electoral Commission site for updates on the text and voter information.

Medical use was legalized under limited circumstances via the Misuse of Drugs (Medicinal Cannabis) Amendment Act Bill 12-2 in December 2018. Exemption from prosecution is secure for qualified patients prior to the implementation of a national cultivation supply, which must occur by December 2019.

Cannabidiol (CBD) and Sativex are possible to prescribe without ministerial approval. Industrial hemp must contain less than 0.35% THC and must be made by a licensed producer. Advertising hemp with intoxicating properties is illegal and is governed by the Misuse of Drugs (Industrial Hemp) Regulations 2006 .

All other cannabis products are Class B1 controlled substances, and can be prescribed only to those with a terminal illness requiring palliative care. Palliation is certified by a medicinal practitioner or nurse practitioner who attests that the individual has an advanced, progressive, life-limiting condition and is nearing the end of life. Previously, the only use permitted was for those in the last 12 months of life, as determined by a physician. Cannabis use is also permitted for multiple sclerosis spasticity, but both conditions require a medicinal practitioner to submit an application.

Regulatory authority

The Ministry of Health is responsible for developing and enforcing rules around medicinal cannabis as well as cultivation licensing, guidance for growers, and formulation of a domestic cultivation and taxation framework. They also govern industrial hemp and CBD regulations.

Prescribing medical cannabis

The Ministry of Health developed a flowchart to help clinicians navigate the process of prescribing and the numerous approvals that are required. The options for prescription are extremely limited and generally approved via a case-by-case application submitted by a medical or nurse practitioner. Complete guidelines are available here .

  1. Sativex is a nasal spray which must be prescribed per Medsafe guidelines . There is a long titration period of gradual dosage increase which must be adhered to. A prescription for Sativex to treat multiple sclerosis does not require an application.
  2. Applications for other new pharmaceutical-grade and nonpharmaceutical-grade products must meet a list of requirements and be sent to [email protected] .
  3. CBD products that contain enough THC to be intoxicating are available only through a prescription.

Consuming medicinal cannabis

All plant and plant derivatives are allowable under strict medicinal conditions.

Travel

New Zealand offers guidance for importing medicines and the national laws and regulations are universally applied within its borders. No U.S. products are permitted, as the U.S. still federally prohibits cannabis. Otherwise, import is permitted if a patient declares the following to N.Z. Customs, certifying that the drug:

  • is required for treating a medicinal condition for you or for someone under your care who is traveling with you;
  • has been lawfully supplied to you in the country of origin
  • is no more than one month’s supply.

Cultivation licensing

Personal cultivation is not legal and medicinal cannabis is tightly controlled. A license for growing cannabis can be only applied for a medicinal prescription application.

Per the Ministry of Health : “Applications will be considered on a case-by-case basis. If you do not have details of who your product will be supplied to or that person does not yet have the appropriate licenses, you may have a condition on the license that product cannot be supplied. This can be updated as more information becomes available.”

Formal licensure can be pursued only for medicinal use or scientific research in clinical trials. Commercial cultivation is prohibited. There is a fee schedule available:

Currently, there is no cultivation licensure fee for:

  • growing cannabis
  • harvesting cannabis
  • drying cannabis
  • storing cannabis
  • possessing cannabis and its seed.

Currently, a NZ$966 fee applies for dealing licensure:

  • possessing cannabis, seeds or cannabis products
  • storing cannabis, seeds or cannabis products
  • extracting, processing or hulling cannabis and its seed
  • manufacturing products from cannabis, cannabis extracts, or cannabis seed for scientific research only
  • selling or distributing cannabis, seeds, or cannabis products.

Currently, a NZ$13,750 fee applies for manufacturing medicinal cannabis products or active pharmaceutical ingredients (API) for therapeutic use, currently allowed to be manufactured for clinical trials only.

A separate import or export application fee of NZ$194.22 is added to a dealing license, requiring separate applications for each activity.

Industrial Hemp licensure is NZ$511 and can be obtained by emailing [email protected]

CBD and hemp

The Misuse of Drugs (Medicinal Cannabis) Act Amendment Bill 12-2 permits up to 2% trace THC in a product before requiring it to be prescribed as a THC product. The Misuse of Drugs (Industrial Hemp) Regulations 2006 define industrial hemp by its THC content, which must be below 0.35%.

Are cannabis seeds legal in new zealand

Marijuana legalization is a hot topic throughout the world right now, and it’s no different in New Zealand. While many places have legalized medical or recreational use for residents, New Zealand still has strict laws regarding possession and cultivation. However, a new referendum is in place that could change these laws and allow residents to enjoy medical or recreational marijuana throughout the country. As of right now, since the laws have not passed or been enacted, it is still illegal to possess or cultivate marijuana. Still, residents in New Zealand do have the option of purchasing cannabis seeds for their personal collection. If you’re in New Zealand and looking for marijuana seeds, check out our large selection now to find the best ones to add to your collection.

Marijuana Laws and Legislation in New Zealand

Right now, it is not legal to possess or consume marijuana for recreational or medical purposes in New Zealand. However, there is a referendum that is up to vote on regarding the legalization of marijuana. This is still in the very early stages, but it does provide hope that legalization is just a short while away. This referendum would set a minimum age for the possession of marijuana as well as restrict where it can be consumed and create a license for businesses. It would also limit advertisements and promote public health education in all of the states of New Zealand.

New Zealand states, including Auckland, Waikato, Northland, and Taranaki, do not have individual laws right now allowing for the possession of marijuana. Bay of Plenty, Gisborne, Hawke’s Bay, and residents of Manawatu-Wanganui, as well as Wellington and the remaining states, do, however, have the option of voting on the referendum and have a say in what could happen in the future.

One state, Northland, has been pushing for legalization for some time now. Known unofficially as the “marijuana capital of New Zealand,” Northland has made headlines in the past with major grow operations being busted. The area is known for its weather and would be a perfect environment to grow marijuana if it were legal to do so. Northland has been trying to trial marijuana legalization as far back as 2012. As of the time writing this article it is still illegal to cultivate marijuana in Northland and other states, though changes may be coming to New Zealand as a whole.

Right now, the referendum in New Zealand does not quite have the support needed to pass. As of December 2019, there were around 45% of voters who were for passing the referendum. If it does pass, it will take some time for everything to get sorted out and for laws to change before marijuana will become legal.

Can You Still Buy Marijuana Seeds?

Those in New Zealand may not be able to purchase marijuana seeds locally because of little availability, but that doesn’t mean they cannot start a collection of marijuana seeds. Instead, they’ll want to purchase souvenir cannabis seeds. These are the same as those intended for germination, but they’re bought with the idea of starting a collection instead of germination. They are still viable seeds and can be germinated in the future. The idea behind this is mainly to start collecting seeds now, so when the laws do change, the buyer will already have a number of strains to pick from and can start growing their own plants right away.

A seed collection can be as small or as large as the collector would like. It’s just important to ensure the seeds are high-quality seeds and to make sure they are the strains the collector finds interesting or that they might like to grow if the laws change. Cannabis seeds can be collected and saved for the future, though seeds that are known as being more difficult to germinate may not be as good as an option for souvenir marijuana seeds compared to ones that are easier to germinate.

Buying Seeds to Use as Souvenir Seeds

Any marijuana seeds can count as souvenir cannabis seeds, as long as they’re not germinated. The intention is what matters here as seeds can be collected but cultivation is still illegal. Buyers can pick out the strains they prefer and order the seeds online through a reputable seed bank like i49. This gives them the opportunity to purchase different strains as well as different types so they can have a large collection ready once laws do change.

It is not yet known if the new laws that could come into play are going to allow for cultivation. However, if marijuana is legalized, cultivation could be allowed from the beginning or may be legalized later on. Those who collect seeds will be able to use their seeds as soon as cultivation is legal, especially if they have stored them properly. Those who are starting a collection with the intention of cultivating marijuana once it becomes legal can buy as many seeds as they would like, pre-legalization.

Marijuana seeds need to be stored in air-tight jars to prevent moisture from getting to them. They also need to be stored somewhere that is cool, and that is dark all of the time. This helps prevent light and warmth from reaching the seeds. As long as the seeds are stored properly, they will continue to be viable for at least three years. This way, if the laws do take some time to change, the collectors won’t have to worry about whether they will be able to germinate the seeds once cultivation becomes legal.

After cultivation becomes legal, some collectors may have older seeds that they will want to try to germinate. As long as they’ve purchased high-quality cannabis seeds from the beginning and made sure they stored them properly, this shouldn’t be an issue. Seeds can be tested to see if they are still viable, a process that can happen just before planting. Once the collector is ready to grow a plant, they can germinate the seed to produce a taproot that will be planted into soil.

What Type of Marijuana Seeds to Buy?

Marijuana seeds come with different labels, depending on the type of seed they are and what is needed to grow them. This includes regular seeds, feminized seeds, and auto-flowering seeds, all of which will be a great option depending on what the person wants when they grow the plants.

  • Regular Marijuana Seeds – Regular marijuana seeds produce both male and female plants. This is great for the grower who wants to breed new strains, as the male plants will pollinate the female ones. This is not so good for those who are just looking to harvest marijuana for personal consumption. This means growers will need to watch the plants carefully during the vegetative phase so male plants can be removed and used for something else before pollination can occur.
  • Feminized Marijuana Seeds – Feminized marijuana seeds remove the worry about male plants growing for those who just want to grow marijuana and not worry about saving seeds or breeding new strains. Those growing feminized seeds, especially indoors, will need to pay attention to the lighting schedule for the plants as they near the end of the vegetative stage. Marijuana plants are photo-dependent, so the number of daylight hours will need to be adjusted to enable them to begin flowering.
  • Auto-Flowering Marijuana Seeds – The last type of cannabis seeds is auto-flowering. These produce plants that are not photo-dependent, which means they will start to flower at the right point in their growth cycle, even if the lighting schedule isn’t changed. Often, auto-flowering seeds are also feminized, so they only produce female plants. This makes them an excellent option for beginners, as they are relatively easy to grow and don’t require as much care compared to photoperiod plants.

Try Out These Cannabis Seeds

When you want to purchase cannabis seeds, whether they’re for a collection or for growing, it’s important to choose the right ones to buy. There are a number of different ways to sort through the hundreds of seeds available on our website to make sure you find the perfect one. We offer a number of different categories, so you can find what you’re looking for and browse through everything that might be available to find new strains you might not have tried before.

For beginners, it’s helpful to look for seeds that are easier to grow. This enables them to get started with a smaller time commitment and have a much higher chance of getting a good harvest out of the plants they grow. Auto-flowering seeds like our Auto Moby Dick feminized seeds, as well as our Auto Gorilla Glue #4 feminized seeds, are some of the easiest to grow. Feminized seeds like our LA Confidential feminized seeds and Trainwreck feminized seeds are very easy to grow as well.

New collectors may want to go with what’s the least expensive to ensure they don’t spend a lot of money in case they find they don’t like growing their own marijuana once it does become legal. We offer a number of cheap seeds. Though regular seeds are often the least expensive, we do have some inexpensive auto-flowering seeds like Auto Gelato feminized seeds and Auto OG Kush feminized seeds. We also offer inexpensive feminized seeds like our Purple Kush feminized seeds and Blue Haze feminized seeds. Any of these are likely a good option for a beginner.

Most people will want to get as much as possible out of each plant. If the number of plants is limited per household once cultivation is legalized, this can be crucial since there can’t be a lot of plants grown at one time. Auto-flowering options that tend to have higher yields include our Auto Critical 2.0 feminized seeds and Auto Devil XXL feminized seeds. We also offer feminized seeds that are high-yield, including Grape Ape feminized seeds and Lemon OG feminized seeds.

Why Should You Purchase Marijuana Seeds from i49?

Marijuana seeds can be difficult to come by in New Zealand since cultivation and possession is illegal. For this reason, most collectors will purchase their seeds online. It can be risky to do this since there are many websites that will claim to offer marijuana seeds but will send out low-quality seeds, if they send any seeds at all. Instead, it’s always a better idea to look for a reputable seed bank to ensure the seeds are high-quality.

Our seed bank offers hundreds of different strains, making it easy for you to find the perfect ones to add to your collection. We only store high-quality marijuana seeds and hand-select all seeds before shipping them to your door. We also have a customer support team available if you have any questions before or after purchasing your seeds. Our goal is to make it easy for you to find marijuana seeds to add to your collection and to offer as many strains as possible so you can find what you’re looking for.

Marijuana may not yet be legal in New Zealand, but the laws are changing, and it is possible that cultivation will become legal in the near future. For now, it’s possible to purchase marijuana seeds and begin a seed collection. If you’d like to buy cannabis seeds in New Zealand, browse our store now and take a look at the hundreds of strains we have available or contact the i49 support team.

Cannabis in New Zealand – Laws, Use, and History

It’s currently illegal to use cannabis in New Zealand. However, the forthcoming cannabis referendum may change this. Under the current coalition government, the medicinal cannabis laws have already been altered, making it easier for patients to access cannabis products; and another law may soon be changed, decriminalising recreational cannabis use.

    • Legal
    • Recreational cannabis

    Cannabis laws in New Zealand

    Can you possess and use cannabis in New Zealand?

    At present, it’s illegal to possess or use any controlled drugs in New Zealand, including cannabis, as stated in the Misuse of Drugs Act, 1975. Cannabis is listed as a Class B drug, which means that it’s regarded as presenting a “high risk of harm”. This means that, unlike a Class C drug, the Judge in court must impose a custodial sentence.

    If caught using or possessing cannabis, the individual may be given a three-month prison sentence, a fine not exceeding $500, or both. In reality, the police force often turn a blind eye to its use, especially in small amounts.

    The prison sentence may be waived if the individual can prove that they took possession of the cannabis to prevent someone else from committing an offence with it, or that they took it in order to pass it on to someone who was lawfully entitled to have it.

    It looked like the law was set to change in New Zealand. In 2017, the government stated that they would be holding a cannabis referendum in 2020, to gather information about the public’s view on decriminalising or even legalising recreational cannabis use.

    Sandra Murray, the campaign manager for #makeitlegal, commented in The Guardian, “We know from polls over a number of years that a majority of New Zealanders support cannabis law reform”.

    However, the referendum was overshadowed by 2020’s COVID-19 pandemic, and polls indicated that public support of legalising cannabis was on the wane.

    Andrew Geddis, a public law professor (University of Otago) commented: “Those wanting to see a yes vote had to convince a reasonable number of people that their previous prohibitionist views were mistaken. At the moment, it doesn’t look like they have been able to do so and time really is running out.”

    It’s unclear whether Prime Minister Jacinda Ardern’s admission about using cannabis in the past will work for or against her. Unfortunately, the proposed Cannabis Legalisation and Control Bill, was defeated with a 50.7% majority.

    Can you sell cannabis in New Zealand?

    Selling and supplying cannabis is also illegal in New Zealand. In the Misuse of Drugs Act, it’s not differentiated from possessing or using; which means the same penalties apply.

    However, cannabis trafficking, or large-scale selling or supply, is regarded as a far more serious offence. If caught exporting or importing the drug, the offender may receive up to seven years in prison.

    Can you grow cannabis in New Zealand?

    It’s illegal to cultivate ‘prohibited plants’ in New Zealand. If caught doing so, the offender could receive a prison sentence of up to seven years.

    Despite this, cannabis is still grown in the country. The leading reasons for growing cannabis were for personal use and for sharing with others. Some grow it for medicinal reasons, as it’s currently difficult to obtain medicinal cannabis products on prescription. A researcher from Massey University found that 16% of New Zealand’s cannabis growers had come into contact with the police.

    Is CBD legal in New Zealand?

    Prior to 2018, CBD was available on prescription only. However, at the end of 2018, an amendment was passed, which altered its legal status. Now, CBD is no longer listed as a controlled drug, and can be purchased and used with a prescription, for up to three months. However, the levels of THC must not “exceed 2% of the total CBD THC and psychoactive related substances content in the product”.

    Can cannabis seeds be sent to New Zealand?

    At present, it’s still illegal to send cannabis seeds into New Zealand via the post. 19,000 seeds were seized by border control officials in 2018 alone.

    Medicinal cannabis in New Zealand

    Prior to the end of 2018, medicinal cannabis products were available in New Zealand; but access to them was limited. Due to the country having no domestic manufacturing facilities, the products (like Sativex) were costly and hard to obtain. Some unapproved products such as Cesamet or Marinol could be approved on a case-by-case basis, but this hardly ever occurred.

    • Better access for terminally ill patients (who can now obtain cannabis without needing a prescription).
    • The removal of CBD from the list of controlled substances – making it freely available for patients who need it.
    • New regulation-making power, establishing quality standards for medicinal cannabis products manufactured or imported into the country.

    Health Minister David Clarke commented: “People nearing the end of their lives should not have to worry about being arrested or imprisoned for trying to manage their pain. This is compassionate and caring legislation that will make a real difference to people.”

    Manu Caddie, CEO of Hikurangi Cannabis Company, was asked by Prohibition Partners about his thoughts on the future of the medicinal cannabis industry. He commented: “We expect 3-4 serious medicinal cannabis companies to be established and licenced in New Zealand over the next two years. We also expect some of the Canadian companies to partner with New Zealand companies.”

    In 2019, the Ministry of Health approved new legislation, which was designed to make medicinal cannabis more accessible; through both domestic production and the relaxing of stringent prescription regulations.

    The medicinal cannabis minimum quality standard, was also introduced to ensure the consistency, and quality of the products available.

    A year later, the Medicinal Cannabis Scheme was finally put into action. It’s anticipated that this will improve availability for patients, and boost the medicinal cannabis industry as a whole.

    The original scheme provided a transitional period for medicinal cannabis products imported into New Zealand before 1 April, 2020, to continue to be supplied until 1 October, 2020. An extension has been granted enabling medicinal products to be supplied without a product assessment until 30 September, 2021.

    In October, 2021, New Zealand is set to host the prestigious MedCan medicinal cannabis summit. MedCan representatives commented: “the event has set out to build a solid foundation of scientific understanding for the advancement of the medicinal cannabis industry”

    Zahra Champion, Executive Director, of BioTechNZ expresses their “goal is to ensure all MedCan attendees come away with a comprehensive understanding about all that lies ahead and how we can best maximise this exciting sector’s success”. She additionally remarks that “with over $100 million invested so far in New Zealand’s medicinal cannabis industry, 2021 is our year to shine”.

    Industrial hemp in New Zealand

    Hemp can be legally grown in New Zealand, as long as the farmer has a licence. This can be obtained from the government.

    Hemp is listed as a controlled drug in the Misuse of Drugs Act, but its cultivation is permitted, as long as THC levels are ‘generally’ below 0.35%. However, the law clearly states that the hemp must not be advertised for “psychoactive” purposes or supplied to unauthorised persons. Only certain varieties can be grown, which are determined by the Director-General of Health.

    A general licence to grow hemp lasts one year and costs $511.11. An additional research and breeding licence can also be obtained, which costs a further $153.33.

    Industrial hemp cultivation is becoming more popular in the country. In 2018, the first Hemp Summit was held in Wellington, where visitors were able to learn more about the industry.

    Political parties and cannabis

    New Zealand’s coalition government (the Labour Party, Green Party and New Zealand First) passed a law in December 2018, which allowed terminally ill patients to use cannabis. They also stated that they would be holding a referendum in the future, to determine whether or not recreational cannabis use should be decriminalised. Their new laws also meant that medicinal cannabis products could be manufactured domestically, which would make them more accessible to patients.

    Chloe Swarbrick, an MP for the Green Party, backed the plans, saying that it showed commitment to addressing the problem of drug addiction, rather than labelling it as a criminal activity.

    However, not everyone supports the Labour Party’s views. Some parties, like the New Zealand National Party (the government’s centre-right opposition) are against the new law. Dr Shane Reti, the party’s health spokesman, referred to it as “lazy and dangerous”, as it will encourage people to start smoking it in public.

    Simon Bridges (also the National Party) referred to the referendum as a ‘cynical’ move; and accused the government of trying to distract voters from other key issues. He also expressed concerns about normalising cannabis use.

Growing feminized cannabis seeds

Cannabis seeds 101: How to grow marijuana from seed

Cannabis is grown from one of two sources: a seed or a clone. Seeds carry genetic information from two parent plants and can express many different combinations of traits: some from the mother, some from the father, and some traits from both.

In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.

If cannabis is legal in your state, you can buy seeds or clones from a local dispensary, or online through various seed banks.

Cannabis seeds vs. clones

For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.

Plants grown from seed can be more hearty as young plants when compared to clones, mainly because seeds have a strong taproot. You can plant seeds directly into an outdoor garden in early spring, even in cool, wet climates.

If growing outside, some growers prefer to germinate seeds inside because they are delicate in the beginning stages of growth. Indoors, you can give weed seedlings supplemental light to help them along, and then transplant them outside when big enough.

Most seeds that you will buy are regular seeds as described above, but here are a couple more types.

How weed seeds work

Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.

Once cannabis seeds are mature, the female plant begins to die, and seeds are either dropped to the ground where they grow into new cannabis plants next spring, or the seeds are harvested for processing into seed oil or food products, or stored so they can be sown in the ground later and become the next generation of plants.

To get the buds found in medical and recreational stores, female cannabis plants are grown in an environment without males—or the males are removed from the area before they release pollen—so the females don’t create seeds. Females can then focus their energies on producing buds and not seeds—this high-potency marijuana is traditionally known as “sinsemilla,” meaning “seedless.”

Some varieties of cannabis can produce male parts alongside female flowers on the same plant, especially if exposed to environmental stressors. These plants are known as hermaphrodites, and sometimes they can self-pollinate to create seeds.

Pros and cons of using cannabis seeds

Check out Johanna’s full video series on how to grow weed on Leafly’s YouTube .

If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.

Also, buying from a reputable breeder or seed bank will give you a sense of what a particular strain will look and smell like, how it will grow, and how much it will yield at harvest.

The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.

Sexing marijuana plants can be a time-consuming process, and if you don’t catch males, there is a risk that even one males can pollinate your entire crop, causing all of your female weed plants to produce seeds.

One way to avoid sexing plants is to buy feminized seeds (more below), which ensures every seed you plant will be a bud-producing female.

You can also minimize headaches and avoid the hassle of seed germination and sexing plants by starting with clones.

How weed clones work

Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”

Pros and cons of using cannabis clones

Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.

With cloning, you don’t have to get new seeds every time you want to grow another plant—you just take a cutting of the old plant—and you don’t have to germinate seeds or sex them out and get rid of the males.

One drawback of clones is they need to be taken during the vegetative stage of a plant—flower is too late—so if you have a small setup with only one light, it can be hard to keep clones alive while flowering other plants, because the two need different amounts of light.

Another drawback to clones is they can take on negative traits from the mother plant as well. If the mother has a disease, attracts pests, or grows weak branches, its clones will probably have the same issues.

Additionally, every long-time grower will tell you that clones degrade over time.

What are feminized cannabis seeds?

Feminized cannabis seeds will produce only female plants for getting buds, so there is no need to remove males or worry about female plants getting pollinated. Feminized seeds are produced by causing the monoecious condition in a female cannabis plant—the resulting seeds are nearly identical to the self-pollinated female parent, as only one set of genes is present.

This is sometimes referred to as “cloning by seed” and will not produce any male plants. This is achieved through several methods:

  • By spraying the plant with a solution of colloidal silver, a liquid containing tiny particles of silver
  • Through a method known as rodelization, in which a female plant pushed past maturity can pollinate another female
  • Spraying seeds with gibberellic acid, a hormone that triggers germination (this is much less common)

Most experienced or commercial growers will not use feminized seeds because they only contain one set of genes, and these should never be used for breeding purposes. However, a lot of beginning growers start with feminized seeds because they eliminate the worry of having to deal with male plants.

Top feminized cannabis strain families

A lot of classic weed strains that have been around for a while come in feminized form. Some popular fem seeds are:

  • OG Kush
  • Haze
  • Afghan
  • GSC (Cookies)
  • Skunk
  • Cheese
  • Gelato

What are autoflowering cannabis seeds?

Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.

Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.

However, a type of cannabis called Cannabis ruderalis, which developed in extreme northern conditions without much sunlight, will begin flowering once the plant reaches a certain age—they automatically start flowering regardless of the amount of light they receive, hence the name “autoflower.”

Pros and cons of growing autoflower

Because they grow and flower quicker, growers can fit in multiple autoflower cannabis harvests into the span of one regular harvest.

Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.

Also, autoflower plants are small—perfect for closet grows or any small grow, or growing outdoors where you don’t want your neighbors to see what you’re up to.

A couple big drawbacks, though: Autoflower strains are known for being less potent. Also, because they are small in stature, they usually don’t produce big yields.

However, potency in autoflowering varieties has increased significantly since their initial introduction, with some breeders crossbreeding the low-THC ruderalis with other more potent varieties.

Tips for growing autoflower marijuana seeds

Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.

Climate considerations

Many marijuana growers start autoflowers early in the season, and at a different time than a regular crop, so keep the season and climate in mind when growing and harvesting—your plants still need warmth to grow, and rain can give them bud rot. Consider growing in a greenhouse to protect them.

Training plants

Because training happens during vegetative growth, for autoflowering plants, this period could be as short as a few weeks, which means time is limited. Try topping your autoflowers after they have three nodes, and stop once they begin to flower. You will want to prune them lightly.

Go easy on nutrients

Autoflowers don’t need lots of nutrients because they’re small and don’t spend much time in the vegetative cycle. They won’t need as much veg nutrients—such as nitrogen—but will need more bloom nutrients.

What are high-CBD cannabis seeds?

CBD, or cannabidiol, is one of the chemical components—known collectively as cannabinoids—found in the cannabis plant. Over the years, humans have selected plants for high-THC content, making cannabis with high levels of CBD rare. The genetic pathways through which THC is synthesized by the plant are different than those for CBD production.

Cannabis used for hemp production has been selected for other traits, including a low THC content, so as to comply with the 2018 Farm Bill. Consequently, many varieties of hemp produce significant quantities of CBD.

As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).

Seeds for these varieties are now widely available online and through dispensaries. It should be noted, however, that any plant grown from these seeds is not guaranteed to produce high levels of CBD, as it takes many years to create a seed line that produces consistent results. A grower looking to produce cannabis with a certain THC to CBD ratio will need to grow from a tested and proven clone or seed.

How to germinate marijuana seeds

Germination is the process in which a seed sprouts and begins to grow into a new plant. Also referred to as “popping,” germination is the very first step in starting your weed grow.

Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.

Cannabis seeds require three things to germinate: water, heat, and air. There are many methods to germinate seeds, but for the most common and simplest method, you will need:

  • Two clean plates
  • Four paper towels
  • Seeds
  • Distilled water

Step 1

Take four sheets of paper towels and soak them with distilled water. The towels should be soaked but shouldn’t have excess water running off.

Step 2

Take two of the paper towels and place them on a plate. Then, place the marijuana seeds at least an inch apart from each other and cover them with the remaining two water-soaked paper towels.

Step 3

To create a dark, protected space, take another plate and flip it over to cover the seeds, like a dome.

Step 4

Make sure the area the seeds are in is warm, somewhere between 70-85°F.

After completing these steps, it’s time to wait. Check the paper towels once a day to make sure they’re still saturated, and if they are losing moisture, apply more water to keep the seeds happy.

Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.

A seed has germinated once the seed splits and a single sprout appears. The sprout is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination.

It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.

Transplanting germinated cannabis seeds

Once you see the taproot, it’s time to transfer your germinated seed into its growing medium, such as soil.

  • Fill a 4-inch or one-gallon pot with loose, airy potting soil
  • Water the soil before you put the seed in; it should be wet but not drenched
  • Poke a hole in the soil with a pen or pencil—the rule of thumb is: make the hole twice as deep as the seed is wide
  • Using a pair of tweezers, gently place the seed in the hole with the taproot facing down
  • Lightly cover it with soil

Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.

Within a week or so you should see a seedling begin to grow from the soil.

Germinating cannabis seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.

This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones or for breeding if you want to create a seed bank of your own.

How to sex a pot plant

Check out Johanna’s full video series on how to grow weed on Leafly’s YouTube .

As we’ve mentioned, cannabis is a dioecious plant, meaning male and female reproductive organs appear on different plants.

Because only female cannabis plants produce buds and you want them to focus all their energy on producing buds and not seeds, it’s important to identify and get rid of male weed plants so they don’t pollinate females. If females are pollinated, it will give you buds filled with seeds, making your weed harsh and unpleasant.

Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.

As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.

If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.

Cannabis plant sex organs appear on nodes, the points where branches grow off from the main stalk.

Males will have round balls—these will develop into pollen sacs, which will release pollen into the air when mature.

Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.

Pre-flowers can initially be extremely small and hard to identify with the naked eye, but you can use a magnifying glass to get a better look.

Can I grow a seed I found in a bag of weed?

Finding a cannabis seed in your stash is not ideal, but we’ve all been there before. Although much less common than it once was, it still happens. Sometimes you’ll notice one when grinding down some flower, or you’ll see one pop, spark, and crackle from the heat of a lit bowl.

These are referred to as “bagseeds” and whether or not you can grow one will depend on where it came from.

Is a bagseed good or bad?

Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.

Seeds can also form in plants with genetic disorders or instability, like hermaphrodites—plants that develop both male and female reproductive parts. Generally, stress and genetic disorders are viewed as bad, so temper expectations with any plant you start from a bagseed.

But sometimes you get lucky and find a mature seed in some really nice herb. Strains like the legendary Chemdog wouldn’t be possible without adventurous smokers planting and proliferating the seeds they found in a bag of kind bud.

So don’t discount bud because it has a seed or two in it. While not ideal, it could be the origins of the next great weed strain.

Ask yourself a few questions to decide if it’s worth the time and energy to grow the seed.

Was the seed found in good weed?

If you don’t like the flavor, effects, or even the look of the bud, then it’s probably not worth growing.

Are you ready to grow?

Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.

Is the seed viable?

For a seed to be viable, it must be mature enough to have a completely formed genetic blueprint, and it must be strong enough to germinate and pop through its hard casing and sprout its crucial taproot.

There are a few indicators that will give you a sense of whether the seed is worth germinating.

  • Tiger stripes—dark stripes on the seed which resemble veins on a leaf are generally good
  • Solid shell—a seed should be able to withstand a little pressure when pinched between your fingers; if it crumbles or cracks, it’s no good

Immature seeds tend to be light in color and have a soft outer shell.

In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.

You might also find a mature seed that has been physically damaged through poor handling, like rough trimming. In those cases, it probably isn’t worth the effort to try and germinate the seed.

But if the seed you found looks decent, you might as well germinate it and see what sprouts.

Time to germinate

Viable or not, there’s only one sure way to find out if a bagseed will grow. If you’re simply curious to learn and not as concerned with the overall outcome, you can plant a couple of bagseeds outside and see what happens.

If you’re ready for a more serious approach, make sure you have the space for a proper garden and pop the seeds to see what fruit they bear.

Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.

Remember, once a seed germinates, the real work begins. Sexing, selecting, vegetative growth, flowering, and the eventual harvest all lie ahead.

How to buy cannabis seeds

Cannabis seeds can be found on numerous online seed banks, but note that it is illegal to bring seeds into the US and Customs will seize any cannabis seeds that they find in packages or on a person. In legal and medical states, you may purchase seeds at a dispensary.

How to Grow Marijuana from Seed

If you’re in a location where cannabis (another term for marijuana; short for the plant cannabis sativa) is illegal, growing it is probably illegal too. Bringing in seeds or cuttings to your location can very well be a felony, and reputable sellers won’t ship to you.

You can probably purchase and grow hemp seeds and plants, which have a negligible amount of THC, but these plants won’t produce the psychoactive effects of plants that contain higher levels of THC. Check with your seller to be certain you’re getting what you think you’re purchasing. If you buy seeds for CBD-only hemp plants by mistake, you can end up being very disappointed post-harvest.

How to acquire seeds or cuttings

You can usually find cannabis seeds for sale at most dispensaries in areas where growing cannabis for personal use is legal. You may also find growers who sell cuttings/clones. You can expect to pay $50 to $100 for a pack of ten seeds. When shopping for seeds or cuttings, read the labels and any other information the manufacturer provides on its website or in its catalog to make sure you’re getting the right seeds or cuttings (the strain) for the plants you want to grow.

One way to get your mitts on some seeds is to collect seeds when you find them in flowers you purchased, or get some from friends if they’re collecting.

  • Feminized seeds: Nearly all seeds sold by reputable companies are feminized, but make sure they are. These seeds are specially treated to grow into female plants.
  • Auto-flowering or photoperiod: Auto-flowering plants are easier, because they enter the flower stage after a certain number of weeks regardless of the light/dark cycle. If you’re a beginner, seriously consider going with auto-flowering plants.
  • Genetic background: If seeds are from a well-established strain, such as O.G. Kush, Bubble Gum, or a cross-breed, the genetic background should be stated.
  • Blend: The blend represents the percentage of the three species — sativa, indica, and ruderalis. All auto-flower strains contain some percentage of ruderalis, which is responsible for the auto-flowering nature of the plant.
  • Yield indoors: The number of grams of bud per square meter of plant when grown indoors.
  • Yield outdoors: The number of grams of bud per plant (after drying) when grown outdoors.
  • Plant height indoors: Shorter than when grown outdoors.
  • Plant height outdoors: Taller than when grown indoors.
  • Time to harvest: Approximate number of weeks after germination the flower should be ready to harvest.
  • Potency: Percentages of CBD and THC.
  • Effect: The type of experience you can expect when consuming product from the plant.

Know the laws about buying cannabis

  • In some European countries, laws prohibit growing cannabis, but seed is legal, which is quite confusing. You’re allowed to buy and eat cannabis seeds because they’re non-psychotropic, but you can’t buy them to grow cannabis. Other countries in Europe, such as Germany, have their own seed laws.
  • In Canada, where cannabis is federally legal, seeds can be shipped across provincial lines.
  • In the U.S., in some states in which cannabis is legal, you can purchase seeds from some dispensaries or other locations to grow plants as long as you keep them in the state. Other states may bar selling to non-licensed growers. Shipping or transporting seeds across state or international borders is illegal, although a few reputable online seed stores ship to individuals with success.

Cuttings are typically treated in a similar manner as seeds in legalized locations. They may be available from some dispensaries or outlets for pick up or delivery with a fee. They’re prohibited from crossing U.S. state lines or international borders. You can buy individual plants and mix and match strains. Prices vary and are often determined by plant size.

Buy cuttings (clones) only from a reputable source who understands proper back-crossing of strains for stability. Back-crossing involves pollinating a plant with one of its parent plants to promote sexual stability, so that when you have a female it won’t hermaphrodite into a male during flowering.

Both seeds and clones are often able to be purchased from commercial locations already in your state.

In the U.S., transporting any part of the cannabis plant over state lines is illegal. This applies to seeds and clones and, technically, even to tissue samples.

How to germinate cannabis seeds

Germinating seeds requires a dark environment that is around 70 degrees. There are many ways to germinate seeds (in soil, in a wet paper towel, in starter plugs) You can also sow them directly into soil in a garden or container, as long as the soil is light and fluffy, so the roots can easily grow down and the stalk can break through the soil. Plant the seeds about 1/4- to 1/2-inch deep and cover them loosely with soil.

Most importantly, seeds need a moist environment; they won’t germinate if they get too dry. You can use a heat mat to increase the success of germination in colder climates.

How to transplant marijuana plants

When transplanting any plant, whether it started from seed or a clone, handle it gently, being very careful not to damage the roots. Center the plant in the pot, and plant it deep enough to cover the root ball completely in soil. If the plant is root bound, you can gently tease the roots apart to encourage outward growth.

Pack your soil or other grow medium down around the roots well enough to support the plant while new roots grow, but not so tight that the soil restricts outward root growth. Water the soil around the roots.

Get Started Growing Feminized Cannabis Seed

Growing your own cannabis for personal use is a rewarding practice—as well as a great way to save money. Today there are quite a few options open to home growers, and cultivating high-quality cannabis is easier to accomplish than ever before.

Commercial growers rely on clones for their mass production, and seed plays a much smaller role, mostly for breeding to create new strains. Growing numerous seeds from a new cross or true strain and selecting the best phenotypes, which are then cloned for large production, is the goal of these companies. For the majority of home growers, however, the opposite is true, and clones play a smaller role. Although cloning is done in home grows, seed reigns supreme!

Most seed companies present a few options for seed buyers: normal seed, auto-flowering seed, and feminized seed. For home cultivators—particularly beginners—feminized seed is a great choice.

What Is Feminized Seed?

Simply stated, feminized seed is seed that will only grow into female plants, which is the goal of nearly every home grower. Female plants, of course, are the sex that grows the lush, sticky, trichome-covered flowers that the grower will harvest and use for medical purposes or recreational enjoyment.

For seed companies to create feminized seed, the process is fairly straightforward. The fact that plants will reproduce when under stress is widely known. In fact, when some female cannabis plants are in full flower but not in the presence of a male cannabis plant, they will resort to self-pollenization by producing a very small number (sometimes only one or two) of male sex organs, which they then use to pollinate themselves to create seed and ensure future generations of their kind.

Known as hermaphrodites, these aberrant female plants with minor male traits are sometimes difficult to detect in a grow with other females. Usually, these “hermies” are an undesirable thing, but since they can be difficult to detect in a large grow, they slip by undetected when harvested, producing good flowers, but flower that also contains a very small number of seeds, usually just a few.

When a cannabis enthusiast discovers a seed or two in an otherwise excellent bag of cannabis flowers, the seeds are a result of a self-pollinating female plant. When germinated and grown, these “selfed seeds” will invariably grow into female plants, because the female that pollinated herself lacks the male chromosome to produce a true male plant. By reproducing herself without being pollinated by a true male, the best she can do is create more females just like herself. For this reason, “bag seed” often grows into plants that produce surprisingly good flower, although these plants also have the tendency to self-reproduce once mature—just like their mother.

How Is Feminized Seed Made?

True feminized seeds sold by seed companies are created intentionally by using select female plants. Feminized seed is not true self-pollinated seed, but is quite similar, created by using more than one female plant.

To create this seed, seed companies will select prime females of the same strain. These females are the best phenotypes of that strain—the best of the best. They’re the stickiest and hardiest females, the ones that have amazing terpene profiles and rich, tantalizing aromas. One of these select females is then stressed to encourage hermaphrodite traits.

There is more than one way to intentionally stress a female plant, but probably the most common method is to apply colloidal silver to the female. Exposing her to colloidal silver will cause the female to produce a fairly robust amount of male sex organs—the pollen sacks seen on pure male plants. The cultivator then collects an ample quantity of this feminized pollen, which is the consistency of fine dust. Dusted or brushed onto the flowers of other prime females of the same strain will result in an abundant amount of feminized seed of that particular strain.

Looking for a Weed Forum? Here are the Top 10

Weed forums are a great thing for cannabis enthusiasts. Whether you’re having a growing problem, or you just need to talk to someone about a new weed game, forums are just the place.

Sometimes, asking the questions and sharing information about marijuana is difficult. This is due to the fact that cannabis is still illegal in many parts of the world. Online marijuana forums allow you to retain your anonymity, and still get the social or educational experience you’re looking for. So, when you’re about to go off searching for the right forum for you, here are a few of the best ones to try first.

Grasscity Forums

There are so many sub-forums on this weed forum, it really doesn’t specialise in anything. Whether you want to get the latest weed merch, learn how to grow hydroponically, or just want to talk about the strain you smoked last night, you’ll find a place to do it here. Even if you’re not here for ganja news, you’ll find lots of interest including sports, music, and more.

The Autoflower Network

There are general weed forums like Grasscity, and then there are those that are super specialised for your needs. The Autoflower Network is the latter. Here you’ll find everything you need to know about auto flowering plants including their history, how to grow them, and more. If you’re all about getting more into the auto flower world, this is the place to go.

Rollitup

Like Grasscity, this weed forum has all the information on cannabis, no matter what you might be looking for. Ask a question about a grow problem you’re having, or learn more about organics. Whatever your pleasure, Rollitup is another place you’ll find it. If you really want to get the most out of it, head on over to “Cannabis Cafe.” Here you’ll find stoner quotes, and even discussions on fitness and well-being.

420 Magazine

Some weed forums are known for how huge they are, and how many members they have. With 420 Magazine, it’s quite the opposite. There are fewer posts here, as well as fewer numbers. But that’s actually what’s so great about this forum. You actually get to know the other members and develop relationships with them. After being on this forum for just a little while, every time you sign on, it’ll feel like entering your friend’s house.

Cannabis Culture

Growing and cultivating marijuana is certainly part of cannabis culture. However, the weed forum Cannabis Culture focuses on much more than that. In fact, you’ll find little here about growing at all. Like the name of the forum suggests, this one focuses on cannabis culture. So, learn how to get involved with activism, or find out where the next cannabis event is near you. Those that know there’s more to marijuana than just growing will love this forum!

Bluelight: Cannabis Discussion

Continuing to move away from strictly growing conversations, there’s Bluelight: Cannabis Discussion. This weed forum is far more into the philosophical than Cannabis Culture. You’ll find like minded people interested in science and the social sciences, and listen to intelligent discussions about all topics cannabis-related. If getting stoned makes you a deep thinker, head over to this forum today.

OZ Stoners

Don’t be turned off by this weed forum just because it focuses on medicinal marijuana and is based out of Australia. Even if you smoke recreationally and don’t live anywhere near the area, this forum has something for you. You can keep up with the latest breaking news in the world of medical marijuana and hear about the latest research.

Cooking with Cannabis

Love edibles? You’ll love this weed forum! Learn all the tips and tricks to make your next batch of pot brownies even better, or to read more recipes you can try next time. What makes this site even better is that it allows users to rate posts. That means with just a quick scan, you can see which posts are going to be most interesting to you.

Ganja Mamas

It’s no secret that many different types of people enjoy marijuana. This weed forum is dedicated to one segment of that population – mothers and expectant mothers. Mothers and soon-to-be mums often face judgement when telling others they enjoy cannabis. This 420 forum lets them enjoy what they enjoy, with no judgement in sight. Learn if it’s safe to imbibe while breastfeeding, how to buy a bong, or just ask questions about being pregnancy. This is a unique and special item in your life, and this forum is here to ensure you enjoy it to the fullest extent possible.

Conclusion

While the above are the top ten weed forums we’ve found, once you start looking into the wonderful world of forums, you’ll find plenty on your own, too. This list is to give you an idea of just how many are out there, and show that if you have a speciality, you also have a forum to match it. So, get out there and start looking! The sooner you find a forum, the sooner you may find some new friends!

I ordered from Herbies and got mine in 9 days. Its not different rules for aussies from seed banks. its just shit luck. If customs never got them they would arrive within 21 days regardless.

Why revive this thread too, its been dead for 6 months if you didnt notice !

Because it showed up in google search so if the threads are dead maybe admin should block them from the search engines using the noindex tag or delete them!! But I’m sure they wouldn’t want to lose any free traffic from google would they? As for Herbies they have advised me that 20 working days starts from the day it leaves there shop. SOS seeds stats there 21 days starts the minute you receive your tracking number! Why the fuck have I been waiting over 5 weeks for a resend then. Customs more then likely have got the seeds! What I’m saying is I’m sitting here waiting for the resend way past the 21 days!

The rules are different for Aussies as far as sos seeds is concerned. They said to me “In your part of the world it has been known for orders to arrive in a 4 weeks after it hits customs so we can not act until such an such date” (took a week and a half just to get to customs) How is that not different rules?? Why don’t they post that on there site so us Aussies know before we order.

Oz post states if you have not received your parcel after 15 working days (3weeks), basically customs has seized your package! So I’m sitting here waiting for a date so they can do the resend.

Royal haze seeds

Royal Haze Auto Feminised Seeds

Royal Haze Automatic was bred by first crossing Amnesia Haze with a Skunk and then crossing the offspring again with auto-flowering strains. It has a life-cycle of just 10 – 12 weeks at the end of which the grower will have buds with that special Haze taste.

In common with other automatic cannabis plants Royal Haze Auto-flowering can be cultivated in almost all environments and climate regions. As a cannabis strain it has the positive aspects of a Haze but without the difficulty and long flowering times and will grow where photo-period Haze plants will not reach maturity before the autumn weather sets in. Indoors it should stay well below 100 cm. in height with yields in the range 300 – 350 gr/m 2 . Outdoors, especially if grown directly in the ground or in large pots, plants will grow as tall as 150 cm. with yields up to 180 gr/plant.

THC production hits 15% with medium levels of CBD (between 1-5%, quite common for automatic strains of cannabis). The effect is strongly focused on the cerebral side with an uplifting feeling. Royal Haze Automatic really does make that Haze flavour and high available to the average grower which is something to be celebrated.

Royal Haze

Royal Haze (or Royale Haze) by Dinafem Seeds is a mostly sativa strain bred from Skunk, Haze, and Northern Lights genetics. Taking after her Haze parent, this sativa inherits a spicy citrus flavor and buzzing, energetic effects that keep you alert and productive throughout the day. Outdoor growers will appreciate her flexibility and resilience even when the temperature drops, although her 10-11 week flowering cycle demands a bit of patience.

An autoflowering rendition of Royal Haze was bred by Royal Queen Seeds, who mixed Amnesia Haze, Skunk, and a ruderalis strain. Its effects are similarly energizing and cerebral.
