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.

What if my seeds are burried too deep?

Hey so I planted about 10 seeds 5 days ago, all were rooted aleast 1/4 or an ich to a 1/2 an inch.. So when I planted these seeds, I planted them all about 1 inch to 1 and a half inch down in the soil. 5 of the seeds are under a 24 hour light in my closet and the other 5 are in sunlight in a window that should get about 12 hours of sunlight. None of them have sprouted out of the ground yet, and I actually dug up 2 and I could not find the seed. wtf. What I am afraid of is that they all have sprouted the leaves but then died because the leaves were sprouted underground. I am not sure if this a possibility, or if plants are smart enough to keep growing till they break ground. So are my plants going to die or will they just not have enough energy to fully sprout. Please give any info possible thanks!

The leaf won’t grow and die under there an inch ismt all that deep..i put mine like pencil eraser deep. ..You should make sure the seeds are developed fully before planting..white seeds tend to not grow..immature. .Tiger striped and brown with black spots are what to look for. plant seeds and usually two to seven days and they’re all up. what did you plant em in?
Some people like to put the seeds in a wet paper towel in the dark and once they pop open they get planted

The rule of thumb for planting seeds is: four times the width of the seed. So plant MJ seeds about 1/4″ deep, with no light cuz they don’t need it yet and you run the risk of drying out the soil and killing the little sprout before it even pops up.

the best thing to do if you have nice seeds , put them in wet paper towel keep it humid , after 1 week the first leaves will come out and thats the time you put it in soil

OH MAN. Very common rookie mistake. You are not the first to say that, heck, I’ve done it myself. Trust me, those seeds did not disappear. And by digging around, you dry out the soil at the top, and if you shifted the seed to the top, it will never grow because of no moisture, hence you think it’s a bunk seed, or just vanished. Give up to 7 days. And seeds that get planted an inch too deep WILL make their way out. They literally reach out of the soil looking for light. I speak from experience.

What Dannyboy said is true. And most importantly, BE PATIENT. It’s not uncommon to have a seed suddenly show itself over a week later.

i’ve had a seed pop a month later lol. its shell was too thick and it too a long time to get moistened. if you want the to pop earlier soak the in water for 12-24hrs

Yes I germinated them, I soaked them in water and then put em in paper towels till the root was sprouted about maybe a 1/4 of an inch out, some were a little more, some were a little less. All I know is I buried them way more than a pencil eraser. Like i buried them an inch deep maybe more. a little more than a pencil eraser (considering i used a pencil to make the hole for the seed, hahah. None have sprouted (there are 10) its been 5 full days now.

Luckily when I inspected them I only shifted through 2 of the seeds soil, so I would not mess them all up. I am keeping the soil wet, pretty much when the top layer begins to harden I spray water.

So funny thing is about 20 minutes ago when I checked the little suckers NONE were sprouted AT ALL. and now I go back to add water and wtf. hahah 2 little mofo seeds are NOW popped out of the ground. very happy! I hope the rest come soon!

man just be patient !! all seeds have their time to sprout out. i usually throw away if its already past 10 days. but i always mist the top of the soilless to keep moist all the time, till you see sprout.

Will a 250 watt mercury bulb kill it. or no? Because I know mercury bulbs give off a lot more lumens. Its a Mercury or a mercury HID bulb.

Never heard of mercury bulbs.. MH & HPS are the best but you should buy both MH for veg & HPS for flowering
which aint cheap i would go with T-5 lights which are high output lights and work very well i paid 200.00 for my set.

Mercury vapor is mostly green light. Which is mostly reflected by green plants.
