Cloning Marijuana: How to Grow Cannabis Without Seeds

Cloning is a bit of a hot-button issue in the world these days. Only as far as cloning humans is concerned though. That’s fair enough considering all the moral, ethical, and spiritual considerations that come along with premise of replicating a human life. There’s no such questions to be debated in the botany world, and cloning plants has been done with much success for decades now. For example, cloning marijuana is an example of this approach to growing plants is a hit with home grow enthusiasts around the world.

You CAN grow a marijuana plant from a seed, but if want the same strain with exactly the same properties, and in some case the same unique characteristics, then you will need to clone it. If you ask an expert about how this process works, be prepared to absorb a LOT of information.

But ask them how to make clones from weed plants and you’ll find it’s quite straightforward. Not as easy as it is to buy marijuana clones, but those of you who like being hands-on with your home grow experiments will want to give cloning marijuana a try.

Cloning Marijuana Guarantees an Identical Plant

An overview of cloning marijuana will explain how it involves cutting of a small piece of an existing marijuana plant and then having that plants develop its own roots . The cut piece of plant will have the same gender and exact same genetic structure as its donor plant, meaning that the plant that eventually regrows itself from the cut piece will too .

Let’s say you have a particular marijuana plant that’s especially healthy and hardy and gives you a bountiful yield of exactly the type of bud you love . Would the sound of having a number of those EXACT same plants sound good to you? Darn right it would, and if you have that plant then achieving this is entirely possible.

Other advantages to cloning marijuana include:

  • Expanding on your crop at no additional cost – asides from basic supplies, making clones is free
  • The ‘head start’ that clones have in comparison to seedlings, meaning in the big picture that they’ll be at their flowering stage more quickly
  • Better choice for those hoping to practice Sea of Green or 12/12 from seed techniques due to clones already being mature and able to be oriented to the flowering stage immediately

Cloning Marijuana: Guidelines

The first consideration you’ll need to have when cloning marijuana is that a ‘mother’ plant will be required to get the clones from. Obviously, choosing a female plant that displays signs of vigor and good health is best. If you have one of those you’ve likely at least mastered the basics of how to grow marijuana, but now you’re about to start down a whole new path.

Here’s a list of the primary supplies you’ll need:

Sharp scissors – You’ll need these to clip your clone pieces from the mother plant, as well as for future defoliation and trimming once your clones have grown into being their own plants

Starter cubes – these are also essential, as they’ll be the homes for your clones while they develop their own roots

Cloning Gel or Cloning Powder – These products are good because they provide a sealant around the cut plant tissue and then supply it with the hormones required for optimum root cell development

Proper lighting – This will be very well understood if you already know how to grow cannabis, but we’ll go over it again briefly in case it’s not. Natural sunlight is best of course, but that’s not possible for many growers much of the time. If that’s your situation, T5 grow lights are the best for clones and seedlings, and especially when suspended 8 or 9” above your clones.

Depending on your situation you may need more supplies, but everyone who’s going to try cloning marijuana will need these four.

Taking Your Clones

Alright, we’re now going to assume that you’ve got your healthy mother plant and all the supplies you need to start. The first thing you’ll do is determine the readiness of your mother plant. There is one basic criteria for this; if the leaf shoots or nodes of the plant are alternating (which means not connecting at the same point on the stem) it is mature and ready for cloning.

Next, soak the starter cubes in water for just a few minutes. No longer. This is important – soak them too long and you’ll reduce the effectiveness with which they’ll promote the clones developing a good root.

Now let’s get down to the hands-on part of how to make clones from weed plants. You want to clip new growth tips on the plants, where there is a new branching and a new top. It is also better to take your clippings from the lower half of your plant, as these leaf shoots have more rooting hormones than those higher up. They will grow roots more quickly because of these hormones.

These growths should be easy to identify being right on the top and often a much lighter green in colour.

Now, with scissors in hand, prepare to make your cut:

  • Use your thumb and index finger to grab the shoot an inch or so below the new growth tip
  • Eyeball your new cuttings so that they will be between 5 to 8” long, so you will be cutting 5-8” below the growth tip
  • Hold it steady as you take the scissors and proceed to cut the branch away at a 45-degree angle
  • After making the cut, use the sharp inside edge of one of your scissor blades to ‘scuff’ up the area just above your cut. This will expose more of the stocks ‘raw’ genetic material inside it and aid in the cloning process

Immediately after this you should place the cutting into a glass of water, and do the same for all cuttings you take. After a short period of time you can remove them and trim off huge lower leaves or clip top fan leaves. Return to the water right after doing so.

Once removed, if you’re going to use cloning gel or cloning powder now is the time. If not, proceed to place your new clones into moistened starter cubes. Press around the bottom of them to ensure they’re well sealed.

The last tip here is to keep your resettled clones out of grow lighting for the first couple of days to give them a chance to settle. No longer than 2 days though. And once you do start to give them lighting, don’t give them 24 hours of it. 16-18 hours a day is better.

Just like that you’ve got no need to buy marijuana clones, you’re now sufficiently in the know to create your own using nothing more than your existing crop and a few supplies.

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.

Growing cannabis at home can be a fun project and a nice way to have your own cannabis plants on hand. You may want to grow cannabis indoors due to inclement weather in your area or due to a lack of green space in your yard. Start by germinating the seeds. Then, plant the seeds in soil or in a starter cube. Once the seeds have been planted, care for them properly so they grow and thrive.

  • After 12 hours, place the viable seeds on a towel.

Wet one paper towel and put it on a plate. Paper towels are thick enough to retain the moisture needed to help the seeds germinate. Place one paper towel under running water until it is wet to the touch, but not dripping wet. Use a ceramic dish or plate, as it will be strong enough to hold the towels and the seeds. The paper towel should cover the dish or plate. [2] X Research source

  • If you do not have enough space on one plate for all your seeds, soak two more paper towels and put the remainder on a new plate covered in a wet paper towel.

Wet other paper towel and place it over the seeds. Make sure the wet towel makes contact with the seeds. [4] X Research source

  • You can try using a heat lamp near the seeds to keep them warm. Do not warm the seeds up too much, as you do not want your heat source to dry out the paper towels.
  • If the seeds become too dry, they could die and never germinate.
  • Be very careful with the seeds as they open. Avoid prodding, pulling, or touching the seeds, as you do not want to damage the roots.
  • Any seeds that have not opened and grown roots within a few days should be discarded, as they are not viable.
  • As an alternative to soil, you can use starter cubes from your local nursery or online. Starter cubes are pre-cut growing pods made of composted bark. They contain a hole where you can place the cannabis seeds and grow them in good conditions. Basic starter cubes are inexpensive and easy to use. [9] X Research source
  • If you make planting holes that are too shallow, the seed’s roots will not have enough soil to grow well. If you make the planting holes too deep, the seed will have a difficult time sprouting.
  • Do not pull or tug at the seeds when you pick them up with tweezers. If they are stuck to the paper towel, wet the towel with water to make the seeds easier to pick up.
  • Do not press hard on the seeds when you cover them, as this can disturb their growth.
  • If you are using starter cubes, pinch the top of the holes in the cubes closed.
  • Maintain a growing temperature of 75 to 85 °F (24 to 29 °C) for the plants so they thrive.
  • Stick to a regular watering schedule so the plants get enough moisture. You can plan to spray the plants in the morning and then again at night so they get the water they need.
  • Grow lights range from $200 to $1,200 USD depending on the size and model.
  • You can get cool white grow lights at your local hardware store or online.

Avoid touching or handling the seeds as they grow. Touching or handling the seeds can damage them and stunt their growth. With the right growing conditions and care, your seeds should sprout and poke out of the soil within five to ten days. [15] X Research source

More than 12 hours of light a day for about 4-6 weeks as the plant matures will be enough. Once the plant is a decent size, you may induce flowering. Switch the plant to a timer of EXACTLY 12 hours of strong light (the more sunlight the plant gets, the more energy it can devote to flowering).

Yes, it is bad for the plant to have water constantly sitting at the bottom of the pot. It could make the roots rot over time.

You can actually find LED lamps made for growing plants online. If you don’t want to bother with that, you can just get a purple light to grow them under. There are many articles online talking about the effects of colored lights on plants.

If you plan on growing short, fat plants, they should be at least 6′ apart. You don’t want the plants rubbing on each other or shading the other plants. You will also want to select a spot to ensure all plants will receive maximum sunlight.

You can start as soon as you see two little leaves budding. During that time, make sure to use distilled water when watering them.

Cannabis thrives in a comfortable room temperature when grown indoors, or a little warmer – not too dry, not too humid. If it feels too hot or too cold for you, it’s probably too hot or too cold for your cannabis plants.

You can’t. You can try keeping it by a window, but you still won’t have much success. Lights aren’t that expensive, look on Amazon.

Yes, rain water is fine for any plant. The use of distilled water is to keep from adding tap water contaminants.

Keeping the plant from “stretching” is simple. Place the lights closer to the top of the plants. There are good video examples on YouTube showing two seeds started at the same time and placed under lights at different heights. The plant with inadequate lighting actually “reaches” for the light, growing tall and thin with longer internodal gaps. The seedling with closer light grows short and squat, with less stem between leaves (internodal distance), which means a better frame and plant structure for supporting the massive buds that you want to grow. As the plant grows, raise the lights with it. (Most folks suggest somewhere in the 16-30 inch range from source to canopy.)

The cultivation of cannabis is considered illegal in many jurisdictions. Make sure it is legal to grow cannabis in your area.

To plant cannabis seeds indoors, first soak the seeds in lukewarm tap water for 12 hours. Discard any seeds that float to the top. Then, place the seeds on a damp paper towel on a plate with 1 inch (2.5 cm) of space between each seed. Cover the seeds with another damp paper towel. Keep the seeds in a spot that remains between 70-80°F (21-27°C), and spray the paper towels with water whenever they start to dry out. The seeds will sprout in 2-3 days. When they do, fill pots or a growing tray 3/4 of the way with loose potting soil that has a pH between 5.8 and 6.3. Press the soil down lightly, leaving some air in it. Then, use a pencil to poke 1 inch (2.5 cm) holes in the soil. Place the sprouted seeds vertically in the holes and fill the holes with potting soil. Water the soil thoroughly and place the pots or tray in a spot that’s always 75°F (24°C) or warmer. Set up a grow light over the seeds and leave it on at all times. Water the seeds every day so the soil doesn’t dry out. The seedlings will emerge in 2-4 weeks. To learn how to use cool white grow lights to help your cannabis seeds grow, keep reading!
