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.

MythPuffers: What’s The Deal With Stems And Seeds?
We all know what it’s like to spend 60 bucks on a disappointing eighth of weed that’s way too stemm-y and chock full of seeds. While it’s not only a hassle to de-seed and de-stem the sub-par product, what you’re left with once your eighth is gone seems entirely useless — but somehow you convince yourself to save it all anyway.
It’s been posited by some potheads that seeds and stems contain no THC, taste like shit, and will make you sick or even infertile. More positive stoners, on the other hand, have faith in the byproducts’ heightening abilities and promote the smoking, drinking, and planting of stems and seeds. Obviously when it comes to drugs like marijuana, everyone reacts to these things differently, but that, my friends, is how legends are born. This week’s MythPuffers is seed-and-stem-centric — focusing on not one but three common myths and questions surrounding the two little things potheads dread most.
One of the more popular ways to rid of seeds and stems is to smoke them — un-ground in many cases. One myth that has spurred from the smoking of these stems and seeds is that they will negatively affect your fertility. What? That’s right — some people believe that smoking stems in particular will lessen a male’s sperm count and damage a woman’s ovaries.
While this may seem ridiculous at face value, according to BBC News, a study at Buffalo University has linked chronic marijuana smoking to a lower sperm count among males. Head researcher Dr. Lani Burkman claims that THC is “doing something to sperm” — something which makes the little guys swim too fast so that they end up getting tired before finishing the job. In terms of female fertility, however, results from a separate study are inconclusive.
While this may not be great news for all the pot head dudes out there, it turns out smoking stems and seeds doesn’t really matter because smoking weed in the first place is what affects sperm count. Therefore — since smoking stems tastes disgusting and your sperm is going to die anyway — why not consider something like stem tea?
Not only is stem tea easy to make but, also, if done correctly ,it’s a great way to get rid of saved stems. While some might believe that stem tea is a sham after learning last week that THC is not water soluble, there are several recipes available on the Internet (like this one) which suggest steeping your pot in something fatty, like milk, or for the hard-core tea drinkers, something alcoholic. Although stem tea will not produce a high as strong as one from smoking — leaves, not stems — there are traces of THC in the stalks and thus drinkers will experience mind alterations if the beverage is prepared correctly.
Now that your stems have been taken care of, what about your seeds? One of the most popular myths — or hopes rather — is that planting seeds found in dumpy weed will grow into beautiful marijuana plants.
It probably comes as no surprise that, yes, by planting seeds found in shake, it is possible to grow marijuana plants. While this seems like an attractive idea in theory, what many stoners don’t realize is the time and effort that goes into cultivating reefer. Especially if you’re living in New York, as a college student, there’s nowhere in the city a plant would have access to proper soil and enough sunlight to prosper — this, of course, is a lot for any smoker. Despite the fact that potheads aren’t of the most responsible breed, if your weed is shitty in the first place, why would you even want to reproduce it?
Of course, there are many other ways to deal with pesky stems and seeds that are possibly more affective and slightly more reasonable than stem tea and planting seeds. Green Dragon, for example, is a notorious weed, stem, and seed concoction that MythPuffers will be investigating in the coming weeks — so stay tuned.
