It also reduces the risk of having a stray male sneak into your crop—just one male can pollinate a huge crop, causing your females to focus their energies on producing seeds instead of buds.
Marijuana seeds are considered a cannabis product just like flower, edibles, and concentrates. Their legality depends on which state you live in. People living in states with adult-use legalization can buy, produce, and sell seeds within their own state, but seeds can’t cross state lines. People living in states with medical marijuana legalization can only buy seeds if they have a medical card.
An inexperienced breeder might cross a male and a female one time and sell the resulting seeds as a new hybrid strain, but professional breeders usually put their strains through several rounds of backcrossing to stabilize the genetics and ensure consistent plants that reflect those genetics.
Many world-renowned seed banks are overseas in the Netherlands, the UK, Spain, and other countries where cannabis laws are less restricted. Seed banks provide seeds from a variety of different breeders.
The first couple months of the year is a great time to start planning your cannabis garden to get a head start on the outdoor growing season, which roughly runs from March to November, depending on where you live.
Some strains are easier to grow than others because they are more resistant to mold and pests, so if you’re new to growing, you may want to try an easier strain to start.
Is it legal to buy marijuana seeds?
If you want six total cannabis plants to harvest for buds and are growing from regular seeds, start with about 4 times as many, or 24 seeds. Some won’t germinate and some will turn out to be males, and then you’ll want to discard down to the six best phenotypes. If growing feminized seeds, you can probably start with about twice as many seeds in this case (about 12); a couple won’t germinate, and then discard down to the six best phenotypes.
Seeds can come feminized, meaning you can just put them in soil and start growing for buds. These seeds are guaranteed to be bud-producing females and growing them cuts out the step of having to sex out plants and discard the males.
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.
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.
What are high-CBD cannabis seeds?
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.
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.
Time to germinate
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.
