In states with adult-use legalization or a medical marijuana program, you can buy seeds within your own state, either at a dispensary or through a specific seed company’s website.
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.
How to buy cannabis seeds online
Because US federal law still prohibits cannabis, it can be hard to find information on seed banks and breeders. Breeders who have a long history and positive reputation are usually a good place to start. To get an idea of what well-established breeders look like, check out:
Cannabis seeds usually come in a pack of 10 or 12 seeds and start at around $40 a pack and go up from there. Some high-end genetics can run between $200 to $500 a pack.
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.
If you browse through seeds being sold at a dispensary or an online store, you will immediately see feminized seeds, regular seeds, and autoflower seeds. A vital part of understanding how to buy cannabis seeds is understanding the differences between these categories that refer to the sex or maturation process of the seeds.
At the same time, there are some potential drawbacks to buying seeds online. For one, some weed-legal locations, including the US, still outlaw buying and shipping seeds across state or national borders. There are also issues of reliability. If you want to do business with an online cannabis seed bank, take some time researching the company. Make sure it’s reputable and has good customer reviews.
When you’ve decided which strain to grow, do a bit of research to familiarize yourself with the unique cultivation needs of that strain. While there are general guidelines for growing any type of cannabis, each strain has its own specific needs. Some strains do better in specific parts of the world or climates. Growing a strain that is well-suited to your climate will make it easier on you and the plants while giving you better odds of a successful harvest. If you aren’t certain what strain you want to grow, you can always give mixed packs of seeds a try, though it may be difficult to replicate any successes.
However you go about buying cannabis seeds, you need to plan ahead. In many ways, successful germination and eventual harvest depend on getting the right seeds upfront. Fortunately, the cannabis industry is now offering an incredibly broad selection of seeds to choose from. Here are some of the most important factors you need to think about to ensure that the marijuana seeds you buy will meet your needs and objectives.
In many ways, buying high-quality seeds is very much like buying other items related to cannabis. Even in places where weed is legal, seeds are generally considered cannabis products the same as flower, edibles, oils, and anything else coming from the cannabis plant. For that reason, always pay very close attention to the legal status of marijuana seeds in your area.
Buying seeds directly from a brick-and-mortar shop gives you the benefit of being able to talk to an expert before making your purchase. Make sure the dispensary you’re buying from has employees who are experienced with the growing process.
The difference between male and female seeds is important for growers. To get big harvests of smokable buds, you want only female plants. Male plants, on the other hand, can cause a lot of problems as they will pollinate the female flowers, which makes the buds produce seeds. While some people argue for the usefulness of male cannabis plants, most growers are primarily interested in big, seed-free flowers from female plants.
If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.
But if the seed you found looks decent, you might as well germinate it and see what sprouts.
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.
Transplanting germinated cannabis seeds
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.
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.
If cannabis is legal in your state, you can buy seeds or clones from a local dispensary, or online through various seed banks.
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.
