The law is the first thing to take into consideration when planning to grow cannabis. Before doing anything else, double and triple check the laws in your area related to purchasing cannabis products and growing weed at home. This is important because the legal status of both cannabis products and home cultivation will dictate where and how you can buy cannabis seeds.

How marijuana laws affect buying cannabis seeds
If you live in a state where it is legal to grow weed at home and there are not many restrictions on home cultivation, then you’ll likely be able to buy cannabis seeds directly from your favorite licensed dispensary. In some cases, you may also have the option of buying from a brick-and-mortar or online retailer.
Another question to ask yourself is whether you want to be an indoor grower or an outdoor grower.
Remember, seeds must be germinated before planting and there is no such thing as an iron-clad germination guarantee. Always plan on a certain percentage of seeds failing to germinate or growing into weak, unviable plants. So plan on purchasing more seeds than you think you will need. As a general guideline, assume that at least 25% of the seeds you plant will, for one reason or another, not make it to harvest. For best results, buy and plant 25% more seeds than the number of mature plants you want to produce.
Seed banks exist outside of the US and can sell them for “souvenir purposes,” but it is illegal to bring seeds into the US and Customs will seize any cannabis seeds they find in packages or on a person.
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.
Where can I buy cannabis seeds?
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.
If you grow some seeds and like the results, try growing another strain from that same breeder and see how it goes.
Autoflower plants change from the vegetative to flowering state with age, not the changing of their light cycle. They have a short grow-to-harvest time and can be ready to harvest in as little as 2 ½ to 3 months from when you put the seeds in the ground. The downside is that, typically, they are less potent, but autoflower seeds are great for people who want to grow cannabis but don’t want to spend a lot of time doing it.
