Is it Legal to Buy Cannabis Seeds in the US?
The short answer is yes. As a seed, cannabis is not considered a drug, making it legal to buy and own cannabis seeds throughout the United States. The laws start to get a bit hazy when the germination process begins. In the United States, marijuana for any purpose is illegal at a federal level. Marijuana is classified as cannabis that contains over 0.3% THC. As of 2021, 36 states have legalized medical and/or recreational use of marijuana. Cannabis-derived from hemp that contains less than 0.3% THC is federally legal across all 50 states. Currently, 18 states have approved home growing of cannabis for personal use, nine of which require a medical registration.
Where To Buy Cannabis Seeds
In states where cannabis is legal, you can buy seeds at a local dispensary or online from seed banks that ship them to the USA. Seed banks typically offer a larger selection. The best seed banks have an established track record of providing high-quality seeds that produce as expected. It’s also a good idea to go with a seed bank that offers a delivery guarantee. Things can get complicated during shipping, especially when shipped internationally. The best cannabis seed banks usually offer free replacements if the package doesn’t make it to its destination.
How To Identify Quality Cannabis Seeds
The quality of your seeds has a direct impact on the quality of your harvest. The most viable seeds are brown, tan, or even black with a hard outer shell and smooth, uncracked surface. An easy way to test the quality of a seed is the “float test”. Drop a seed in distilled water to see if it sinks. If it does, it has a better chance of germinating than a seed that floats.
What’s the Difference Between Regular, Feminized, and Auto-Flower Seeds?
A package of regular seeds will be a mixture of males and females. You will need to sex out the seeds during the flowering phase to discard the males. Feminized seeds are guaranteed to produce buds without running the risk of a male seed sneaking into your crop, turning your sweet buds into seeds. Auto-flower seeds automatically switch from the vegetative state to the flowering stage based on age instead of light, offering a shorter grow cycle with less maintenance.
Now that you know a bit more before you grow, it’s time to find the best seed bank to produce the crop of your dreams.

#1 I Love Growing Marijuana
If you’ve been into the buds for some time, you’ve no doubt heard the name I Love Growing Marijuana (ILGM for short). Located in Amsterdam and California, ILGM came on to the scene in 2012 as a blog chock-full of cannabis education as a way for the founder, Robert Bergman, to share his decades of professional growing experience. After requests for buying seeds came pouring in, ILGM partnered with top breeders and quickly earned its place among the best seed banks. The strain selection is small for a reason—quality over quantity. You still get to select from close to 100 hand-selected strains, all backed by a germination and delivery guarantee. The company also offers a variety of payment options, including bitcoin, credit card, bank transfers, or cash as payment. While the price tag runs a little higher compared to other seed banks, the seed quality and guaranteed germination make it worth every penny.
