Top 5 Seed Banks Online
4. Seedsman – Best for specialized strains
Seedsman offers an enormous amount of licensed breeders, all listed in alphabetical order. For those on the lookout for a specific big-name breeder, Seedsman probably has it. Popular strains available include Sour Diesel, Skunk, and White Widow, along with a great selection of autoflowering and feminized seeds.
Sometimes seeds are confiscated, but that’s why most companies offer a delivery guarantee, with a paid tracking charge. Larger packs may also be separated into multiple packages arriving, since a large pack of pot seeds would be difficult to hide in one small gift item.
Though the site is registered in The Netherlands, the company is actually based in the U.K. Customers can expect a rewards program, multiple payment options (with discounts for Bitcoin and wire transfers), and free seeds.
Shipping is quick because of the proximity to the US and many different strains have been collected from all over the world. But Sonoma Seeds’ fast shipping to the U.S. is what impressed us the most… a promising company to watch.
Do all marijuana seed banks have multiple payment methods?
While many companies do seem to be a Canadian seed bank store, I Love Growing Marijuana and Rocket Seeds are both based in the United States and have a reputation for high-quality seeds.
That’s about as discreet as you can get.
Try Amsterdam Marijuana Seeds for the free gifts and keep coming back for its reputable seed bank brand, and from the city that started the whole craze. As a wise stoner in a pulpy black suit once said, “You’ll dig it the most.”
12. Sonoma Seeds – Most Promising New Seeds Bank
The shipping time to the US could definitely be better, but if you’re looking to support a new Spanish cannabis seed bank that’s making a name for itself in the scene, you should definitely give Herbie’s Seeds a try.
You could send Bitcoin, Paypal funds, or even a money order through the mail and get your seed within a couple of weeks. Shipping is same-day and faster-than-average, with a dedicated customer support line.
If you buy a packet of regular seeds, they’ll come with a mix of males and females. A lot of cultivators prefer to grow these because they haven’t been backcrossed—essentially inbred—as much as feminized or autoflower seeds. You’ll need to sex out the seeds once their reproductive organs show during the flowering phase and discard the males—because they don’t produce buds and will pollenate females, resulting in seeded flowers.
Breeders talk about “unstable genetics,” meaning that a seed’s origin is unknown. Make sure that when you buy a packet of seeds that it or the breeder who produced them can list where the seeds came from and how they were crossed and/or backcrossed to get the seed that you hold in your hand. If you can’t get a seed’s history, it could be anything and the result of poor breeding practices.
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.
You can also do some research and find an online grow journal that details the whole growing process of a specific strain from a particular breeder. Through these, you’ll be able to look over another grower’s specific notes and see pictures of the final results.
Make sure to always stay within your state’s legal limit of growing plants.
When you grow any amount of seeds, a percentage of them won’t germinate, even if you get them from a reputable breeder. Always count on a few not germinating or dying off, or roughly 1/4 of the total you put in the ground.
Which strain should I grow?
If you grow some seeds and like the results, try growing another strain from that same breeder and see how it goes.
