Who are the best seed breeders?

As the cannabis industry rapidly expands, the most reputable cannabis seed breeders are contributing to cannabis genetics in powerful ways. Dig deep into it with this list of cannabis seed breeders and genetics companies curated for curious students of cannabis. These seed breeders are authentic, accessible, and they put out all kinds of regular seeds, feminized seeds, auto-flower seeds and bulk seed options. For example, Brothers Grimm Seeds specializes in bulk cannabis seeds for large commercial cannabis companies nationwide.

Unfortunately, somewhat recently the cannabis industry lost some of the best cannabis breeders of the modern age, both SubCool and Josey Wales. These iconic cannabis breeders made significant contributions to the cannabis industry. SubCool was the creator of Jack The Ripper and Space Queen, and Josie Wales created GG4 (formerly Gorilla Glue #4). GG4 to this day is easily one of the top 10 most popular strains of 2021. Josie Wales, thank you so much.
