When we release feminized seeds, we have done enough work to ensure they are all female with zero hermaphrodites.

Brothers Grimm founder and breeder, MrSoul, is a respected and frequent speaker at major cannabis events, and his “Feminized Seeds” seminar series is hugely popular.

Feminized seeds were first popularized in the 1990s. However, the breeders who produced those seeds did not present an understanding of how feminization really works.

They frequently grew hermaphrodites and did not know why. Naturally, this caused a bad reputation for breeding feminized seeds.
