Brothers Grimm takes pride in breeding cannabis seeds that never produce hermaphrodites.


When we release feminized cannabis 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 cannabis seeds were first popularized in the 1990s. However, the breeders who produced those cannabis 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 cannabis seeds.

Over the last five years, MrSoul performed painstaking research that revealed why early feminized seeds generated hermaphrodites. As a result, Brothers Grimm produces 100% female cannabis seeds that have stood the test of time in large commercial cannabis grow operations. These are also perfect cannabis seeds for the small grower who cannot waste space on males.

The dedication Brothers Grimm brings to breeding cannabis seeds was rewarded with a spot in the High Times Top Ten for our Rosetta Stone XX cannabis strain. Danny Danko said, “MrSoul retained the beloved spicy sandalwood aroma and musky flavor of the Jack [Herer] but added resin production, stability, and yield while reducing flowering time. Unlike some poorly produced feminized seeds, these beans pop 100 percent female and grow into heavy plants that need extra support or trellising.”
