I never realized people were breeding out the fem seeds. We tried it in the 2000's and every time the resulting seeds came up with lots of deformities and herms. So we've been telling people for years "DO NOT BREED WITH FEM SEED!". Although getting online now I see many others disagree with that. I read they used stress in the early days and now with chemicals to make the fem seed. Not sure if that's true or not but I would never breed with them again. Personally, the males always seem to grow the fastest and with the most vigor, very desirable traits.
