fem seeds are crap, way too sketchy of a process with terrible results the majority of the time. Dont waste your time producing or buying fems, its just a disaster waiting to happen. I have produced and grown fems both successfully and not, and the general consensus between the people I know is that they're not worth buying, or producing anymore. Better to get 3 - 5 females in a batch, clip em label them and flower them out, and keep only the two best sets of clones for mothers.
