A femmed plant will hermie on you in a couple of generations due to the instability of the methods used to make it a fem seed.
Sorry I just cant agree with that statement, instability? whats that? IMO thats simply not true, inbred breeding is a viable way to create a true breeding line. Lots of strains today have been created thru inbreeding, and its one of the fastest ways to get a homozygous strain. If the fem seeds you aquire come from a good breeder, and you self it a second time(S2) and then backcross to the same m/f strain then your really on track to having something. There is alot of disinformation around about "female" seeds. If you want to breed with a "female" seed you really need to know how the breeder worked the feminization. And most importantly if he stress tested the mother. And where the line originated.
