Don't Agree,I know reg grown plants can also turn hermie,But Feminized are far more Likely to turn.There is a bigger margin of error with reg plants ,I have Kept Reg grown mothers for years a few for near on 10 year ,A feminized seed is Produced by stressing that female Reg female to produce male Pollen,either by stress caused by something you do to force this in the room,Or Silver,But I have kept Feminized mothers ,and they have been along side reg mothers ,they turn on you, far faster than a reg would.If you look into,Clone Production over seas where its legal ,than most of these clones are from reg grown Mothers,Not Feminized.They have come a long way since when i first started using Fem seeds,They are far more stable more hardy,and less chance of them turning on you has fast.But saying that i would much rather keep a female i have selected from a Bunch of males and females ,pull the males,Grow the females out and keep what one i like best ,But Clone before you flower ,and that 2nd Generation clone would become my mother ,that i can keep for years ,just re cloning and vegging back up after a time.I'm not saying that you can't keep Feminized mothers,I have not done that in years .But saying that i'm in the Process of doing just that with the new feminized seeds i'm doing at the minute..I will have near enough, full Feminized mothers .FLemon Cheese ,Critical Sour Diesel ,Exodus Cheese ,And also Will be doing Blood Orange ,The Tangie Pheno,But that will be a Reg seed .In hopes i can Find that Special Pheno in the few seeds i have of it .
