We aren't talking about taking a genetic line with a predisposition to hermaphrodite tendencies and then selfing them. Thats just bad practice and if you sell them i think its unethical. You can self even the most stable genetic lines, and the act of doing so does not cause the offspring to have that tendency. Shit in equals shit out. So basically good breeder plus good genetics and fems are absolutely fine. Anything involving bad genetics or a bad breeder and all bets are off regardless of whether its regs fems or autos.
Good breeder good genetics -
A stable strain that is what I expect when it grows, not an indica strain that throws sativa phenos which are harder to grow than indica and see me mess up and complain of Herms.
Genetic line pre disposition to Herm and selfed -
You mean every strain from the wild, everything and every genetics possible. Why do you think we have this problem, millions of evolutionary crosses were not going to undo in fifty years of trying to breed it out.
Shit breeders -
Myself, others, we chuck pollen, self, bad cross, unstabilize strains. Still not getting pollen from bad breeding or producing Hermie traits and lines. Behind the backs of some fancy bank we produce the same unseeded bud without their expert breeders.
Skill -
You can give your best Herm resistant strain worked all your life never had a nana or sac to a newbie and he will Herm it. Nothing you say makes any sense, lots of newer growbies Hermed some stable genetics only this week. This one point always stands out.
