wow, wtf is your problem? do YOU know anything about the science behind making fem seeds? because im pretty sure that if you were to do a punnet square for the breeding of a hermie with a female, you'd have 100% females. So, with this in mind, is it not reasonable to expect 100% females from FEM seeds? and even if he had no fucking clue about the process used, and obviously you dont (you list processes which MIGHT have been used), is it still not reasonable to expect females from his so called FEMINIZED SEEDS?
This guy did not come here to get blasted for his problem, he's looking for solutions, so take your useless comment and go fuck yourself.
As for my advice on the situation, i'd just message seedsman, tell em what happened and if they don't hook you back up then simply dont buy their stuff anymore. simple as that, as frustrating as it may be.
