less potency on female vs reg is just silly. If Genetics are good then the kids will be just as potent.
But the hermie issue is still argued by many. Many very experienced growers here at ic will swear there only hermies after years are from femmed. Many others love them.
I think some strains are much less stable and more likely to herm. Direct S1 seeds from "herman" should never be taken i thought only use the pollen on other stable females.
My own opinion is that femms can be great but there are more unstable strains and more testing should be done. My only herms were from femms but im sure ill be told "grower error". I got males from thseeds mk ultra. got pics too. pure males!
Femminized seeds DO NOT produce males.
Knowing this to be true, there has to be other reasons for what you saw with the MK ultra. Be it a hermaphrodite you saw, or perhaps not given the seeds you thought you bought.
I too had a male grow from supposed femmed seeds, but I let the breeder know that I know better than that...and they sent me the proper seeds and an apology for fucking up.
There will be NO males come from a pack of actual femmed seeds.
Lots of people swear to things...because it requires very little of anything to swear.
