i'll do it for you adjor, i got this..
guitar man, fem'ed seeds aren't made by stressing a girl to make male stamen, but rather by the introduction of a chemical, such as collodial silver..
when you spray an otherwise happy and healthy female plant with c.s., it encourages the plant to grow male staminate flowers instead of pistils where sprayed.. once the stamen grow and open, you can then either take the pollen and use it on a female flower on the same plant, which creates what is known as s1's, or selfed 1's for obvious reason, or you can use the pollen on a separate female, creating f1s..
the introduction of the chemical does nothing to the dna of the plant.. so long as the plant you started out with was stable, meaning not hermie prone, then all of it's offspring will also be stable, ie, not hermie prone.. if the mother plant wasn't stable, then obviously the same will be true with it's offspring.. pretty much garbage in, garbage out..
this holds true for what ever form of seeds you make, regular or feminized.. the fem process does nothing to introduce a hermie trait if it wasn't there to start with.. if you start with hermie parents, you'll more then likely get hermie offspring as the hermie trait is dominant, and shows in the offspring.. again, this is true with either regular seeds, or feminized seeds..
