light poisioning a fem'd seed (theory and questions)

so ive looked at a few other articals on here and have come to the conclusion that as long as the offspring seeds are being used just for bud not for furthering the genitics it ok to light poision a femd seed to get it to herm and create fem'd seeds
so i have a reserva pravidia sour kush aka headband feminized seed im am going to grow out i also have a male from some unknown strain so heres the dealio the headband will by the mother and i am planning on cloning a few times i could either a.) pollinate a clone of the headband with male pollen and get femal and male seeds with a couple herms in there im sure but i could get male and female seeds and b.) i could take a couple clones and light poision one of them so that it creates male parts that have female genes thus resulting in feminized seeds because the only cromozones the plant has are female then just use those beens to make sensi (which im sure there might be a few bananas but in which case those should in theory also be feminized because the male cromozones were not passed down i think) but i am wondering if any one has tryed light poisioning a femanized seed and what the out come was???? once my current grow is finished hopefully with in the next month i will be trying both of these methods and documenting it on here so there is a documented outcome to both of these methods

i think what you are trying to do is back breeding??? but yes an interesting theory but i think a femenized seed has corrupted genes and are very unstable when u breed them exspecialy when breeding with its self

well we shall see then huh lol
