I read about this once. I believe one method of creating good, relatively stable feminized seeds is to take a batch of females and stress them by bouncing the light cycle around (exactly how drastically they change it up I don't know) and the ones that turn herm get tossed. The ones which resist the stress and don't pop any nanners get treated with some form of chemical, ie. giberellins, ethylene, abscisic acis, etc. These chemicals cause stress and almost always cause the female to grow male flowers. This pollen is harvested and then usually crossed with another female to produce feminized seeds. If done properly, there is supposedly not much more chance of getting a hermie than from regular seeds. The hermaphrodite gene is pretty inbred in all cannabis so there is always a chance of getting hermies. Nobody can predict all the various combinations of genes and possible phenotype expressions. The possibilities are almost endless.

Sorry, I don't remember where I read about this or how accurate my recollection is so take it for what it's worth.
That is one of the chemicals that can be used. There are quite a few different ones which I've read about. Not sure which ones work the best and why.ive read similar info. accept i read you use STS to genetically mutate the female to produce male parts. it pollinates its self. being that the plant was chemically altered, the female plant still only contains female chromosomes, so whatever seeds are produced will be female.
also ive heard you give them 24-0 light cycle for like 22 days until you do the STS treatment..
STS is silver nitrate and sodium thiosulfate....
hope this helps.
