yea your right, that is one way. The best way to create feminized seeds in my opinion is the best breeders will/should stress the hell out of a strain with a crazy light schedule(like one week 12/12, one week 20/4,next week 10/14 etc) and any other "environmental triggers" they believe causes cannabis to hermie. Once you find a plant that does not herm on you(it is true, they are out there) but more kind of adjust to the light change, you feminize from that plant with whatever chemical(rather than environment) method you choose, almost like finding a great mother for a breeding project. Those seeds will basically be 100% females with out so much of the genetic trait to hermaphrodite. Basically true feminized seeds in my opinion, not just stressin a plant to herm and then sell the seeds off to make money. But most companies do not know of this method(i doubt that) or simply dont want to take the extra, extra, extra time that it takes. I wish I could remember the guys name who discovered this method back in th 90's
