@surfinc It's your grow, and whatever you want to learn to do as part of the hobby is all good. But, if you do make them, don't share them around, don't pass clones to your friends. Keep the fems in your own freezer, then they don't make it in the pool. And don't use the chemicals. Use light interruption, heat stress, underwatering, natural stresses that will cause a plant to herm. The pheno that takes the longest and is the hardest to get to herm is the one you want and will provide you a higher percentage of stable phenos, if you're going to pursue this
But if you really want to push the boundaries, make regs and pheno hunt further generations that are tailored to your personal grow. Take the time to learn more than hunting the girl, learn how to hunt the proper breeding male too. Anyone can stress a plant to make it herm and it's a process that is done in one flowering cycle. The pheno hunt for proper female/male pairing takes much longer, often years, and will teach you so much more about the subtle nuances of our plants.
And yes, feminized seeds are a "caving in" of seed makers to market demands. There's lots and lots of money to be made in fems, especially when they have the false value of them all being "female", and they mark them up according to this perceived value. 20 years I spent in advertising, I know all the tricks to get a buyer's money in the clients pocket, and creating value is the oldest trick in the book.
