Hey, don't beat yourself up over having a hermie, if it crops up, then it's in the plants genetic make up to do so. Stress can induce it, but it first has to be in the plants nature, as in some strains of afghan. I personally throw out my hermie seeds, but have read they're used in the first step of the process of breeding feminized seeds (?) Don't know how accurate that info was, can't believe EVERYTHING you read. Look on the members list & find 'Cannabis-seeds'. I've got some really useful info from him. Good luck & have a happy!

BTW. Maybe nothing stressed it. Sometimes one will pop up just because it's in the genetic make-up, but before you toss those seeds, ask someone from a seed bank. If the info I read was correct, you might be interested in trying your hand at breeding your own femseeds.
