hey J.. I had Hermie issues my last run, and its totally possible to seed a crop, in a tent or small room, with only a few Mae flowers that open. I was literally gloving up, and plucking with wet tweesers, before they opened, for 2 hours a night, for a week, on a certain strain. Keep a CLOSE eye on things, and if you start seeing little yellow banana looking things on your buds (and look real close, they are easy to miss) then you will have a battle on your hands. Especially if they start opening. If you can catch them before they open, you are good. They like hiding too.. I would usually find some tucked right in where the buds met the stalks, and didn't get any light. If they are opening in places like that, the pollen is usually pretty confined, and used up before it spreads. Also, don't be afraid to manhandle your buds with gloves on, and bend open buds at every node.. No joke dude.. If they go undetected, you will have really seedy buds.. Especially if its in the genetics, and not by stress.
