i'm not sure supressing the production of ethylene would be that stressful. i know its not what the plant normally does, but is it the equivalent of sleeping on the wrong side of the bed stressful, or is it the equivalent of being sprayed with mace in the genitals stressful? big difference there.
i have grown mostly femmed in the last year, and had two herm out of 15, and both of them quit after about 10 days or so and went back to work. i grew 12 regs and picked out 3 females to keep and two of them hermed. one hard, had to get rid of it, the other i picked a few nanners off of then it settled down. i'm not at all convinced its the stress that causes it, i'm thinking parental genetics has a lot to do with it.
