SkunkMe1 asks:
what makes a plant go hermie, can anyone explain please ??? what kind of stress ( transplanting, over nuting, tying the fan leaves.... ) ??? wouldnt like to stress my plants. thanks
Basicly a plant can go hermie if it's stressed due to:

Poor light
Under watering - but don't overwater either!
Temperature change - a drop from 75 to 45 for 12 hours can stunt it and stress it
Poor air circulation might do it too...
