Does anyone start their plants outside in a greenhouse and let the natural low light conditions of winter presex their plants? I guess what I am really asking is at what point in the growth cycle can a plant be triggered into changing from veg to bloom, and be changed back to veg once sex is determined?

Whats up BB. Plants will usually show pre flowers at about 6 weeks old some sooner some not at all. Like KADE said your best bet is to take a few cuttings and sex them. Putting your plant into flower them back to veg once sex is determined is very stressful and can cause your plant to hermie. :eek:
