earliest sexing!!

what is the earliest in terms of plant life (eg. 2 weeks, 10 weeks.etc.) has anyone been able to tell the sex of a plant?

you can only tell the sex forshor when you begin flower

Some will preflower, but usually takes at least a month and is rare. I have one she showed at about 4 weeks but none of my other plants showed anything. I'm doing 24/7 time. I got a pic in my gallery of female preflowers if you are interested.

you can put a branch of the plant in 12/12 (cover it with something) and that part will bud and show sex while the rest of the plant stays in veg

thanks for the info brethrens!! word!! wash your balls!!

I sexed mine about 3 weeks after they sprouted. It actually was an accident. I was doing 10 hours natural sunlight, 8 hours 400w MH and 6 hours darkness. All 4 plants (2 master kush and 2 early misty) showed sex. 3 were fems. The lone male showed its balls and it was only about 4"! I have them under 18 hours MH now to revegg.
