    I forced mine at about 5 weeks...they are gonna need some time of more than 12 hours of light to get going good...

    If you go 12/12 and get a male then that sucks, if you go 12/12 and get a female then you've potentially lost a large amount of harvest. The best way (not the fastest) is to take a clone from the plant at about the 30ish day mark and put it 12/12. And just order fem'd seeds and :P

    nah go look up all the 12/12 pages, they can get going on that it's just a loss of a lot of growth time.

    2-3 weeks, mine took a little bit more then 3 weeks but thats how long it takes.
    plants dont turn out small if you 12/12 from seed, I grew mine in a 1gal pot then when it showed sex and was rootbound enough I replanted it into a 3gal pot and it exploded.

    I'm up to 15 days. I vegged for about 3 days so I pretty much 12/12 from seed.
    Edit: still no sex.
    You can check out my op in my signature. I hope it doesn't take much longer..... 15 days for sex is torturous. Lol

    I only grow mine 12 12. In a 3 gallon pot I got 4-5.5ft plants. I saw preflowers at 29-31 days confirmed flowers a week later.

    Has the formation on pic one blossomed any pistils yet? Pic two shows stipules, not pre-flowers.

    Yes a plant in veg will show sex by preflowering when they become sexually mature. Its strain dependent and can be anywhere from 3-6 weeks or even longer in some cases. You often have to look very close to see the preflowers. I like to check the fourth node from the top of the plant. Seems that is where they show first.
