Mainegrown is kinda right, some strains will show sex early, while still in veg, some might not, and yeah, it takes about 2 weeks or so of 12/12 to find out. This is where cloning comes into play. If you have to space/supplies, you clone each of your plants, get roots, and throw them into 12/12 while the mother of the clones continues to veg and get bigger/heal, then you know which plants are females and which are males.
bonedaddy420 Reviewed by bonedaddy420 on . Noatec's G33K Grow. Long time toke, first time grow. G33K's Log; Grow date 12/03/09 All my research shows the most successful people keep a grow log. I should have written down when I planted the seeds, but I would estimate approx. 2 weeks to sprout in high nutrient coconut husk and worm poop. They have been up about two weeks. Re-planted the girls into a deeper pot to stabilize them. Very long stems before first leaves. Decided I was going to have to bite the bullet and go to the grow shop and spend some money or lose them. G33k's Log; Rating: 5
