If they are over two months old you may flower them. If they are three months old, they are there. Not all will have white hairs. Males will not have white hairs. If they are three months and have no white hairs, prob are males. Flower them. If the grow balls they're males.
I'm not kidding, they grow balls.

Tricks to force sexual maturity of plants Hi, I got 3 NL's on the go under 400W HPS but tiny cupboard and no ventilation other than keepiong the door open when the lihgt is on. Also using miracle grow :S I dont want people commenting on my conditions - they cheap and get the job done for a fair yield. Anyway, Flowering before the plants have shown their sex results in poor yield/longer flowering (apparently - certainly makes flowering longer). These seeds are feminized - i wanna force them to go so i can flower them now. Rating: 5
