flowering

Hey everybody. Just switched my plants over to 12/12 Three days ago. The little buggers are growing like crazy now. A little too fast for my likeing. They are growing about 2-3 inches a day and are getting really bushy. I have 13 plants under a 1000w hps and the plants are starting to get really crowded. Approx how long until they show signs of sex. Just wondering because when i get rid of the males i should have some more room

Watch them closely every day!! You should see signs in 5-7 days give or take.

sweet. They are growing so fast its scary. I know its bad to say but im hoping at least 5 of them are male. I really need the room. They are really starting to cram eachother.
