Yet another flowering question

Hey folks, I think I've read myself straight...Check out my babies and let me know when ya think I should trigger flowering. I thought that the plant would show sex...then veg' for as long as possible. But I'm reading a lot about folks just triggering flowering by just going to the 12/12 light schedule. I'm indoors under a 400 watt hps and two 3000 luman CFLs just under a month in. Started with feminized NL x BB and Fox Farm Oceans Forest. Give me your advise...Please

well there all going to be female (hopefully!) But it depends on space. Get them all in at least 3 gallon pots. They will strech roughley 3 times the height they are when put into flowering, so to maximize yield, veg untill it has taken up a third of the vertical height then force it into flowering if it hasn't allready shown pre-flowers.
