Should I flower?

I'm on three weeks and a couple of days of veg. The Northern Lights plants are 1 foot tall now. The problem is my space is 2X2 with a five foot ceiling. The plants are starting to crowd each other in this small space and are fighting for light. Once I sex these plants and toss a couple of males I won't have this issue anymore. Should I go ahead and flower now? What can I expect for total height?

The plants will at least double during flowering ... and they will continue to spread out too. Most of us closet types learn through trial and error when to enter the flowering cycle. After you've grown a couple of jungles, you'll get the drift of things. *lol*
