I'd devote more floor space to your flower room than to the veg area.

1) If you're gonna be growing from clones, you can flip them to 12/12 as soon as you want. I dunno, 4-6 weeks? Depends on lotsa things, strain, how big you want them to finish, etc. You can actually flip 'em about as soon as they have roots. (Check Oldmac's grows for that kinda operation.) They're gonna have to spend 7-8 weeks minimum, (again, depending on strain) in the flower room. Sativas may take considerably longer, dammit.....

With equal space devoted to veg and flower, the plants are gonna start piling up waiting for a space in the flower room, just 'cause they stay in there so much longer. I've heard of <cough> continuous grows with 10-11 plants in bloom being "fed" by 4-5 in veg. :thumbsup:

2) your veg plants can be moved around a bit for space, if necessary. You could even veg a few in the living room under T5 accent lighting, if ya had to. I think they're pretty. You don't need a "special" place for them like your plants in flower, which need total darkness for 12 hours every single day.

Need to ventilate a vegging plant? Just open a window. Need to ventilate a flower room? Now you need light traps, ductwork, etc. Little more critical setting up the bloom room, IMO.

Just my .02, hope it helps. Hermie
