... with pix of those lovely little girls! I assure you, they're /not/ boring

Sux if you don't have enough lighting, but yeah, moving 'em around a bit so they all 'get their share' of the 'good' one is a good idea. Imho, making 'em dance is a very early form of LST, and therefore a Good Thing (tm).

If you're gonna go with the more linear (rectangular footprint) tent, then tube-style flouros make sense. If with the more 'square' footprint one, I'd reccommend CFLs, but in either case, add as big an HPS as you can to pound de buds. 600w would not be too big (with a good airflow), and 400 would fit well.

Have a buddy who used a 1000w MH with 8x4' Sunblaster flouros in vertical array around his tent (2' x 4' x 6' tall), from start-to-finish, and his stuph was killa. Verra killa. Please know that he had the MH in a LARGE cooltube.
