This is what I have decided to do:

1) grow two plants in a indoor closet with (3) 23w cfl per plant (about 4500 lumens per plant) and have (1) central 42w cfl.

2) upon completion of seeding and vegging I will use 175w hps in that same closet for flowering.

Sound like a good plan?

If I need venting I cant install a fan into the attic to release some heat.
