I plan on using my 5x5x8 closet with a corner sectioned off for vegging. Im making the flowering part of the room completely light proof too. I do have a floor drain just around the corner and i plan on using distilled water only...i have alot of crap in my tap water in my area, so i figured it would be the best to use distilled...

I also have another question, will the temps from the light keep it warmer then it should be (around 85 degrees F) or just right, or lower then what it should be? The closet is insulated if that helps. I plan on running an intake and exhaust duct with a squirrel cage fan and a small carbon filter. Also ill put a small oscilating fan in both sections of the room.
