Mega room.. think before you act and you wont regret it.
I would first try and grow in Vanessas tight space, then move your way up to the closet. Is there an atic above the closet? there are certainly ways to make that a hard hitting machine.
Mylar the everything, weather strip the door (all but the bottom) allowing the fan to suck air from the coldest part of the room and forceing it out through the quiet fan 5 CF nesting in the atic. You could do 2 400w lights of each flavor, on one vent out doing a split level closet to properly stage. This makes a diffrence. Oh and bring your power in through the atic as well.. few closets have outlets until modified to do so.
Look forward to the pics.. oh and some of the closet also
