Good thread.

For $17 I got one of these bad boys. There is actually a six inch model. This one is 4". Intakes on either end. First think I did was cellophaned off back end and yessiree she pulled even harder on the one end. Nice and efficient and I must say pretty quiet. Easy to fit up to 4" ductwork. Get the flex stuff at HD. Expands to 8'. Awsome. Larger model possibly indespensable to you big bulb boys at this price.
Rezinator Reviewed by Rezinator on . closet ventilation problem!! I'm tryin to put together my first grow room. ive got decent closet space. its 5ft x 8ft x 2ft deep with sliding doors. But I need a lil help w/ an acceptable way to ventilate it. I can't damage walls, so couldn't run any kinda duct work. could fans be used to cirulate air, or must there be a way to some way for air to get in and out of the closet. Also, I wanna partition the closet in a flowering room and a cloning/veg. room. Thinkin about 400w HPS for the flowering section and 150w HPS Rating: 5
