I dont know if it matters, but I will be constructing the room of 2x4s and black and white poly. I saw a few threads on this and it seems like the best way for me to do it. I will be using an oscillating fan, as well as a stanley blower modified for exhaust, and a homemade carbon filter. 5 gallon buckets with the G.H. Dual diaphragm air pump, and Latewoods nutrient guide. Just need to know which light would be adequate. Thanks again...
