Right now ive got a 400W hood and ballast but I am moving to another room. It is about 36 square feet. If I stay with 400W HPS I will be less than 2000 lumens per square foot--not ok so I need some more juice. This is what I was thinking in addition to my 400W light hood: High Tech Garden Supply with High Tech Garden Supply With a 600W it would put me at 1K Watts and around, still small, a lux of 9000. minimal info is included about the light. I was hoping someone here has used it and can give me anything. It needs a fan i am assuming but it just doesn't say? Also can I run 400, 600, and 1000W with it? Lord I hate it when online sites dont provide necessary and flat out basic info, I dont get it do they just expect us to buy shit without a plan? Anyways what do you guys think about the equipment, my setup, my plan?
