I have a 1000w hps light and was wondering if a air-cooled reflector with as many computer fans as needed would be sufficent enough to cool the box. I now it's a lot of light but when someone gives you a working 1000w you take it! I will be getting a smaller Hps/Mh light but not right now if I don't have to. thanks P.S The box will be 6ft high, 4ft wide and 2ft deep. Trying to make it look like a tall dresser.
Height is good, you will need only 2 120v cooling fans (the ones they use in CPU / Audio Equipment racks) they run down here in the caribbean 15 bucks, so has to be cheaper there.
Also how many plants do you think will fit in a 2x4 space using the sea of green technique? Is there a general space limit per plant?
