I want to put the light portion up, so it won't be too close to the plants. The box is only 2' X 2' X 4'. I would like to put the fan to pull the hot air off, on the top of the box, and the intake near the bottom. I always thought that the fan pulling the hot air needed to be opposite the lamp end though, but both ends are open. Is there any reason that I CAN'T do this? (Intake on the completely open end, and pull off the hot air on the open end with the bulb?) :hippy:
