Hi all. I'm starting my first grow in my closet on June 1st. I'm in need of some advice regarding the ventilation. First, here is what I am working with: Grow space is 8' high X 2.5' wide X 1.75' deep, about 4.5 square feet in area and 35 cubic feet in volume. Sunleaves ArcticSun reflector, 6" tubing vents on either side Sunleaves WindTunnel 6 for light ventilation (6" duct openings, 70 watts, 409 cfm) I have not decided on either 250, 400 or 600 watt lights yet, but it will be one of the three. To keep the light from building heat, I planned on having the fan intake air from an adjacent air conditioned closet, blow it over the light and vented through the ceiling of the grow space into the attic. For odor control, I originally planned on having another WindTunnel fan with carbon filter on the intake, vented through the ceiling of the grow space into the attic also. Here is where I need some advice. Can I put the carbon filter on one end of the reflector and have the one fan intake through the filter, over the light and then vent through the ceiling into the attic? I have read that you should always blow air over your light, not suck it over the light. I guess the heat interferes with the fan's parts. That is the only reason I was going with the two fan setup in the first place. However, if it isn't that big of a deal, I'd rather go with the one fan setup because of ease of install. Nothing in the WindTunnel fan documentation says anything about it either way. I'm just looking for the best setup to control the heat from the light and smell. Those are of paramount importance for me (and most others, I would assume). I don't have a problem using the two fan system if that is clearly the better way to go. Thanks in advance GC!!
