Hey, despite being a noob, first grow.. I'm using a 600w digital in a cabinet with 8 sq. ft and about 38 cubic ft of room in the grow chamber. I picked up a MH conversion bulb and it's working great for veg. What I've learned on a couple of warm days is cooling the box this summer is going to be a bitch. Currently, my lighting is in a sealed reflector with a dedicated cooling system, closed loop separate from the intake/exhaust system for the chamber. I have a Suncort 6" duct fan drawing air over the light and it seems to be working well, but I'm expecting to have to increase air flow during the warmer months.

In your original question you posted a substantial fan w/carbon filter.. Seems to me keeping your light colling system separate is the best approach.

Here's what I'm doing:

Well, this site seems to be overrun with underage smokers rather than of age growers, and there doesn't seem to be enough traffic in the grow forums, so I'm attempting at asking my questions seperatly. Will this exhaust a 1000watt HPS aircooled hood from a 4x4 hydrohut? Vortex 4 Fan Carbon Filter Combo - Vortex Power Fans Rating: 5
