Welp, decided there was no possible way to cool the temps down besides drilling another six inch hole in the ceiling. I am air cooling my hoods (three of them now that the 600 watter is in the line) through my Vortex fan into the attic. The air is being drawn from the heating vent which is typically pretty cool because it runs under the house.

My temps in the canopy are now 87 degrees, which is a moderate decrease but I haven't even turned the 600 watt lamp on yet, a bit concerned about where the temps will go from there. Doesn't 87 degrees sound pretty damn warm to you guys even with air-cooling the hoods? I suppose the seals on my lamps may not be great, but I have heard of growers having temps at 78-81 degrees with 2000 watts going, I am just trying to stay under 90! =(
