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! =(
razzapiggy Reviewed by razzapiggy on . Ventilation Problems So I am a few cycles through, having a problem for the first time here. I live in Nothern California and have not have temp problems since I started growing. That was until four days ago. I had the babies comfortable under 1000 watt lamp, but I transplanted and had to turn on the second 1000 watt lamp and my temps in the canopy are hitting as high as 92 degrees. This is a huge suprise to me because the house is very chilly usually, heck I had to run a heater over the winter to keep my temps Rating: 5
