Temperature Control!

[k1ucHt]

Hey everyone I'm currently running a closet grow in a 4ft high, 2ft wide, 2ft deep space. The temperature is currently at 91 and I am looking to take it down at least 6 degrees and I would like some suggestions on how to go about doing so, I cannot run a window unit and access to outside air is virtually impossible.

job1.5, what did you use to make the tube?

k1ucht, what is the temp of the are being drawn into the closet by the intake fan?

where do you have the thermometer? if it's in the direct light you will get a false temp. reading!

What I did to control temp via venting was put a 4" axial DC fan (from bghydro) near the top of my cabinet, and have two 1.5" PCV pipe intakes near the bottom. But the pvc pipes are connected to a single long pipe that sucks cool air from the floor, several feet away from the cabinet so as not to suck up air that was vented out. Each PVC pipe intake has a little DC axial fan on it that I got from some litter box air fresheners at Target.The temperature goes no higher than 85 now.

i am gonna upgrade my current non-aircooled 400hps hood to a cooltube, thanks for the info, i didn't know what to use for the tube and the cheapest i could find a cooltube online was like $150 for just the tube, mogul socket, and cord.

THANKS, I'LL DO THAT. i got a glass storm lamp cover. you know the thing that blocks the wind from the wick. anyway, it was $1.74 at walmart but the 400hps bulb is to fat to fit inside!

The current temperature under just the CFL lighting is between 80 - 85 degrees. Here is a picture of the thermometer placement, is that ok? I suppose it is in direct lighting but to me thats the only way it could be done.
