Cooling in small spaces

[daihashi]

update.

After about an Hour my temps rose up to 82 degrees and have stayed there steadily.

This is with 2 box fans.

The intake is pushing through a fiberglass air cleaner (the kind you use for your house a/c.)

The exhaust is pushing through some wire, A/C filter and 2 inches of activated carbon (10lbs total) across a 20x20 space.

I can't say as of yet if the carbon filter is working, but I think it is. I'm having a friend come by later and test it with his nose.

I can definitely say this. When I open the cab door the smell hits me hard. When the door is closed I don't smell anything. Previously I had a hard time smelling the plants when I opened the door because I Was used to smelling them slightly all day long. So it looks like something is working. We'll see though.

on a side note.. I'm pissed. When I went to go check my temps I spilled like 3/4 of a container of Sweet. UGH!!!!! I haven't even used it yet, I'm not sure how the cap was off/loose.

daihashi Reviewed by daihashi on 03-05-2008. Cooling in small spaces A wooden box with dimensions 36"x20"x60" (25 cubic feet) sits inside a closed space measuring 37"x61"x93" (121 cubic feet). The closed space is used for storage and so actually has less room than that available. Is it possible to use a 400 watt HPS light with hood inside the wooden box and still maintain optimal temperatures? Preliminary tests suggest that temperatures easily exceed 100°F within the box, using 2-3 80mm fans each on intakes and outtakes. The light itself generates most of Rating: 5

sure are expensive though. too much in my opinion for a personal grow. you can air cool your lights for much cheaper.

Take a hundred or so bucks and invest in inline fan 365 cfm should be enough.
Install all your fans that you have now at the top to exhaust the hot air and create a passive intake.
Last but not least option, install an A/C 75 bucks...
