ok, so i was sitting at the computer and looking at various solar type items.::stoned:

And i ran across a youtube video for a swamp cooler.
YouTube - 12v portable air conditioner camping tent

I swapped out the regular ice for dry ice. i made a smaller unit out of a 5 gallon bucket . i put water to about 2in deep and i dropped the dry ice in. fan blowing in the top with four 1in holes just under the lid on the side of bucket.

I used it in my closet grow for about the last 2 months. with great results.

I am not sure if anyone has mentioned this before. i just wanted to share with everyone.
