MH reverse cycle

[skylord]

I have used the frozen water/pop bottles to help a little. The best thing I found was a couple of clip on fans from the supper store for $12 each and ran those over my sump. Ran one on the actinic light cycle and the other on the halide cycle so both were running when the halides were on.

I use a fan too on my 29g bio cube, which had its top removed and is now lit by 175w MH. Temperature is under control but evaporation is soemthing to deal with
