Keeping Greenhouse Cool

[WolfinKW]

The only thing I'm wondering is why buy one when all you really need that you can't do it yourself would be the specific pads aspen shavings in a form of somekind is what the one site I saw recomended. The rest just sounded like a blower forcing hot dry air through them and a pump to pump water to the shavings. You could make it as big or little as you want and if you think about it... it may be possible to use the same motor that drives the fan to move the water in some way.

We made our swamp cooler ourselves out of roof gutter and a cattle watering tank. The pads fit perfectly in the gutter ledge, and it was just a matter of drilling holes in the PVC pipe above them to make a spray bar. Gutter above them and below keep the water contained. We had to buy the electric louvers of course, but the whole system cost less than 1/4 of what a turnkey papckage would have run.
