swamp cooler

[Carlos]

Hi Ron, tanks for your answer, i am getting more and more interested with all i read in this bulletin
board it's a great idea to help us go on in our hydroponics proyect; i have read in one of your answer
about a swamp cooler, can you give me an idea of how to build one, is there a blueprint or some
picture to guide me. here in Venezuela is as hot as Florida and for tomatoes and lettuce is a very
hard tempeture.
