Hey DGC I have been battling ridiculously high temps the last few weeks. Found some diy videos on YouTube and came up with my own diy swamp cooler. I had some leftover materials from my drain table so figured I could give it a shot. I used a fountain pump in a small cooler to pump water across the fan. On dry days this things pulls down 5-7 deg. from ambient. Not bad for under $50. Hopefully this inspires other DGC to take the idea and make a better one! Stay cool DGC! Growers love homieeees!
