I am a local New Mexico native. Putting together a aqua ponics system. I would like to grow trout. I need to keep my water under 70 degrees. Any suggestions on how to do this on a budget?
In NM, you might be better off figuring out how to keep it in some kid of sealed insulated shelter with an AC unit. Or build a water coil inside a second had refrigerator and pump your water through that.
