does/did anyone have high temps in there dwc? did you fix it? yes yes diy water cooler, but open to other suggestions. besides water bottles, open to ideas, cheap chillers maybe?
People don't realize how bad a constant supply of warm/hot water to the plant. It becomes to easy for roots to pick up various diseases and problems. Not sure how much a window a/c will help with the water temp. Buy a decent water cooler and be done with it. It's more important to control (lower) root/water temps then room temps......
look into silica! also, always remember that a space between your canopy and bucket is very important. proper air circulation and temperature control will help it from getting too hot.
