Bob, I do currently have misters set up, and they work all right keeping the temperature down. But I mostly collect Hippeastrum species and other bulbs that like to be mostly dry, and I have found that the extra water on them is not appreciated. Also I have hard water and so when the misters are on it leaves a white calcium residue on the leaves of the plants below the misters. Also undesirable. I am considering a “cooling wall” in my new greenhouse instead of misters. Chad in Elverta CA Sent from my iPhone Chad L.
