Back in early July I was starting to lose chile plants in my Outdoor Hydroponic system. The leaves were curling downward and getting a plastic like look to them and then yellowed. My plants were also not growing. I frantically started replacing them. I had grown many plants to sell so this helped me. Then I figured out the problem. My water temps in late afternoon were getting a little over 90 degrees. So fist I put up 50% grade shadecloth inside the greenhouse to block more of the sun's rays and heat. It helped a little. Then I blocked the sun from hitting my water pipes in the back of my greenhouse and put a 70% shadecloth on the sidewall to keep sun from directly heating tubes that faced the northwest. This also helped very little. I also put foam insulation around every pipe that came up out of the ground and every feed line. All of these measures were not enough but they did keep my supply water below 90 degrees for a longer period of time. As we started to face days of 100 degree temperatures I finally put in drip irrigation line above my system with fogger mister heads. Finally I had sucess! By running the foggers for 2 hours a day my air temps dropped almost 15 degrees and my water temps were now below 80 degrees on days of 100 degrees outside. The following pictures show my plants responding and getting green again.
