Cache FFA installs new greenhouse technology Cache FFA gets new technology By Cheyenne Cole | March 8, 2021 at 6:34 PM CST - Updated March 8 at 6:34 PM CACHE, Okla. (TNN) - Cache Public Schools FFA students and agriculture teachers are excited about a new water wall cooling system installed in their greenhouse. When air from the outside comes through the cooling pads soaked in water, it provides a more humid environment for plants and vegetables to grow. The FFA adviser Kelly Jenkins said it’s perfect for the Oklahoma weather. “Without the cooling system, we’re basically dealing with the hot, dry Oklahoma air,” Jenkins said. “We do have fans that come through, but you’re just basically bringing in dry air in from outside, so having the cooling system’s providing the water and humidity level in the greenhouse is actually much more conducive to grow plants much quicker and more efficiently.”
