The Science

Growers can control the humidity levels in the grow room or a commercial space with the Quest 155 Dehumidifier. The premium product comprises an onboard humidistat, Plug & Play installation, and overhead installation. The humidistat allows growers to determine optimum conditions such as dry, normal, and humid. When the humidity in the grow room exceeds the pre-set levels, the unit will start running until the humidity level drops between at least 4% and 6%.
