Green Air THC-2 Total Humidity Controller
The THC-2 controls humidity automatically and switches between humidify and dehumidify modes. It powers your equipment whenever relative humidity varies from the adjustable set point. In dehumidify mode, high humidity runs your fans or dehumidifier until RH drops about 5%. Then it holds off until humidity climbs 5% again.
Holding Grow Room Humidity in Either Direction
Run it in dehumidify mode to pull damp air in late flower, or in humidify mode to add moisture during propagation. Wire your humidifier or dehumidifier through the controller and set the dial. The 5% span keeps the equipment from short-cycling on small swings. Place it where it reads average room air, not next to the mister or the intake.
