Take control of your garden’s climate and atmospheric environment with our complete line of climate controllers. Inline duct fans are great for ventilation for heat and humidity removal. They can also be attached to carbon filters for odor and dust control. Clip-on fans and oscillating fans are used for air movement to prevent common mold and mildew problems, to increase the strength of stems and stalks, and to dissipate the heat of HID bulbs. Greenhouse Controllers (thermostats, humidistats, etc.) are used for partial to complete garden automation, making it simple to coordinate fans, lighting, hydroponic pumps, CO2 injection systems, air-conditioners and heaters.
