Hydroponic Ventilation - Fan Speed Controllers
Fan speed controllers are made to change the speed of the fan in your hydroponic grow room or grow tent without harming it. Light dimmer switches from the hardware store can ruin your fan, so use a fan speed controller instead. Our fan speed controllers support 240V fans up to 2 Amps or 500 Watts. The Phresh Hyper Fan speed controllers are made specially to suit the Phresh Hyper Fan range of fans.
