Abstract

A grow light fan is provided including a motorized housing, a fan assembly attached to the motorized housing and including a plurality of fan blades and a plurality of grow lights mounted on an underside of each fan blade. A controller is provided in the motorized housing and receives signals remotely, from a transmitter held by a user, to control the intensity of the grow lights and the speed and direction of the motor. A shroud and mounting bracket are also provided to secure and protect the grow light fan within a grow room.
