This high CFM, highly efficent fan can be used within both traditional greenhouses or in a light dep greenhouse. When used in conjunction with a light deprivation system, it is recommended that this unit be paired with a Fullbloom 54″ Light Trap to block light from entering the grow environment while still allowing for ample airflow
