Ventilation is very important for grow rooms and greenhouses by helping to move humid air away from plants. The Destratification Ventilator extracts the humid air gently through vertical air movement at the ceiling. This prevents air from blowing directly on the plants causing the leaves to dry quickly, which can happen with wall mounted fans. With the design of the plastic shroud, a single fan can cover an area up to 2,000 square feet with a horizontal air throw of about 25 feet in all directions ensuring even air distribution throughout the grow room and the prevention of “hot spots”.
