The Greenhouse Blackout Screens are engineered to provide the absolute light exclusion required for the precision cultivation of short-day and light-sensitive crops as well as meeting local bylaw regulations. These screen systems achieve 99.9% light deprivation. By utilizing high-density, UV-stabilized synthetic fabrics with integrated aluminum layers, our blackout screens serve a dual purpose, they provide total darkness while acting as a powerful thermal barrier, reflecting radiant heat back into the crop to reduce energy consumption.
