Light traps are the best way to ensure total blackout in a light deprivation greenhouse setup. The plastic structure in a metal housing is fastened over the ventilation opening to prevent light from leaking into the inside of the greenhouse. Used properly, they eliminate the need to choose between complete darkness and proper ventilation within the greenhouse.
Our 54” light traps are well-built to provide the best blackout possible. All light traps are shipped unassembled to help with shipping costs, assembly instructions included.
