A Breathable Wall Light Trap at 12 x 12 in
Light and air want the same holes. Every intake and exhaust opening in a sealed room is a path for stray light, and covering it usually means choking the airflow. This panel is rigid blackout material built with fins, so air passes straight through while light does not. The opening it covers is 12 by 12 in, the smallest of seven factory sizes. It mounts flush to the wall with the frame it ships with. A simple cut-out in an exterior wall takes it, or a shared wall between two rooms. An adaptor plate lets you connect duct, fans or filters on the far side. The panel can also sit directly over an intake or exhaust fan. Fin depth on the custom units reaches 16 in. Factory widths run up to 96 in on unassembled kits.
Where Light Deprivation Rooms Use This Panel
Light deprivation is the obvious use, and it is what most of these go into. A blacked-out room still needs air exchange during the dark period, and an open vent undoes the whole schedule. The same trick builds inner rooms: one cooling system, two lighting programmes, no light bleeding between them. Veg on one side and flower on the other is the common layout. Installation is meant for interior walls. An exterior wall works, but the panel should stay out of direct sunlight, because intense sun finds its way through any fin geometry eventually. The honest limit is cost per opening at this size. A small panel costs more per square inch than the big ones, and the value climbs as the opening grows. Sizes above this one carry more area for the money.
