These custom made vent covers reduce the amount of light that penetrates through the fans on the backside of our grow boxes. They are perforated to allow optimal airflow, but still reduce the amount of light leaving through them. They are white on the exterior to match the grow box, and brown on the interior to absorb light.

They have little tabs to just slide in and mount on your grow box. No hardware is needed.

Come in a pack of 2  for the Roommate or 3  for the BloomBox or Producer.
