This waterproof poly film is black on the outside and white on the inside. The black backing and white surface work together to reflect 90% of the light striking it and send light back to the growing area. The waterproof, light-proof film also helps prevent algae and mold growth on walls. Double it up by putting the black surfaces together to economically and effectively partition off indoor gardens. Availability: Usually ships in 2-3 business days. B&W; Poly 10X100 ft BWP100
