Mylar / White Poly 4 mil - 25ft

For maximizing reflectivity in your grow area, Poly-backed Mylar is a low-cost tool to boost productivity in your garden. In a small space like a spare room, closet, or custom box, light energy is lost on walls and other non-reflective surfaces.  Poly-backed Mylar solves this issue by giving growers a 95% reflective surface that is easy to use, easy to clean, and tough enough to last years in an indoor garden. 95%+ Reflective Mirror Like Finish 4mil Poly Backing for reinforced strength when hanging on walls. Recovers light that is otherwise lost to absorption by non-reflective surfaces. By properly lining a garden with this Mylar, you could increase the amount of light your plants receive by up to 30%!
