Diamond Film is ideal for lining walls, ceilings, and floors of a growing area in order to optimize light distribution and quality. Diamond Film features a textured "diamond pressed" surface which not only reflects light but also disperses it evenly eliminating "hot spots" of light that could be harmful to the health of your plants. Sturdy 6 mil construction enables much greater durability over classic Mylar and will not crumple or scratch. Diamond Film is also waterproof and can also be used to help prevent algae and mold growth.
