Maximize indoor grow light potential with HTG Supply Mylar liners. Mirror-like metalized Mylar surface reflects more light to plants, and more light = increased growth & higher yields! Line walls, ceilings, and even floors to ensure optimum lumen efficiency. Super-thick Mylar & black poly combo film is 100% lightproof and great for covering windows or creating blackout partitions or dividers between grow areas. Heavy-duty 6.7-mil thickness provides higher durability and smoother installed finish. Roll measures 4 ft. x 25 ft. Please Note: The metalized silver side does not produce a clear mirror image, and thus is not recommended for visual applications in which this quality is desired.
