Hydroponics Mylar Standard 2 Mil Reflective Material 50" x 100'

This is for one roll of 50" x 100' 2 Mill Standard Reflective Mylar Film (1mill is the cheap stuff that doesnt last) Mylar is a plastic film kind of like tin foil but it will not rip or cause "hot spots" on your plants. Using Mylar will increase the light to plant ratio and overall lumen count. Mylar also helps even out plant growth by reflecting the light around the outside of your plants back towards the plants. In-other-words the plants that are not directly under the light and are more on the outside of your area will benefit the most from the Mylar. Indoor gardeners use Mylar in an indoor garden to save precious light: 98% of the light striking it is reflected to plants where it belongs. Mylar is a metallic film that can be taped or tacked directly to a flat surface or wall.
