Mylar vs Matt White: The Truth About Grow Tent Reflectivity
About this episode
Dr. Russell Sharp explains how different grow tent materials — metallized PET/mylar, white films, panels and paints — affect reflectivity, light uniformity and photosynthetic efficiency, and why common assumptions (mirror-like is best) can be misleading.
He also shares a bold experiment: cladding a new grow room in dark maroon matte paint to optimize video contrast for microgreens, and teases future episodes on red:far‑red ratios and other lighting variables.
