hi all. i painted my grow room's walls with a chrome color. the spray is used usually for car bumper, and the side i painted is more reflective than foil, and bright white wall or material. my only concern is if it sucks heat. any suggestion please?
Flat, white paint will reflect around 90 percent of light. Any aluminum color will reflect less. Shiny Mylar will reflect a little more, but only if it is perfectly flat, with no wrinkles or waves.
