I wonder, can reflective surfaces in the marijuana grow room augment plant growth?
Any light that doesn’t make it to your marijuana garden is wasted. There are many different reflectors and many different patterns that they create. Obviously, areas directly under the light get the highest levels of light intensity. To the sides, the light is less intense, and some of the light is sent to sections of the room that are outside the garden. To really optimize plant growth, it’s important to reflect that light back into the garden so the marijuana plants can use it. Mylar reflects over 90% of the light, while mirrors generally reflect about 70% or less. Aluminum foil reflects around 75%; flat white paint reflects about 85%; and semi-gloss white paint reflects about 80%. Clean Styrofoam reflects almost 100% of the light.
