How much light do various materials reflect? How good are they for indoor grows?
When growing indoors using grow lights, we want to maximize the emitted photons from the lamps. To prevent photons from getting wasted, we want to use as reflective materials as possible on the walls of our grow space. Grow tents are typically fitted with reflective mylar but how good is it really at reflecting light?
DIY inclined growers sometimes build their own grow rooms and dress the walls with reflective materials. We've seen Panda Film, mylar, white color, (mylar) emergency blankets, and aluminum foil is used. But which material reflects light most efficiently?
In this video we measure our LEDTonic Q2 LED grow light and the PPFD light footprint it emits when the walls of our grow closet are dressed in the above-mentioned materials. We compare the reflective properties to using no walls and also white walls.
The light intensity is measured with an Apogee MQ-500 quantum sensor.
