Reflective surfaces can be utilized indoors to increase light intensity and create more even light distribution. This is done by adding reflective materials such as white paint, aluminum foil, mylar, or other reflective films to walls, floors and ceilings of an indoor grow room. These surfaces will bounce light around the space more efficiently than non-reflective surfaces, thus increasing overall light levels in the room. Reflective surfaces can be used to help minimize hot spots that could occur when using high-intensity lighting fixtures. When using reflective materials indoors it is important to ensure they are properly sealed so they do not trap moisture which could lead to mold or mildew growth.
