GREENHOUSE LIGHTING
refers to the wavelengths of light supplied (i.e. color of light), for example red light has wavelengths between about 630-700 nanometers, far red light is 705-740 nm, blue light is at 400-450 nm, and ultraviolet A is 315-400 nm. Plants can respond to different colors of light by changing their growth form (phytomorphology) – a high fraction
