A full spectrum LED grow light is designed to stimulate plant growth and development by emitting electromagnetic radiation with wavelengths across and beyond the photosynthetically active radiation (PAR) range (400-700 nm). Full spectrum horticulture lighting is meant to produce photons that provide photochemical energy for plant photosynthesis and trigger various plant physiological responses such as photomorphogenesis, photoperiodism, and phototropism. Electromagnetic radiation with a continuous spectrum covering all wavelengths from the UV to the far-red provides more balanced photosystem stimulation than narrow spectrum emissions from monochromatic red and blue emitters.
Full spectrum lights are typically used in indoor horticulture applications such as home grow systems and controlled environment agriculture (CEA) environments. Indoor cultivation allows growers to have more control over temperature, humidity, CO2 supplementation and other factors that influence plant growth, thereby maximizing plant productivity and consistency. In the absence of sunlight, the spectral composition of artificial light becomes a key component that goes into the design of horticulture lighting systems.
