As we all know, plant need light for growth but only the sun can help complete the photosynthesis of plants, but now LED grow lighting can simulate specific spectral composition of the sun, which is the studies already widely recognized.
The plant leaves chlorophyll absorbs most of three light with wavelength of about 400-700nm including the red, blue and violet light during photosynthesis, Unlike incandescent lamps the light-emitting principle of LED grow lighting is single LED chip, which can directly provide the plant with a spectrum during particular growth phase.
The blue light with 440-490nm wavelength can promote leaf growth; red light with 600-700nm wavelength help to extend the flowering and fruiting and flowering; violet light and ultraviolet with wavelengths between 300-440nm are the main light to promote the formation of plant pigments, and directly affect plants absorbing phosphorus and aluminum elements and vitamin D and the formation of the stratum corneum, as well as the accumulation of dry matter.
The plant factory is the factory floor superior to vegetable greenhouses , each plant has a different LED grow lighting, the plants cultivated with soilless can be moved to different plant for the promoting growth during the different periods, LED grow lighting for plant growth can not only be “fast forward”, but can slow down, the green and yellow light with 500-600nm wavelength suppress the activities of chloroplasts to decrease photosynthesis.
