Which heroes know method of making LED light plant?
Plants need light for photosynthesis, at wavelengths of 400 - 720nm. 440 - 480nm (blue) light and 640 - 680nm (red) contribute most to photosynthesis. 520 - 610nm (green) light, which is absorbed by plant pigments, is very low
LED light plant is a plant growth lamp, must need sun light in accordance with the law of plant growth, and plant lights is the use of the principle of sun light, a lamp lights instead of the sun to provide a better environment for the growth and development of plants.
According to the above principle, the plants are basically made of red and blue light blue and red combination, all three forms, covering the wavelength range for photosynthesis. In the visual effect, the combination of red and blue lights appear pink. Red light promotes plant germination and flowering, and blue light promotes plant growth, allowing you to select a more appropriate wavelength and color ratio to promote plant growth.LED plant lamp red, blue lamp chromatography ratio is generally between 5:1 - 10:1 is appropriate, usually optional 7 - 8:1 ratio. Of course, conditional, according to plant growth cycle adjustment, red and blue light ratio is best.
