 The Effection of LED Grow Light for Plant
 1, Different wavelength of light has different effection to plant.Plants growth needs photosynthesis. Research shows that 400-710nm wavelength of light plays an important role for plant , 455nm(Blue color light) and 660nm(Red color light) are playing the most important effection to the growth of plant .2, 455nm and 660nm wavelength of LED light are used to make LED grow light, when they match up with each other , the color of the light is purple red .3, About 455nm wavelength of light (Blue light) . It can promote the absorption of chlorophyll and carotenoid for plant , in this way, it has big effection for the growth of leaf and fruit .4, About 660nm wavelength of light (Red light) . It plays the most important role for the photosynthesis of plant , so it has big effection for plants root growth, promote and prolong the florescence, increase the products.5, The proportion of red and blue light . Different plants need different proportion of red and blue light, and different time of growing also need different light . Normally we use Red:Blue=6:17:1 , and Red:Blue=6:1 is suitable for nearly all kinds of plant.6, The distance of light and plant . Science research shows that 0.2-0.5 meter is a very good distance from light to plant .
