How to choose led grow lights

　　Different wavelengths of light for plant photosynthesis is different, plant photosynthesis requires light, wavelength 400 ~ 720nm or so. 400 ~ 520nm (blue) light, and 610 ~ 720nm (red) for the greatest contribution to photosynthesis. 520 ~ 610nm (green) light is absorbed by the plant pigment ratio is very low.

　　According to the above principles, LED grow lights are basically made of a combination of red and blue, all blue, all red in three forms, in order to provide red and blue wavelengths of light, covering the wavelength range required for photosynthesis. The visual effect, a combination of red and blue light pink color plant.

　　White LED lights, the most common is to use a blue core, inspired yellow phosphor, thereby generating visual white composite effect. Energy distribution, in the area and 550nm blue 445nm yellow-green area there are two peaks. While the plant required 610 ~ 720nm red light, which is commonly short of. That's why the white LED light is very important for the plant growth.

　　LED Grow Light red and blue lights chromatography ratio is generally between 5:1 to 10:1 appropriate, usually optional 7 ~ 8:1 ratio. Of course, conditions can be adjusted according to plant growth cycle ratio of red and blue light is best.

　　LED Grow Lights Grow Lights for plants with a fill light, generally from the blade height of 0.5 to 1 m.
