1. Different wavelengths of light on plant photosynthesis influence is different, plant photosynthesis to light wavelength at about 400~720nm. 400~500nm light (blue) and 610-720 nm (red) for the largest contribution to the photosynthesis.
2. Blue (450nm) and red (630nm) of the LED, just can provide plants need light, and therefore, the LED grow light, ideal choice is the use of these two kinds of color combination. On the visual effect, combination of red and blue lights pink plants.
3. Blue light promotes green growth, Red light helps to blossom and prolong flowering
4. To fill light to the plants, generally the distance blade height is 0.5 meters, lighting 12~16 hours a day can completely replace the sunshine.
