LED lights are widely used in the plant: greenhouse, greenhouse farming, flower cultivation, indoor gardens, water soluble breeding, pipeline cultivation, farm, plants, plant spray, tissue culture. Suitable for any stage of plant growth, and the aqueous solution culture or soil cultivation valid.LED application principle: completely simulated sunlight for photosynthesis in plants and choose the most favorable for plant growth spectrum mix, targeted the plants fill light. Plant photosynthesis effective wavelength between 400 ~ 700nm, where blue 425 ~ 460nm and 620 ~ 660nm red light for photosynthesis, the maximum contribution rate, and 520 ~ 600nm (green) light is hardly absorbed by plants, but different environment is essential spectrum.Thus, not all plants are totally dependent on (red / blue) for photosynthesis. Plant pigments can absorb light energy to produce a series of biological reactions spores, different dye absorption wavelengths of the different, each with a different role. There are a lot of pigment in plants, but there are two pigments that phytochrome and Cryptochrome wake plant plays a vital role in regulating the light right. Phytochrome has two tautomeric isomers spore - red phytochrome (Pr) and far-red phytochrome (Pfr). Pr absorption wavelength of about 660nm red light, Pfr absorption wavelength of about 730nm far-red light. Phytochrome regulate a variety of different plant responses to light, including light cycle, seed germination, leaf, hypocotyl elongation and de-yellowing. Cryptochrome absorb the blue and UV range of the light, and the light pigment and other plant related to the development.
