The effect of different wavelengths of light on plant photosynthesis is different, and the light required for plant photosynthesis has a wavelength of about 400-700nm. Light at 400-500nm (blue) and 610-720nm (red) contribute the most to photosynthesis. Blue light helps plant photosynthesis which can promote green leaf growth, protein synthesis, and fruit formation; Red light can promote the growth of plant roots, help flowering and fruiting and prolong the flowering period, and play a role in increasing yield! Phantom Grow Light, Led Grow Light Full Spectrum , New Board Led Grow Light , Led Light Grow Lights ,Rohs Led Grow Light 300 Watt . Water: Some plants are drought-tolerant, and some like sufficient water, which must be adjusted according to plant habits. The product will supply to all over the world, such as Europe, America, Australia,Amman, Rotterdam,Myanmar, Houston.In the past, the cost of LED lighting remained high, so plant factories mostly use fluorescent tubes or high-pressure sodium lamps, with the decline in LED prices and technological improvement, the application of LED in plant factories has seen a new wave of progress. At present, there are not many manufacturers engaged in LED grow lights in China, most of which are concentrated in Shenzhen.
