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! Noah Led Grow Light, 680 Watt Cob Led Grow Light , Led Grow Light Driver , White Light Led Grow Light ,Led Full Spectrum Grow Light . 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,Benin, Burundi,Hyderabad, Armenia.These light sources are to make plants produce the best photosynthesis, plants to get the best growth state, experiments and practical applications have shown that in addition to giving plants in the lack of light time to get supplemental light, but also to promote the differentiation of multiple lateral branches and shoots during the growth process, accelerate the growth of roots and leaves, accelerate the synthesis of plant carbohydrates and vitamins, and shorten the growth cycle.
