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! 250W Grow Light, Grow Light 1200W , Lights Grow Light , Grow Light Cmh ,Plant Light Led Grow Panel Lamp .
