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! 3M Grow Light Black, 1000W Grow Light Kit , 2700K Grow Light , White Led Grow Light ,Led Grow Light Indoor Plants . Observe which plants are completely in the sun? Which ones are in the shade? When do the plants next to the wall get the sun? From this, you can further find out the growth of the same plant in different places, so that you will have a better understanding of the growing conditions required by the plant. The product will supply to all over the world, such as Europe, America, Australia,Melbourne, Germany,Tunisia, Morocco.With the extensive development of the LED industry, LED companies are constantly looking for new development outlets, LED grow lights are undoubtedly to give LED companies a chance to be reborn, but despite the prospect of plant grow lights, the development of plant factories still faces some bottlenecks. For example, the early investment is too large, and an artificial light plant factory with a daily output of 1,000 lettuce plants generally requires a relatively high initial investment. Even if the government subsidizes 50%, it usually takes 5-7 years to become profitable. In addition, the planting technology in the era of factory agriculture has yet to mature, and the related quality control, logistics and sales models are also being explored.
