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! 140 Watt Led Grow Light, 1000W Led Grow Light Full Spectrum , Led Grow Light Kits , Grow Light Glasses ,Kind Grow Light . 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,Ukraine, Peru,Egypt, Egypt.In fact, organic cultivation is not completely without fertilizer, but what can be used is organic fertilizer: farm fertilizer, mineral fertilizer, biological bacteria fertilizer, etc. after high-temperature fermentation and harmless treatment. Based on the limitations of this fertilization, the growth cycle of plants must be affected, and the current market demand is in short supply, so shortening the production cycle is one of the methods.
