From the above plant and spectral data, the influence of each wavelength of light on plant photosynthesis is different, among the light required by plants for photosynthesis, 400 ~ 520nm (blue) light, and 610 ~ 720nm (red) contribute the most to photosynthesis, while 520 ~ 610nm (green) light, the efficacy rate of plants to exercise growth is very low. High Pressure Sodium Grow Light, Dual Head Grow Light Full , White Light Led Grow Light , Grow Light Spectrum ,315W Cmh Grow Light Fixture . 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,Romania, Philippines,Mozambique, Dubai.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.
