What are the effects of LED lights on plants

1. Different wavelengths of light have different effects on plant photosynthesis. The wavelength of light required for plant photosynthesis is around 400-700 nm. led mesh screen，Light at 400-500nm (blue) and 610-720nm (red) contributes the most to photosynthesis.

2. Blue (470nm) and red (630nm) LEDs can only provide the light that plants need. Therefore, the ideal choice for LED grow lights is to use these two color combinations. Visually, the red and blue combination of the plant light is pink.

3. Blue light can promote the growth of green leaves; red light can help flowering and prolong the flowering period. The ratio of red and blue LEDs of LED plant lights is generally between 4:1--9:1, generally 4-7:1

4. When using a plant lamp to fill the plant with light, the height from the leaves is generally about 0.5 meters, and continuous irradiation for 12-16 hours a day can completely replace sunlight.
