LED Plant Growth Lights

1. Different wavelengths of light have different effects on plant photosynthesis. Plant photosynthesis requires light with wavelengths of 400-700 nm. The light of 430-440nm (blue) and 620-660nm (red) contribute most to photosynthesis.

2. Blue (420-430 nm) and red (630-660 nm) LEDs provide just the light that plants need, so the ideal choice is to use these two color combinations. On the visual effect, the red and blue combination of plant lamps is pink.

3. Blue light helps plant photosynthesis promote green leaf growth, protein synthesis, fruit formation; red light can promote plant rhizome growth, contribute to flowering and fruit prolongation, play a role in increasing yield!

4. The ratio of red to blue LED of LED plant lamps is generally between 3:1--9:1, and 6:1. is usually optional.

5. When the plant light is supplemented by the plant lamp, the height of the leaf is about 0.5-1 m, and the continuous exposure of 12-14 hours per day can completely replace the sunlight.

6, the effect is very significant, the growth rate is faster than the natural growth of plants almost 1.5-3 times.

7. Solve the problem of lack of sunshine in winter in greenhouse, promote chlorophyll, anthocyanin and carotene needed in plant photosynthesis, so that vegetables and fruits can be harvested 20% earlier, increase the yield of 3 to 5%, improve the sweetness of vegetables and fruits, and reduce pests and diseases.

8. LED light source is also called semiconductor light source. This kind of light source has narrow wavelength and can emit light of specific wavelength, so it can control the color of light.

9. LED plant growth lamp power is small, but high efficiency, plants only need red and blue light, so most of the traditional light energy is wasted, so the efficiency is extremely low. LED plant growth lamps emit specific red and blue light that plants need, so they are efficient, which is why the power of several watts of LED plant growth lamps is better than that of tens or even hundreds of watts. Another reason is the lack of blue light in the traditional sodium lamp spectrum, and the lack of red light in the mercury lamp and energy-saving lamp spectrum, so the complementary effect of the traditional lamp is much worse than the LED lamp, and compared with the traditional lamp to save more than 90% of electricity, running costs are greatly reduced.
