LED plant light knowledge:
1, different wavelengths of light for plant photosynthesis is different, plant photosynthesis requires light, wavelengths in the 400-700nm or so. 400-500nm (blue) light as well as 610-720nm (red) for the photosynthesis of the largest contribution.
2, blue (470nm) and red (630nm) LED, just to provide the light needed by plants, therefore, LED plant lights, the more ideal choice is to use these two color combinations. In the visual effect, the red and blue combination of plant lights appear pink.
3, blue light can promote the growth of green leaves; red light helps to blossom and prolong the flowering period.
4, LED plant lights of red and blue LED ratio is generally between 4:1 - 9:1 is appropriate, usually optional 4-7:1.
5, with plant lights to the plant to replenish the light, the general distance from the height of the leaves is about 0.5 meters, continuous irradiation of 12-16 hours a day can be a complete alternative to sunlight.
Colorful lights set in proportion can make strawberries and tomatoes become sweeter and more nutritious. Illuminating holly seedlings with lights mimics the photosynthesis of plants outdoors. Photosynthesis is the process by which green plants, through their chloroplasts, use light energy to convert carbon dioxide and water into organic matter that stores energy and releases oxygen. Sunlight is made up of different colors of light, and different colors of light can have different effects on plant growth.
LED light source, also known as semiconductor light source, the wavelength of this light source is narrower, can control the color of light. By irradiating plants individually with it, plant varieties can be improved.
Tested in the purple light under the holly seedlings, the highest growth, but the leaves are very small, the roots are shallow, a look of malnutrition. The seedlings under yellowish light are not only short, the leaves also look lifeless. The holly that grows under a mixture of red and blue light grows the best, not only is it strong, the root system is also very developed. The red and blue bulbs of this LED light source are configured in a 9:1 ratio.
The results proved that 9:1 red and blue light is most favorable to plant growth, after this light source irradiation, strawberry and tomato fruits are full, sugar and vitamin C content increased significantly, and there will be no hollow phenomenon. Continuous irradiation of 12-16 hours a day, growing in such a light source of strawberries, tomatoes, will be more delicious than ordinary greenhouse fruit.
LED plant grow lights can also be used to supplement the light source for plants in winter rainy weather.
