Plants need sunlight to thrive. The effect of light on plant growth is to promote plant chlorophyll to absorb nutrients such as carbon dioxide and water to synthesize carbohydrates. However, modern science can make plants grow better in places without the sun. People have mastered the internal principle of plants' need for the sun, that is, the photosynthesis of leaves. During the photosynthesis of leaves, the excitation of external photons is needed to complete the entire photosynthesis process. The sun's rays are the energy-supplying process of photon excitation. Artificially created light sources can also allow plants to complete the photosynthesis process. Modern horticulture or plant factories combine supplementary light technology or complete artificial light technology. Scientists have found that the blue and red light regions are very close to the efficiency curve of plant photosynthesis and are the best light sources for plant growth.
LED plant light knowledge:
1. Different wavelengths of light have different effects on plant photosynthesis. 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.
2. Blue (470nm) and red (630nm) LEDs can just provide the light required by plants, therefore, LED plant lights, the ideal choice is to use these two color combinations. In terms of visual effects, the red and blue combination of plant lights is pink.
3. Blue light can promote the growth of green leaves; red light is helpful for flowering and prolonging the flowering period.
4. The ratio of red and blue LEDs of LED plant lights is generally between 4:1--9:1, usually 4-7:1.
5. When using a plant lamp to fill the plant with light, the height from the leaves is generally about 0.5 meters, and the continuous irradiation for 12-16 hours a day can completely replace the sunlight.

Using LED semiconductor bulbs to configure the most suitable light source for plant growth
Proportional colored lights make strawberries and tomatoes sweeter and more nutritious. Lighting holly seedlings mimics the photosynthesis of plants outdoors. Photosynthesis refers to the process by which green plants use light energy through chloroplasts to convert carbon dioxide and water into organic matter that stores energy and release 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, has a relatively narrow wavelength and can control the color of light. By irradiating plants individually with it, plant varieties can be improved.
The holly seedlings tested under the purple light grew the tallest, but the leaves were small and the roots were shallow, and they looked malnourished. The seedlings under the yellowish light are not only dwarfed, but the leaves also look lifeless. The holly grown under the mixed light of red and blue grow best, not only strong, but also very developed root system. The red and blue bulbs of this LED light source are configured in a 9:1 ratio.
The results show that 9:1 red and blue light is the most beneficial to plant growth. After this light source, the strawberry and tomato fruits are full, the content of sugar and vitamin C is significantly increased, and there is no hollow phenomenon. Continuous irradiation for 12-16 hours a day, strawberries and tomatoes grown under such a light source will taste better than ordinary greenhouse fruits.
LED grow lights can also be used to supplement light sources for plants in rainy weather in winter

The LED plant growth light adopts imported chips, with high brightness and low light decay, low energy consumption and high efficiency, and the effect of promoting plant growth is obvious. It has the characteristics of extremely low energy consumption and long life. Used for lighting in plant cultivation places, it can replace sunlight to supplement light for indoor flowers, greenhouse vegetables, garden nurseries, etc. to promote, adjust flowering, and maintain survival. The fill light effect is absolutely superior to traditional plant fill lights such as high-pressure sodium lamps, low-pressure sodium lamps, metal halide lamps, Philips plant fill lights, and rare earth plant fill lights.
