Red and blue light functions: Blue light: prevents leggy growth (plant branches grow too long, not thick, etc.) Red light: helps plants grow, bloom, and bear fruit Red and blue light: normal supplementary light for plants growth, flowering and prevention of leggy growth It is well known that sunlight is composed of many different wavelengths of light waves, and only about 5% of the solar radiation spectrum affects photosynthesis. Among them, blue light with a wavelength of 400 ~ 520nm and red light with a wavelength of 610 ~ 7200nm contribute the most to photosynthesis.   Experiments show that red light in photosynthesis is beneficial to the synthesis of sugars and carbohydrates, accelerates the development of plant nodes, converts excess energy into heat energy, and evaporates water. Blue light is beneficial to the synthesis of proteins, has a greater impact on plant growth and the formation of young shoots, can inhibit the elongation of plants and make them short and strong, and can also control cell differentiation, which is beneficial to the synthesis of anthocyanins and vitamins. Therefore, blue light and red light are called light fertilizers, which are a new type of environmentally friendly "physical fertilizers" after "chemical fertilizers". Therefore, the best spectrum for artificially simulating plant effects has the functions of fertilizer and drug effects, which gives new meaning to the development of efficient ecological agriculture. Artificial Plant lighting source can avoid the waste of light and electricity, and can quickly improve the growth efficiency of plants Basic parameters of red and blue light plant growth box: ① Layer height: double layer is 470 610mm, single layer is 960 1240mm (the height of the storage rack is adjustable). ② Single wavelength: red light 650nm, blue light 450nm. ③ Red and blue light ratio adjustment range: 1:9 9:1 continuously adjustable. Stepless dimming ④ Illuminance adjustment range: 0 5000LX (100mm below the illumination board).
