Led grow light is used for plants, such as vegetables, fruits, medical plants and so on, to help plants grow better and fast, short the growing cycle and increase the weight.
For led grow light, the spectrum is the most important thing of it. In general, red and blue light have the greatest impact on photosynthesis, the wavelength of blue is 400-520nm, the wavelength of red 610-720nm, chlorophyll A mainly absorbs 430nm and 660nm, chlorophyll B mainly absorbs 460nm and 630nm, so enough blue and red will be helpful for plant to grow up. At the same time, different stages of plant growth require different amounts of light, during the seedling stage, plants need more blue light to help germinate, at the growing season, plants need plenty of red and blue light to help their stems and leaves grow, at the fruiting period, plants need more red light to produce fruit. If you think this a bit of a hassle, having plenty of blue and red light is one of the most convenient options.
In addition to the spectrum, high CRI white full spectrum can also help your plants grow, we’re using CRI>90 white full spectrum for some seedling stage plant if you don’t need so high PPF at the first stage, it’s a very cost-effective solution for some vegetable seedlings.
