Is plant fill light effective? have This is for sure. For the growth of plants, it is well known that photosynthesis is necessary for plant growth, and plant lamps can precisely replace sunlight to carry out photosynthesis on plants. For plants that have not been illuminated for a long time, plant lamps can supplement the light source, promote the growth of plant seedlings or drive away mosquitoes, and reduce plant diseases.

Plant photosynthesis mainly involves absorbing red and blue light from the sun. To maximize the effectiveness of plant fill lights in providing light to plants, it is necessary to maximize the spectral adaptation of plants to their natural light needs. For example, LED plant fill lights are commonly used nowadays, with the most commonly used red and blue spectral fill lights having a spectral range similar to the absorption spectrum of sunlight by plant photosynthesis. So LED red and blue fill lights can effectively fill in the light for plants.

When using fill lights to provide light for plants, it is necessary to adjust the ratio of red and blue light according to the characteristics of the plant. For flowering and fruiting plants, the appropriate ratio of red and blue light is 7-12:1, while for leaf and rhizome plants, the best ratio of red and blue light is 1-5:1.
