Can ordinary LED lights be used to supplement light for plants?

NO! Ordinary LED lights are only suitable for illumination purposes, and producing plant lights has a very poor result. The additional lighting used for plants has to be specifically calibrated for its spectrum. Red and blue light are essential for plant growth and development, and the proportions of red and blue light needed by various species vary.


The LED plant growth lamp's illumination mechanism

The LED plant growth lamp uses the semiconductor illumination concept. It is a plant growth auxiliary light that uses high-precision technology to produce flowers, vegetables, fruits, and other types of plants. Generally speaking, indoor plants and flowers go worse with time. The major justification for this is that, in the absence of light irradiation, the irradiation of LED lights appropriate for the spectrum needed by plants may not only boost their development but also lengthen the blooming time and enhance the quality of flowers. Further utilising this high-efficiency light source system in agricultural production, such as greenhouses and greenhouses, can address the drawbacks of the lack of sunlight that results in the loss of flavour in greenhouse vegetables like tomatoes and cucumbers, as well as the ability to hasten the growth of solanaceous vegetables in winter greenhouses. To fulfil the goal of off-season cultivation, it will be available on the market around the Spring Festival.


Various plants need various colours of light.
The wavelength of the light that plants need for photosynthesis ranges from 400 to 720 nm. The most beneficial wavelengths for photosynthesis are 400–520 nm (blue) and 610–720 nm (red). Plant pigments absorb 520–610 nm (green) light at a very slow pace. In order to give light of two wavelengths of red and blue, encompassing the wavelength range needed for photosynthesis, plant lights are mainly constructed in three forms: a red and blue mix, all blue, and all red. The colour pink is created by the pairing of red and blue plant lights. There is a full-spectrum fill light that is white and similar to natural light in addition to the red and blue light plant fill light. It works well as fill light for indoor gardening and has a fill light impact on fruits, flowers, and vegetables.

Normal LED lights have more green and blue light and less red light. Plants' need for light cannot be fully met by standard LED lighting.
