3 Common Mistakes of LED Plant Growth Lamp Lighting

Regardless of the energy-saving effect, the selectivity of light and the coordination of light, semiconductor lighting has shown great advantages. However, from the rapid development of the past two years, we have also seen a lot of misunderstandings in the design and application of light. LED tube lights for growing plants mainly have the following aspects.


1. Wavelength application of led grow lights


Plant grow lights can be used in plant cultivation as long as the red and blue chips of a certain wavelength are combined in a certain ratio, such as the ratio of red to blue of 4:1, 6:1, 9:1 and so on.


2.The light source made by LED tube lights for growing plants is better


As long as a light is white, it can replace sunlight, such as the widely used three-primary white light tube, etc.. The use of these spectrums has a certain effect on the growth of plants, but the effect is not as good as the light source made by LED tube lights for growing plants.


3. Parameter design of LED tube lights for growing plants


As long as PPFD (Photosynthetic Photon Flux Density), an important parameter of illumination, reaches a certain index, for example, PPFD is greater than 200μmol·m-2·s-1, but when using this index, be sure to pay attention to whether it is a shade plant or a sun plant. And you need to inquire or find the light compensation full point of these plants, which is also called light compensation point. In actual applications, seedlings are often burned or withered. Therefore, the parameter design of the LED tube lights for growing plants lighting must be designed according to the plant species, growth environment and conditions.


For fluorescent tubes with three primary colors commonly used in previous years, although white light is synthesized, the red, green, and blue spectra are separated, the width of the spectrum is very narrow, and the continuous part of the spectrum is relatively weak. At the same time, the power is still relatively large compared to the LED tube lights for growing plants, 1.5 to 3 times the energy consumption. Therefore, the use effect is not as good as LED tube lights for growing plants.
