The working principle of plant growth lamps is that the light emitted by LED components can provide the necessary illumination for plants, thereby promoting photosynthesis and creating an environment conducive to plant growth and development. Different wavelengths of light have varying effects on plant photosynthesis, with the required wavelengths for photosynthesis being around 400-700nm. Specifically, light with wavelengths between 400-500nm (blue) and 610-720nm (red) contributes the most to photosynthesis. Blue LED light primarily promotes stem and leaf growth in plants, while red LED light aids in flowering, fruiting, and extending the flowering period. Additionally, research has found that red-orange light significantly accelerates plant Развитие, улесняване на натрупването на сухо вещество и образуване на растителни органи .
