Before delving in o your question, let's discuss photosynthesis. Photosynthesis, also known as light energy synthesis, occurs in green plants, certain bacteria, and organisms with chloroplasts. Through the photochemical and carbon reactions (formerly known as dark reactions), photosynthetic pigments utilize visible light to convert carbon dioxide (or hydrogen sulfide) and water in o organic matter, while releasing oxygen (or hydrogen). This biochemical process involves the conversion of light energy in o chemical energy within organic compounds.

The general equation for photosynthesis is 12H2O + 6CO2 + light → (chemical reaction with chlorophyll) C6H12O6 (glucose) + 6O2 + 6H2O. Photosynthesis consists of two main phases the light reaction and the carbon reaction. For the purposes of our discussion, let's focus on the light reaction. The light reaction formula can be represented as follows 2H2O → 4[H]+O2↑ (catalyzed by light and pigments in the chloroplasts) ADP + Pi → ATP (catalyzed by enzymes). The primary pigments involved in the chloroplasts are chlorophyll a and chlorophyll b.


Now, let's explore which light wavelengths chlorophyll mainly utilizes in photosynthesis. If I recall correctly, Leaf A predominantly absorbs red light, Leaf B primarily absorbs blue-violet light, and green light is the least utilized. However, this doesn't imply that green light is completely unused. Now that we've covered these basics, let's move on to comparing different light sources and sunlight using various spectral comparison charts.

By examining these charts, it becomes evident that LED lamps, with their wavelengths of red-orange and blue-violet light, are better suited for providing illumination to small potted plants, emulating sunlight. Additionally, plants thrive under continuous light as photosynthesis is a process that doesn't tire out the plants, and prolonged exposure to light promotes their rapid growth.


The spectrum of LED grow lights can be more potent compared to other lighting options, thus enhancing plant photosynthesis and increasing yields. For more professional advice, please feel free to reach out to Lippen Technology directly.
