What Does PAR Stand For?

PAR stands for Photosynthetically Active Radiation

Photosynthetically Active Radiation (PAR) refers to the portion of the light spectrum that photosynthetic organisms, such as plants and algae, utilize for the process of photosynthesis. Typically spanning wavelengths from approximately 400 to 700 nanometers, PAR is integral to energy conversion in plant life, influencing growth, development, and overall productivity in ecosystems. Understanding PAR is essential for fields such as agriculture, ecology, and environmental science, as it helps in assessing light availability for photosynthetic processes.
