FAQ About Indoor Plant LED Growth Spectrums
What is the difference between PAR and PUR in the context of LED grow lights?
PAR (Photosynthetically Active Radiation) refers to the range of light wavelengths (400-700 nm) that plants use for photosynthesis. PUR (Photosynthetically Usable Radiation) is a subset of PAR that plants can directly utilize more efficiently.
While PAR covers the potential usable light, PUR focuses on the quality of the light specific to plant needs, which is essential for optimizing the LED spectrum's effectiveness for growth.
