What is PAR?

PAR (Photosynthetically Active Radiation) is a region of the light spectrum (400 to 700 nm) that plants utilize for the process of photosynthesis. PAR is not a measurement or metric but defines the range of light needed to support photosynthesis.

What is PPF

PPF (Photosynthetic Photon Flux) is a measure of the total amount of light within PAR that a light source emits each second. The unit used to express PPF is micromoles of photons per second (µmol/s).

What is PPE?

PPE (Photosynthetic Photon Efficacy) is the PAR photon output of a light source (measured in micromoles per second or µmol/s) divided by the input power (Watt) to produce that light, the measurement is µmol/J. PPE does not include the photons outside the PAR range. 

What is PPFD?

PPFD (Photosynthetic Photon Flux Density) measures the amount of light within PAR that actually falls on a given surface (the plant canopy area) each second. The unit used to express PPFD is micromoles of photons per square meter per second (µmol/m2/s).
