Photosynthetically Active Radiation (PAR)
This is NOT a measurement or “metric” like feet, inches or kilos. PAR defines the type of light which is needed to support photosynthesis in plant life.
Photosynthetic Photon Flux (PPF) A measurement of the total light (photons) emitted by a light source each second. PPF tells us how much PAR is emitted by a light source. Measured in “micromoles per second” and expressed as: μmoles/second
Photosynthetic Photon Flux Density (PPFD) A measurement of the light (photons) that reach the target each second. PPFD is measured over a one meter square area in “micromoles per square meter per second” and expressed as μmol/m2/s.
Day Light Integral (DLI) A cumulative measurement of the total amount of light (photons) that reach the target during the photoperiod. DLI is measured over a one meter square area in “moles per square meter per day” and expressed as mol/m2/d.
