01What is PAR ?

Photosynthetically Active Radiation PAR defines the type of light which is needed to support photosynthesis in plant life

02What is PPFD?

Photosynthetic Photon Flux Density PPFD is measured over a one meter square area in “micromoles per square meter per second”ans expressed as μmole/㎡/s

03What is PPF ?

Photosynthetic Photon Flux PPF tells us how much PAR is emitted by a light source Measured in “micromoles per second”and expressed as μmoles/second

04What is μmol/J?

Stands for micromole per Joule μmol/J It is a measurement to determine how efficient a light is at converting electrons into photons
