What Is PPF?
Photosynthetic Photon Flux (PPF) is the metric used to measure PAR. It is a total count of light energy (in photons) from 400nm to 700nm.
PPF is measured in micromols (μmol). Micromols are 10-6 of a mol (A mol is a unit of measurement). The measurement is classified in time, revealing how many seconds it takes the light to reach the measurement tool. PPF is expressed as μmol/sec.
UV causes plants to produce oils, antioxidant vitamins and flavonoids to protect themselves from the damaging effects of UV. These compounds produce the vibrant colors, smells and tastes of plants.
