ppfd for vegetables

Every crop has an ideal PPFD that it requires for optimal growth. PPFD is the number of micromoles of light that hit any given square meter of your crop each second. PPFD stands for ‘Photosynthetic Photon Flux Density.’ PPFD is a measurement of light intensity, and it says how many light photons that fall within the PAR-range (expressed in micromoles) hit a given square meter per second: μmol m(-2)s(-1). Yes. 1 PPFD, or photosynthetic photon flux density, is a spot measurement of light. O PPFD, or Photosynthetic Photon Flux Density, is a measurement of light density in a given area.
