What is ppfd and how it affects plants growing?

Uncategorized
PAR (photosynthetically active radiation) is a value identifying the type of light or light spectrum to which plants respond during photosynthesis. Photosynthesis is the process through which plants convert light energy into chemical energy. This converted light is what energy plants use for growing and blossoming. In plants, light primarily reacts with chlorophyll a and b. Now let us understand what is ppfd? Normally we can measure the light falling on the plant in the PAR range, which is expressed as PPFD (Photosynthetic Photon Flux Density) in micromoles per meter per second, mol/sm2. In the past, light values in greenhouses were always expressed in lux. Photon Flux in Photosynthetic Organisms (PPF) The entire amount of light produced by a light source in the PAR range per second is referred as…
