PPFD , or Photosynthetic Photon Flux Density , is a measurement of light density in a given area. Photosynthetically active radiation (PAR) is the range of light wavelengths that enables photosynthesis in plants. The actual range is from 400 to 700 nanometers (nm). Ultraviolet and infrared wavelengths are just below and above each end of the PAR spectrum, and are often included in grow lights because they have specific benefits to plants. 2008-01-11 · PAR is an outside rated light bulb - R is an indoor rated light bulb.
