PHOTOSYNTHETIC PHOTON FLUX DENSITY (PPFD)
Photosynthetic Photon Flux Density (PPFD)
Photosynthetic Photon Flux Density is the most accurate form of measurement
horticulturists have to determine how much plant-useable light energy there is in a
specific location within a plant canopy. More accurately, PPFD is a measure of the
number of photons in the 400-700nm range of the visible light spectrum (400-700nm
is the range that is useful to plants known as photosynthetic active radiation or PAR)
that fall on a square metre of target area per second. PPFD is measured in micromoles
per square metre per second (μmol/m 2 /s).
