WebDec 16, 2024 · A 600W LED grow light is shown in the chart above at various distances from the plant canopy. This chart displays light intensity (lux), PPFD (μmol/m-2/s-1 or micromoles per square meter per second), and the light coverage of the canopy. PPFD/PAR changes with the distance of the plant canopy from the light source. WebSep 5, 2024 · Photosynthetic photon flux density (PPFD) measures the amount of PAR light that actually arrives at a givenarea. So the PPFD tells you how much PAR light is hitting each part or each point of the canopy. PPFD is usually tested in a grow tent or laboratory at a fixed height and a fixed area expressed as μMol per meter squared per second (μMol/m2/s).
