Why should we pay more attention to PPFD instead of LUX when testing plant lights
PPFD, which stands for Photosynthetic Photon Flux Density, is a measure of the number of useful photons received by plants per unit area per second.
Simply put, plants rely on photosynthesis to grow, and PPFD tells us how much light the plant actually receives to participate in photosynthesis. The higher the PPFD value, the more photons the plant can absorb for photosynthesis.
