WebPhotosynthetic Photon Flux Density (PFFD) measures light’s intensity or the number of photons in a given amount of light. The unit used is micromoles per meter squared per second, or umol/m2/s. PFFD is crucial for plants because each species has an optimal level for efficient growth. WebWe have therefore developed the calculator below which allows for approximate conversions between lux and PPFD based on some assumptions about the light source's SPD. To improve the approximations for your particular light source, select the SPD that most closely resembles that of your light source.
