What is PPFD? It's a fancy way of saying how much light your plants are getting for photosynthesis.
Photosynthetically Active Radiation (PAR) is the range of light wavelengths essential for plants' photosynthesis.
PPFD (Photosynthetic Photon Flux Density) measures the number of photons in the PAR range hitting a specific area per second, in micromoles per square meter per second (µmol/m²/s). This measurement is crucial for determining if a plant is receiving enough light at a particular spot, ensuring it gets enough light for healthy growth.
In simpler terms, PPFD tells you the intensity of light that actually reaches your plants, which is essential for optimising their growth and health.
