How To Calculate PPFD From DLI
When it comes to indoor plant cultivation, understanding light intensity is crucial for promoting healthy and vigorous growth. PPFD (Photosynthetic Photon Flux Density) and DLI (Daily Light Integral) are two essential metrics that help growers assess the amount and quality of light their plants receive.

Conversion – Lux to PPFD
The conversion from Lux to PPFD (µmol m-2 s-1) varies under different light sources. For a complete discussion please see the reference listed below.

What Is The Absorption Theory ?
Plants are the only photosynthetic organisms to have leaves (and not all plants have leaves). A leaf may be viewed as a solar collector crammed full of photosynthetic cells. The raw materials of photosynthesis, water and carbon
