Daily Light Integral – DLI – [mol/m²d]

Daily Light Integral Daily light integral (DLI) describes the number of photosynthetically active photons (individual particles of light in the 400-700 nm range, PAR) that are delivered to a specific area over a 24-hour period. This variable is particularly useful to describe the light environment of plants. Source: Wikipedia – DLI More about PAR One day with LED…
