Abbreviation for Daily Light Integral. The total amount of photosynthetically active radiation (PAR) that a plant receives over the course of a day. It’s measured in moles of photons per square meter per day (mol/m²/day) and indicates the total quantity of usable light (within the 400-700 nanometer range) that plants receive for photosynthesis. In cannabis cultivation, optimizing the DLI is crucial for ensuring healthy growth, high yields, and efficient light usage in both indoor and outdoor environments.

Once I started tracking DLI I realized my plants were getting way less light than I thought they were.
