Daily Light Integral (DLI) Calculator
The DLI Calculator helps you determine the total amount of light (in mol/m²/day) a plant receives based on your light’s PPFD and the number of hours it stays on.
Enter your light intensity and duration:
How it Works
- Enter the average PPFD (Photosynthetic Photon Flux Density) of your grow light.
- Enter how many hours the light runs each day.
- Click "Calculate DLI".
- The script converts PPFD and light duration into DLI in mol/m²/day.
What is DLI?
DLI (Daily Light Integral) measures the total light plants receive in a day. It's calculated in mol/m²/day and is a crucial factor for plant growth.
What is PPFD?
PPFD stands for Photosynthetic Photon Flux Density. It measures the amount of light (in µmol/m²/s) available to plants at a specific point.
