GROW LOGIC CALCULATOR
Match your room to the right light.
Enter your dimensions and crop. We'll calculate the PPF, recommended wattage, and target DLI — then filter the directory to fixtures that meet your spec.
How this works
- PPF needed — calculated from your room area and crop's photosynthetic demand.
- Recommended wattage — based on a 2.5 µmol/J efficacy baseline. Verified fixtures often beat this; expect 15-25% lower draw on Samsung LM301H boards.
- Sponsored lights appear first in the matched listings below.
