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.
