Light calculator
Estimate PPFD and daily light integral (DLI) for your tent and LED wattage. These are approximations — actual values depend on fixture efficiency, hang height, and reflectivity.

Fine for seedlings. Increase for veg and flower.
Target DLI: seedlings 15–20, vegetative 25–35, flowering 35–45 mol/m²/day. Use a PAR meter for accurate readings. Raise or lower your light to adjust PPFD.
