Controlled-Environment Light Planner
Quantify natural Daily Light Integral (DLI), greenhouse transmission, and supplemental PPFD setpoints using NASA POWER climatology and crop-specific research.
Key equations
- Outdoor DLI = NASA irradiance (kWh·m⁻²·d⁻¹) × 1.65 (μmol to mol conversion).
- Greenhouse DLI = Outdoor DLI × transmission (glazing × structure × cleanliness × shade).
- Supplemental PPFD = DLI deficit × 10⁶ ÷ (photoperiod [h] × 3600).
