How Much Light Does Basil Need? PPFD & DLI
Likes heat and frequent watering. Prune the top to make it bushier.
- Peak PPFD: 350–600 µmol/m²/s
- Peak DLI: 14–22 mol/m²/d
- Air temperature: 22–28 °C
- Relative humidity: 50–65 %
- VPD target: 0.8–1.2 kPa
- Do not leave the substrate dry for more than 2 days
