How Much Light Does Aromatic herbs (basil, mint...) Need? PPFD & DLI
Diverse aromatic herbs requiring regular trimming and good aeration.
- Peak PPFD: 250–450 µmol/m²/s
- Peak DLI: 12–20 mol/m²/d
- Air temperature: 18–24 °C
- Relative humidity: 45–60 %
- VPD target: 0.8–1.2 kPa
- Do not leave the substrate dry for more than 3 days
Targets per growth stage
| Stage | From day | PPFD | DLI | Photoperiod | pH | EC |
|---|---|---|---|---|---|---|
| Seedling | 0 | 100–200 µmol/m²/s | 6–12 mol/m²/d | 16 h | 5.8–6.4 | 0.8–1 |
| Growth | 14 | 200–400 µmol/m²/s | 10–16 mol/m²/d | 16 h | 5.8–6.4 | 1.2–1.6 |
| Mature | 30 | 250–450 µmol/m²/s | 12–20 mol/m²/d | 16 h | 5.8–6.4 | 1.6–2 |
Watering
Maintain consistent hydration. Herbs wilt quickly in drought.
