How Much Light Does Sage Need? PPFD & DLI
Mediterranean herb. Its growth stops responding to light at about 16 mol/m²/d, and it prefers it a little drier than other herbs.
- Peak PPFD: 210–275 µmol/m²/s
- Peak DLI: 12–16 mol/m²/d
- Air temperature: 20–27 °C
- Relative humidity: 40–60 %
- VPD target: 0.9–1.3 kPa
- Do not leave the substrate dry for more than 5 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 | 6–6.8 | 0.8–1.2 |
| Mature | 45 | 210–275 µmol/m²/s | 12–16 mol/m²/d | 16 h | 6–6.8 | 1–1.6 |
Watering
Let the top of the soil dry between waterings; constantly wet roots rot.
