How Much Light Does Strawberry Need? PPFD & DLI
Prefers gentle to moderate light and controlled watering without waterlogging.
- Peak PPFD: 400–650 µmol/m²/s
- Peak DLI: 20–33 mol/m²/d
- Air temperature: 18–24 °C
- Relative humidity: 60–75 %
- VPD target: 0.7–1.1 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 | 5–10 mol/m²/d | 14 h | 5.5–6.2 | 0.6–1 |
| Vegetative | 21 | 250–400 µmol/m²/s | 13–20 mol/m²/d | 14 h | 5.5–6.2 | 1.2–1.5 |
| Flowering/fruiting | 45 | 400–650 µmol/m²/s | 20–33 mol/m²/d | 14 h | 5.5–6.2 | 1.5–1.8 |
Watering
Keep soil moist without waterlogging the roots.
