Dampdruktekort
De onderstaande tabel bevat informatie over de ideale VPD waarden:
| Growth Stage | Ideal VPD Range (kPa) | Notes |
| Seedlings & Clones | 0.4 – 0.8 | High humidity needed, fragile roots, avoid drying out |
| Vegetative Stage | 0.8 – 1.2 | Balanced transpiration, strong foliage and root growth |
| Flowering Stage | 1.2 – 1.5 | Lower humidity to avoid mold, support quality production |
| Night Phase | 0.8 – 1.2 | VPD should stay close to daytime levels to reduce swings and stress. |
