Schedule and VPD targets
Vapour pressure deficit targets by stage, measured from leaf temperature rather than air temperature. The same bands ChloroFile charts against.
| Stage | When | VPD target |
|---|---|---|
| Seedling | Weeks 1-2 | 0.4 - 0.8 kPa |
| Vegetative | Until you flip | 0.8 - 1.2 kPa |
| Early flower | Flower weeks 1-3 | 1.0 - 1.5 kPa |
| Late flower | Flower weeks 4-10 | 1.2 - 1.6 kPa |
Counting from the flip, expect to harvest between week 9 and week 10.
