| Location | Useful observation | Do not assume |
|---|---|---|
| Substrate | Preparation record and development through the bag | A wet casing proves adequate substrate moisture |
| Casing | Uniformity, physical condition and watering history | The room humidity reading describes water in the layer |
| Room and crop surface | Air distribution, condensation and pin condition | Higher humidity always solves a moisture problem |
