- Association Media matric potential and temperature varied inversely with rooting volume.
- Observation The smallest rooting volume showed a twofold fall in root-zone matric potential to −14 kPa.
- Association The smallest rooting volume had lower overall matric potential than the largest volume.
- Observation The root environment had large daily temperature fluctuations of 12°C.
- Association The smallest volume was 3°C warmer than the largest volume.
- Intervention effect Modified hydroponics with frequent watering eliminated matric-potential differences among rooting volumes.
- Intervention effect Modified hydroponics with frequent watering reduced media temperature differences among rooting volumes.
