- Measures moisture at root level. Used to prevent over and under watering.
- Includes scale that ranges from 1 (Very Dry) to 10 (Just Watered Wet). Re-water at level 3 for most Bonsai trees.
- IMPORTANT: Wipe clean and dry after each use for accurate readings. DO NOT leave in soil between uses or as a gauge. Meter measures electrical impulses in the soil and will not respond to water alone (as in a glass).
