This helpful tool tests moisture levels in garden and container soils. Instantly, the Rapitest Soil Moisture Tester indicates when you need to water your plants, helping you keep your plants hydrated while also preventing over-watering. Simply insert the Soil Moisture Tester into the soil and observe where the indicator falls on a scale of 1-4 (dry-wet). A chart provided lists over 100 plants and their assigned watering number. Water the plant when the needle falls on the number or below.

For indoor and outdoor use. Cleaning pad included. No batteries required.
