Sustee Aquameter, Soil Moisture Meter - Medium

Sustee is unlike any other moisture sensor - you can leave it in the soil and it works for 6 to 9 months without the accuracy rapidly degrading. The inner core will tell you when to water the plant. This multi-award-winning design is maintenance free and works with all types of plants. No batteries required.

• Colour of the inner core changes based on pF values. White means the plant needs watering; blue means it has enough water.
• The inner core needs to be replaced after 6-9 months in order to work optimally. (Refills available here)
• The inner core is made from biodegradable fabric.
• Made in the Japan.

The Medium Sustee Aquameter measures 7.1"(18cm) in length and should be placed within a 7.8"(20cm) radius of your plant.
