Sustee Aquameter Set of 5 — Large Green Plant Soil Moisture Sensor

Meet Sustee Aquameter, a leave-in soil moisture sensor pen designed for ongoing plant care. This set includes five green refillable sticks and a durable, battery-free core, so you can monitor moisture without removing the device after each check. Crafted in Japan with input from Tokyo University of Agriculture, the Aquameter blends thoughtful design with practical use for home and desk plants alike.

The indicator color changes with soil moisture: white signals that your plant needs water, blue signals it has just been watered. With the stick permanently in the soil, you can quickly assess the status at a glance, keeping your plants hydrated at the right times.
