Sustee Aquameter Plant Moisture Sensor (Set of 2): Leave-in soil moisture sensor
The Sustee Aquameter takes the guesswork out of watering your houseplants. Designed for busy plant parents, it stays in the soil to give you a constant read on moisture levels at the root zone. No more digging around with your fingers or pulling out a meter every time.
The large size fits pots 6 to 12 inches wide. Simply insert the stick, and the indicator turns white when your plant needs water and blue when it's hydrated. The refillable core lasts 6–9 months before replacement. Developed with Tokyo University of Agriculture, this battery-free tool is perfect for consistent care—especially if you tend to overwater or underwater your greenery.
Keep your hands clean and your plants happy. Set of two green sticks included.
