Sustee Aquameter Set of 5 – Leave-In Plant Soil Moisture Sensor (White, Small)

Overview

The Sustee Aquameter Set of 5 offers a low-effort, hands-free way to track soil moisture for small pots and compact plants. The leave-in sensor remains in the soil, providing continuous insight as you go about your day. This setup is especially convenient for tiny succulents and other small houseplants where precise hydration can be tricky to judge by eye.

Key dimensions and suitability

Designed for small containers, the sensor’s compact form fits pot sizes around 2 to 3 inches in diameter. Its slim profile helps minimize soil disturbance, making it ideal for tight spaces like shelves, windowsills, and desks where you want a discreet, always-on monitoring tool.

• Dimensions: 0.4 x 0.3 x 4.7 inches (small)
• Intended for pot sizes of 2, 2.5, and 3 inches
• Ideal for small succulents and other compact houseplants

What’s in the box

• Five refillable Sustee watering sticks (white) with replaceable cores
• A moisture meter that can stay in place for ongoing soil monitoring
• Longer-term value: each stick lasts approximately 6–9 months with normal use

How the color indicator helps you

The plant water indicator changes color based on soil moisture, giving you a quick visual cue. White indicates the plant may need water, while blue suggests the soil has recently been watered. This simple color language can help you build a habit without guesswork.

Design, collaboration, and reliability

Sustee collaborated with Tokyo University of Agriculture to refine the design and function of each stick, aiming for smooth operation and dependable performance. The result is a compact, low-maintenance sensor that supports consistent care across daily routines.

Usage ideas and outcomes

Imagine a sunny windowsill full of small pots. You can insert the Aquameter once and leave it in place, reducing soil disruption while keeping a steady eye on moisture trends. While it may not replace a grower’s intuition, it offers a practical data point you can act on—especially for plants that like steady, moderate watering.

• Keep moisture trends visible over time to guide watering decisions
• Support small plants that benefit from careful, regular hydration

Care and maintenance tips

When a refill is needed, replace the core in the sticks and reinsert as directed. The white-to-blue color cue helps you observe patterns across weeks, letting you adjust care without removing the device from the soil.
