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

Effortless moisture awareness for thriving houseplants

The Sustee Aquameter is a leave-in soil moisture sensor that stays planted in your pot, offering ongoing visibility into your plant's moisture needs. Unlike meters that require removal after each check, this design sits in place, helping you keep hands clean and soil undisturbed as you watch for color cues.

In the set of five, you receive white, refillable sticks with a durable core. Each stick is designed for long life and simple maintenance—no battery required. Independent testing and collaboration with Tokyo University of Agriculture helped refine both the form and the function, ensuring the indicator remains legible as it ages and in varying soil types.

How to use and what to expect

Insert a stick into your pot (recommended for sizes 3.5 to 6 inches). The device uses a color indicator to reflect soil moisture: white signals that water may be needed, while blue shows that water has been added. The indicator is designed to be intuitive at a glance, making it easier to manage watering tasks on a schedule—even on busy days.

• Maintenance-free operation with no battery to replace
• Leave-in design minimizes soil disturbance during checks
• Replacement cores extend usage without discarding the entire unit
• Compact, unobtrusive form that fits standard pot sizes

The set is crafted in Japan and brings together thoughtful engineering and practical design. The water indicator adapts to different soil types, offering a simple, visual cue that can help you gauge when to water. While not a medical or plant-health guarantee, many users find it helpful as a planning tool for routine care. With five sticks in each package, you can equip several pots or reserve extras for future plantings.
