IPPINKA Soil Moisture Meter Sticks - 12-Pack Small Green Refillable Leave-In Aquameter

IPPINKA Sustee Aquameter is a leave-in, refillable soil moisture stick sold in a 12-pack that shows when your indoor plants need water by changing color at the root level.

Designed in Japan and developed in collaboration with Tokyo University of Agriculture, the Sustee Aquameter offers continuous, low-maintenance moisture monitoring for small pots and succulents. Unlike probe meters that must be inserted and removed each time, these slender green sticks remain in the soil to give ongoing visual feedback—white for dry and blue for sufficiently watered—so you can water with confidence and avoid over- or under-watering.

How does the Sustee Aquameter tell me when to water?

The Sustee uses a refillable core that reacts to moisture at the root zone and produces an easy-to-read color change. It’s calibrated for soils that retain water and is suitable for most indoor potting mixes.

• Color indicator: white = needs water; blue = watered
• Senses moisture at root depth to prevent surface misreads
• Refillable core lasts about 6–9 months before replacement

Can I leave these sticks in the soil permanently?

Yes—these are designed as leave-in sensors so you don’t need to remove them after each check. Their compact, maintenance-free design requires no batteries and is environmentally friendlier than disposable probes.

• Leave-in style for continuous monitoring
• No battery or power source required
• Maintenance-free body and replaceable core

What pot sizes and plant types work best with this 12-pack?

The sticks are small (4.7 x 0.4 x 0.3 inches) and intended for narrow pots—ideal for 2, 2.5, and 3 inch containers—but they can be used in other small to medium indoor pots where root-level sensing is needed. They perform particularly well in soil mixes that retain moisture and with small houseplants, including many succulents.

• Recommended for 2–3 inch pots and similar small containers
• Works well with moisture-retentive potting mixes
• Good for succulents and most indoor potted plants

How long will each stick and the refill core last?

Each stick includes a refillable core engineered to respond to soil moisture; each core typically lasts six to nine months depending on conditions. The sticks themselves are durable and built for repeated use, making the kit economical for households with many small pots.

• Core lifespan: approximately 6–9 months
• Durable outer pen designed for long-term use
• Pack of 12 gives multi-pot coverage or seasonal replacements

Who is this for? The IPPINKA Sustee Aquameter 12-pack is made for apartment gardeners, busy plant owners, and anyone caring for multiple small indoor pots who wants a simple, automatic way to monitor soil moisture without batteries or frequent probing. It’s especially helpful for people who grow succulents or keep plants in moisture-retaining mixes and need reliable root-level feedback to fine-tune watering routines.
