IPPINKA Sustee Aquameter Refills - Bundle of 24 Core Inserts

Bundle of 24 (12 packs of 2) replacement core inserts for medium-sized Sustee watering sticks, ideal for plant lovers and enthusiasts. Easily replace core refills by twisting off the cap, removing the used core, inserting a new core refill, and replacing the cap. The core displays a blue color when the plant has sufficient water and fades to white when watering is needed, prompting replacement every 6-9 months for optimal performance.

This innovative and award-winning product design results from a collaboration between Sustee and Tokyo University of Agriculture, ensuring improved functionality and aesthetics. The main body of the replacement stick is crafted from polycarbonate, while the refill is made of nonwoven fabric treated with preservatives. Each individual stick measures 0.4 x 0.3 x 7.1 inches (medium) and is proudly made in Japan.

Notably, Sustee is a modern Japanese soil moisture sensor that features a minimalist aesthetic to complement the beauty of plants. The blue color indicates adequate soil moisture, while white signifies the need for watering. Have your Sustee turned white? It's time to water! After watering, the insert will turn blue again, signaling sufficient moisture levels.

Sustee is compatible with various plants growing in soils with differing moisture retention levels, including akadama soil, black earth, bark, coco peat, peat moss, and vermiculite. When inserting Sustee, ensure that the Ω mark on the stick is entirely covered and that the transpiration opening is visible if the stick needs to go deeper.

The time taken for the color change depends on the amount of water given and the soil's water retention capacity. When using Sustee for the first time, water generously. The small stick changes color in about 3 minutes, the medium in 15 minutes, and the large in 25 minutes. Consider the various sizing options available, from Sustee core inserts to complete sets, tailored to different pot sizes and diameters. Make your plant care routine easier and more effective with Sustee's reliable and convenient watering sticks.
