Introducing SUSTEE: SUSTEE is a modern Japanese soil moisture sensor. The blue color indicates that the soil has enough water, while the white color indicates that the plant needs watering. SUSTEE features a minimalistic aesthetic that complements the beauty of your plants.

Understanding SUSTEE Color: If your SUSTEE turns white, it is time to water your plants. After watering, the white insert will change to a blue color, indicating that there is now adequate water in the soil.

Compatibility with Various Soils: SUSTEE can be used with a wide range of plants that grow in soils with varying levels of moisture retention. This includes akadama soil, black earth, bark, coco peat, peat moss, and vermiculite.

Proper Insertion Depth: When inserting SUSTEE, ensure that the Ω mark on the stick is fully covered. Additionally, make sure that the transpiration opening is visible if the stick needs to be inserted deeper.

Timing and Sizing: The time it takes for the color to change depends on the amount of water given and the soil's water retention level. For initial use, water generously. The small stick changes color in approximately 3 minutes, the medium stick in 15 minutes, and the large stick in 25 minutes.

Product Sizing and Customer Reviews: SUSTEE Small, Medium, and Large sizes are available, each suitable for different pot sizes and diameters. The set includes 36 small SUSTEE Core Inserts. Customers have rated the product highly, with an average of 4.2 to 4.4 out of 5 stars.

Ease of Use: The core refills are easy to replace, simply twist off the cap, remove the used core, insert the new core, and replace the cap. The core displays a blue color when there is enough water and fades to white when it is time to water. This set includes 2 replacement sticks for use with small refillable Sustee Aqua meter, with each core recommended to be replaced every 6-9 months for optimal results. The award-winning design of SUSTEE was developed in collaboration with Tokyo University of Agriculture to enhance both the design and functionality of each stick.
