Meet SUSTEE
SUSTEE is a modern, Japanese soil moisture sensor. The blue color indicates that there is enough water in the soil, and the while color indicate that plant is in need of watering. SUSTEE features a minimal aesthetic that doesn't take away from the beauty of your plants.
SUSTEE
Color
Has your SUSTEE turned white? That means it is time to water! After watering, the white insert will change to a blue color. This indicates that there is enough water in the soil.
Soil
SUSTEE can be used with almost all plants that grow in soils with a certain level of moisture retention. This includes akadama soil, black earth, bark, coco peat, peat moss and vermiculite.
Insertion Depth
When inserting SUSTEE, please ensure that the Ω mark found on the stick is entirely covered. Please also make sure that the transpiration opening is visible if the stick is needing to go deeper.
Time
The time it takes to change color will depend on the amount of water given and the water retention level. When using SUSTEE for the first time, please water generously. The small stick takes approximately 3 minutes, the medium 15 minutes, and the large 25 minutes.

These are awesome! They are about half of the size of an ink pen and turn blue when the soil is moist, fading to white as it dries out. Easy and accurate way to maintain soil moisture.

Testat i sätta ner i flera krukor och ingen ändrar färg efter vattning. Trots att jorden fortfarande är tydligt blöt även dagen efter så förblir stickorna samma vita färg som när jag tog dem ur paketen. Beställde 5pack av både S och M ingen fungerar.

Doesn't work as it should. Just use the chopstick method instead

Working very well at the beginning. After 6 to 9 months they stated stopped working one by one (no reaction to watering). Within 9 months all of them stopped working. For this price it's a total rip off.
