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.

Before I got these I was alternately over watering or under watering. Now my plant is doing well. You will have to replace the wick inside periodically.

Instead of sticking my fingers into the soil to check the moistness, I simply look at the marking on the stick now! The blue marking lets me know when it’s time to water again. And they are small enough they don’t stick out like a sore thumb as other products do. I will definitely be ordering more for all my household plants.

These are my favorite water checkers. My plants are looking perky since I started using them. I'm not very good at how often to water & these are fantastic. You leave in soil so it convenient to check whenever & they do turn white in dry soil.

I got two only one is working. One that doesn't work has water and still shows no water. But another one works with no issues.

These water indicators were supposed to last 6-9 months. I got 2 months of use out of them and they quit working. Not a very good product. They offer refills but why buy a refill for a product that didn't work in the first place?

These aquameter moisture monitors are the black thumb gardeners best friend! I know, I am one of them. My indoor plants are now looking much better and the mentors help me to know when to water. Recommend to everyone
