SUSTEE Aquameter

Incorrect watering is reported to be the cause of plant wilting 80 percent of the time.
Sustee is a "watering checker" that can tell you when to water your plant.
Just stick this fail-proof device in your plant pot, and you'll be at ease for quenching your plants' thirst.
 
The first moisture checker with pF indicator for your home.
For the first time ever, a home-grade moisture checker has been equipped with a pF indicator (available water capacity).
This way the root's ability to absorb water - or the plant's "thirst" becomes visible (patented in Japan, No. 5692826).

The high quality of SUSTEE prevents root rot caused by improper watering.
To better our product we keep testing and researching in cooperation with the Tokyo University of Agriculture and farmers.
