Incorrect watering is reported to be the cause of
plant wilting 80 percent of the time.

They wilter because they are not thoroughly watered.
However, too much water leads to root rot more often than you would think.
Japanese farmers say that "it takes three years to learn watering plants properly",
this goes to show, that even professionals struggle.

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.
