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.
"I don't want to make any watering mistakes that kill my plants."SUSTEE was born out of this common desire.Core refills for replacement are also available.
