Sustee size L is best for pots more than 18cm in diameter.
Are you tired of not knowing when to water your plants? Do you stay up at night worrying that you’ve over watered your plants? Or Under watered your plants for that matter?
Did you know Incorrect watering is reported to be the cause of plant wilting 80 percent of the time.
Thats right, they wilt because they are not thoroughly watered, BUT 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.
Enter Sustee, the worlds first home-grade moisture checker equipped with a pF indicator. You don’t need to be a professional, Sustee device absorbs moisture at the root level, just like your plant, then the level of absorbed water rises, the indicator gradually becomes blue.
After anywhere from 5-30 minutes your Sustee pen will turn blue, indicating your plants is sufficiently watered. At that point just wait till it turns white again, and its time to water!
Good Bye sleepless nights!
