Finally! A moisture meter that doesn't look like its been hanging out in a lab for the past twelve years.
The Sustee moisture meter measures the soil moisture retention (pF) curve and lets you know if your houseplant is due for a drink or if you should put that watering can away!
Just like a plant, it draws up water and allows it to evaporate through tiny transpiration holes in the display window. The Sustee will turn blue when water levels are all good and white when its time to give your plant a drink.
