Sustee is a clever tool that will help you know when to water your plants without overwatering.
Simply insert one Sustee into the soil of your chosen potted plant. When you water for the first time, the top of the Sustee will turn bright blue within 30 minutes. This signals that the soil is wet and has received enough water.
As the soil dries out, the top of the Sustee will change it’s color back to white, signaling the soil is dry enough to be watered again.
