This pen-like device tells you when your potted plants need water. It takes away the risk of over-watering or under-watering (one of the main reasons for plant death) and provides an accurate reading of how much moisture is available to the plant.
Simple to use. Insert it into the pot to below the small arrows. When it displays white, your plant requires water. When it displays blue, your plant has enough water. It's that simple. Instructions are included. No batteries are required.
3 sizes available and 2 colours. Large for your largest plants, small for your smallest plants.
Made in Japan. The Sustee lasts approx 9 months and can be refilled. Refills (made from degradable paper) are available from us.
