Do you have trouble figuring out when to water your plant babies? Well, we have the perfect solution! The Sustee 'watering checker' is designed to sit permanently in your troublesome plants, and will change colour when it's time to water. When your Sustee is white, it means your baby is most likely due for a drink - if it's blue, you know your baby is good to go!
Sustee size M is best for pots 12cm to 20cm in diameter.
