This easy-to-use moisture indicator by Sustee helps you keep track of the watering needs of your plants. Perfect for transplanted Click & Grow plants or other medium and large-sized houseplants.
The main cause of killing houseplants tends to be overwatering not underwatering. This indicator helps to avoid both. To get help with overwatering - just water the plant only when the indicator turns from blue to white. And when you stick it in soil and it does not turn even light blue in around half an hour, that means your plant already needs water.

FAQ
When does it turn from blue to white?
When soil moisture is 20%-25% at the bottom of the pot - that's also an optimal time to water.
Can it be used for plants that need drying out, such as succulents?
Succulents need soil to dry out (about 10% soil moisture) between waterings. So you can wait a few more days before adding water, after the indicator turns white.
What if the indicator doesn’t change color after the first time inserting it into the soil?
Soil is probably quite dry. Try watering from the top of the soil so the stick will have a good contact with the substrate and enough moisture to change the color.
When will I know that the inner core needs changing?
We recommend replacing it as given in the average lifespan table below to avoid the situation that the core is already depleted and the indicator doesn’t show an accurate moisture level. It’s okay to take Sustee out of the soil occasionally and check the condition of the core.
