COLOR CHANGE FROM DRY TO WET
- A white indicator means it is time to water your plant.
- After watering, Sustee absorbs moisture at root level, like your plant.
- As the level of absorbed water rises, the indicator gradually becomes blue.
- It takes about 10 minutes to turn completely blue after watering, but the time varies by the type of soil.
- Sustee’s refillable/replaceable cores have a life of about 6-9 months, depending on the type of soil. MB HANA will offer core refills as soon as they are available from the manufacturer and before you need to replace yours (around September 2018).
HOW DOES IT KNOW?
The pF curve between 1.7 and 2.3 is the most effective water moisture level for plants. Below 1.7 root rot is likely and above 2.3 the plant starts to dry out and send roots deeper to find water. Sustee is designed to gradually turn white as the soil approaches a level of 2.3, showing you when the plant really needs water to support healthy root development and helping you to avoid watering too frequently.
