Sustee Refills is a refill for Sustee Watering Gauge which is extremely easy to replace. It comes in 3 different sizes-small, medium and large. You just have to twist-off cap, remove the used core, insert a new core and replace the cap.
Sustee core needs replacements every 6 to 9 months for best results. The core displays blue colour when the plant has enough water and fades to white when it is time to water.
How to use:
- Remove the locking cap by turning it counterclockwise.
- Take out the used inner core and replace it with a new one.
Please check Sustee Water Gauge page if you need the watering checker.
