Description

The inner core of SUStee is 100% natural, made of non-woven cotton and will be consumed by microorganisms over time.

The state of the soil is a factor, but it can be said that the core has to be replaced when it stops turning blue after watering (approximately after 6-24 months).

How do I know when to replace the inner core?
– Take the SUStee device out and verify the opening at the bottom. If the inner core has decomposed, it is time to replace it with a new one. – The inner core should be replaced when the device stops reacting, even if it is not entirely gone.

After long time use, the device might react poorly due to soil components or other fine particles deposited onto it.

Approximate inner core replacement times for different soil types:
– Organic culture soil: 6 to 9 months
– Inorganic soil: 9 to 12 months
– Hydroculture: 1 to 2 years
– Bog moss/bark: 1 to 2 years
– Peat moss: 1 year

Changing the core is done in two simple steps.
It is easy and can be done by anyone.
