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).
We guarantee that the inner core will last at least 6 months.
After long time use, the device might react poorly due to soil components or other fine particles deposited onto it.
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.
Remove SUStee from the pot and follow the instructions below. If dirt has accumulated inside SUStee clean it before you insert a new core.
Remove the lock cap by turning it counterclockwise. Take out the used inner core and replace it with a new one.
Make sure you replace all components in a single operation:
It is rare but possible that the transparent straw is left behind inside the main unit. If this happens, simply remove it with a pair of tweezers.
Remove the top screw cap and look inside to make sure none of the used core material is left behind.
Keep the refill in the inner bag of the product package until just before use. Once taken out of the bag, the refill’s core material may discolour.
*Discoloration won’t, however, affect the refill’s quality and effect.
*Please make sure that your baby or toddler doesn’t put SUStee in his/her mouth. It is not dangerous, but the taste is not nice either.
