Sustee Small Refill
Environmetally friendly and economical Sustee core refills.
The inner core of SUSTEE is made of natural fibers and can be consumed by microorganisms.
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 6-9 months).
