Activated carbon (3 litres)
This product is currently sold out.
Activated carbon pellets (also known as activated charcoal) filter out any harmful chemicals, metals, mould and other nasty things you don't want in your terrarium or houseplant soil. Add it just above the drainage layer of your terrarium or mix it into your plant soil to filter out the bad stuff.
By adding activated carbon to the soil you are protecting the root system against possible pests & moulds. While it isn’t 100% protection, it does offer an extra safety barrier. It also creates a more gritty & airy texture preventing too much moisture in the soil.
