Coco coir is substrate made from coconut fibres and is the base for many substrates due to it being 100% biodegradable and highly versatile.
You can mix up a very simple substrate to house pretty much anything short-term due to it being chemically inert and it makes up a lot of plant soils as well due to it being so high in carbon.
Coco coir allows for a fantastic air/water exchange for fast drainage and is completely evasive to microorganisms - meaning it can hold water without festering.
 
Our coco coir is responsibly sourced and is completely sterile and safe to use straight away!
