Coir

Coir (from Malayalam kayar, cord) is a coarse fibre extracted from the fibrous outer shell of a coconut.

In horticulture, coir is recommended as substitute for peat because it is free of bacteria and fungal spores, and is sustainably produced without the environmental damage caused by peat mining.

I hope I can find a local vendor. I want to try this coir.
