TopMix Coir Products

Coir substrate has a variety of uses, depending on the way the coconut husk is processed. It can be divided into three forms: Husk Chips (HC), Coir Pith (CP) and Blend.

Husk chips are produced by cutting fresh green husk into sleeves and chipped afterwards.

Coir pith is fine material combed off the coconut fibres.

Blend is the whole husk ground to form a combination of chip and pith.

Preferred Coir - Washed Unbuffered Coir
