Coir Pith material is compressed at a 5:1 ratio by a hydraulic pressing machine to produce a 5 kg block, which expands up to 75-80 litres by its volume. 5 kg blocks are mostly used in large volumes to prepare plant-based substrates with a mix of perlite, Sphagnum peat moss etc. Coir Pith has the characteristics to mix with any other substrates to give better yield in the plantation.
