Coconut products are increasingly gaining importance as feedstock in German substrate production, because they have a very stable structure and drain well. Plants can even be grown in 100% coco coir if the coco coir quality is high.
Coconut products are mainly imports from India and Sri Lanka. The outer shell of the coconuts (husk; mesocarp) is used as feedstock. This material is a by-product of copra harvesting on coconut plantations. Copra is the white flesh of the coconuts. Fibre mills separate the fibres from the outer shell and process them to make ropes and yarns. Specialised companies use the residues from the separation process (coco pith and short fibres) as feedstock in substrate production. These companies also first crush and then sift the dried husks to make coco chips.
