Coconut Coir is the coarse fibers from a coconut husk. Coir fibers are found between the hard, internal shell and the outer coat of a coconut. The individual fiber cells are narrow and hollow, with thick walls made of cellulose. They are pale when immature, but later become hardened and yellowed as a layer of lignin is deposited on their walls. These fibers are harvested and heavily compressed into convenient coir bricks. Coconut coir is a 100% natural and renewable resource.
Compared to peat it is not acidic, coir has a near ideal pH and is easier to work with. It retains more water than peat, which is why it is a good choice for a mushroom bulk substrate. It is free of bacteria and fungal spores and produces good results without the environmental damage caused by peat mining.
Compressed coir bricks are easy to handle and store. They are disease resistant and have an excellent air space and water retention capacity. Good coconut coir is pH Neutral and holds 7 times its weight in water.
Recipe Tek to prepare coir like a pro
1kg of dry compressed coir normally soaks up 12L of water. Use an insulated cooler box, add 1kg of compressed coir and 10L of boiling water. Leave to cool naturally and voila. Hydrated pasteurized coir ready for use.
