FD Coco Coir is a 5 kg(11lbs), compressed coco coir(pith) block. Harvested from the husks of coconuts, coco coir has many benefits over peat moss. Originally thought to be a waste product, coir is now the leading substitute for peat moss. With coir's growing awareness, many users are realizing that you can also grow 100% in the medium, that is as long as some sort of nutrients are added. A renewable and sustainable medium, FD Coco Coir is superior to peat moss because it holds up to 10x its weight in water. Unlike peat moss, FD Coco Coir does not clump and allows irrigation and root penetration. Because of coconuts high lignin content, FD Coco Coir will not degrade as rapidly as peat moss, allowing for multiple seasons use from just one product. FD Coco Coir can be used 100% as a growing medium, for custom soil mixes, as a potting soil, or for seed propagation. After hydrated, the block will expand to about 2.5 cubic feet of growing medium. FD Coco Coir does not attract insects and is not harmful to pets. WARNING: NOT FOR COMSUMPTION.
