General Hydroponics® CocoTek® Bale Organic Growing Medium
The CocoTek® line of organic growing media consists of three different types of compressed coco coir. This high-quality, low-sodium growing media is an environmentally friendly alternative to sphagnum peat moss. When hydrated with water, CocoTek® blocks rapidly expand. The natural coir block contains only coconut pith and fibers. Great for water-holding capacity, these materials also provide plenty of aeration and drainage.
