General Hydroponics CocoTek Mixed Bricks, case of 24 is no longer available

CocoTek Compressed bricks are composed of low sodium coconut coir and chips. Each brick will expand to about 2.5 gallons when re-hydrated with water. CocoTek Organic Growing Media is ready to use in a Mixed brick (25% chips and 70% coir) or make your own blend by combining the Chip and Coir bricks. The Coir brick provides excellent water retention and the Chip brick improves aeration. A custom mixture of the two creates an ideal growing medium for a specific growing environment.
