CocoTek® is inert, so there’s no more rockwool itch, no more handling questionable fibers, no funky rockwool taste, no need to flush them, and no more disposal nightmare! CocoTek® breaks down on its own in three years. The cubes have been designed with perforated holes to fit rooting plugs. CocoTek® does not wick like rockwool – the 6” high cube is called the “drip cube”. It is 100% organic, made from coconuts and natural rubber so it boasts an impressive water to oxygen ratio while being easy and responsible to use. Coco cubes can be used with ebb and flow systems, but require deeper and more frequent flooding cycles.
