CocoTek AB Slabs are ideal for pushing plants to their maximum when using continuous drip applications. When utilizing other methods - like drain and flood - that call for a more absorbent slab, the new AB absorbent slab has superior absorption capacity and is able to retain moisture for a longer period of time. The AB slab's moisture retention is similar to that of standard rock wool, and is achieved through a hollow center filled with loose coconut coir. In fact, users can fill the AB slab with whatever growing medium they prefer.
