Growth Technology

Alpha Coco Rocks

Coco and expanded clay are both well-proven growing mediums. It has become an established practice, mainly
in the commercial sector, to blend these two materials together and there is a lot to be excited about. The blended
medium has great moisture retention from the coco, but still retains a high level of aeration provided by the clay
pebbles. This blend delivers a superb environment for root growth.
As the materials are professionally mixed, there is no danger of water logging or clumping in the pots and Alpha Coco
Rocks is ideal to use in several different systems.
