Hydrotron Clay pebble's rocks

Hydroton Clay is also a useful additive to both Canna Coco and Cellmax when growing in Pot Culture and also anywhere where extra drainage is needed. It is possible to re-use Clay Pebbles once or twice maximum by cleaning them through with Oxy-Plus. We do not recommend that you re-use clay pebbles more than 2 times as you will definitely notice a drop in yield if you do.

Clay Pebbles are light in weight, do not compact and are completely reusable. They can be cleaned and sterilised after use. They are also inert, pH neutral and contain no nutrients. Because the pellets drain freely and do not hold excessive water, they provide good oxygen levels around the root zone and are particularly suitable for flood and drain systems. They are also used extensively for rose and orchid growing.
