The 10 liter bag of Euro Pebbles Plagron clay balls is an inert substrate that uses pure clay without salt. The balls are fired in an open oven, which gives them their special irregular shape.

We recommend rinsing the balls properly before use (some may be broken due to transport).

These clay balls are ideal for recirculating hydroponic systems, they can be used with potting and repotting substrate. They will considerably help the structure, drainage and even the supply of air to the roots.

Reusable clay balls, rinse with water before reuse.
