Natural clay composition for excellent oxygenation and drainage.

Grorox clay pebbles are a light and completely re-usable substrate for hydroponic gardening and food production. Unlike rockwool, Grorox can be dug into garden soil as a drainage improver when no longer required without causing pollution. We use them in large volume systems like the CultiMate® L, and to support plants in net pot containers in our GrowStream® and Rainforest® systems.
