Grorox® clay pebbles are a lightweight, completely reusable substrate for hydroponic gardening and food production. Unlike rockwool, Grorox® can be dug into garden soil as a drainage improver when no longer needed without causing pollution. We use them in high volume systems like Aquafarm®, and to support plants in net pot containers in our Aeroflo® and Rainforest® systems.
