Grorox® 1 L

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 Aquafarm®, and to support plants in net pot containers in our Aeroflo® and Rainforest® systems.
