45L Bags Expanded Clay Media – Certified Clean of Contaminants. CANNA Aqua Clay Pebbles have both high porosity and high air content which stimulate the development of strong roots that grip the substrate well. Strong roots mean bigger yields. Aqua Clay Pebbles are inorganic, have a neutral pH value, are fungus free and do not rot. They also are lighter weight and do not hold the heat as gravel does. Long-lasting quality canna clay pebbles are an important investment in your food production system, you will not need to replace these for many years.
