Pure Clay Pebbles 60/40

Pure Clay Pebbles 60/40 is a high-performance, inert substrate blend ideal for hydroponic, aeroponic, or hybrid setups. Made from 60% rinsed, pH-neutral clay pebbles and 40% organic coco fibers, it delivers excellent drainage, high oxygen levels, and stable moisture retention that’s perfect for promoting aggressive root development and rapid, healthy growth. The pebbles give this substrate structure and airflow, while the coco adds the perfect amount of water-holding capacity to help maintain a balanced root zone. Especially beneficial for high-frequency irrigation setups, it’s naturally sterile, compaction resistant, and free from added nutrients for full control over your feeding strategy. If you’re going for a full organic growing approach and want a substrate with added biological activity, Pure Professional Organic is worth checking out. If you're transitioning into a lighter, more nutrient-active medium, Pure Superior Light Mix is an enriched alternative that delivers strong growth during veg.
