GROW!T® Clay Pebbles
- 10L Bag of 4mm - 16mm Pebbles
Made from 100% natural clay. They are clean, pH stable, and offer great aeration and drainage in hydroponics, especially in flood and drain, deep water culture, and drip feed systems. Due to their non-uniform structure and large surface area, they offer the ideal environment to foster beneficial bacterial growth around the root zone, leading to naturally healthier plants. Aka Leca.
