Expanded clay pebbles: Quick Overview

Expanded clay pebbles are kiln-fired, porous clay granules used as a clean, inert medium in hydroponics, semi-hydro systems, and as a drainage or aeration component in potting mixes. Their rounded shape leaves open air spaces around roots, while the porous interior holds a small buffer of moisture, helping balance oxygen and water more effectively than dense soil alone. Because they are pH-stable and slow to break down, they suit long-term use in passive hydro, reservoir-based growing, top-dressing, or for opening up heavier substrates that stay wet too long. Rinsed and reused correctly, they offer a low-mess way to improve drainage, reduce compaction, and keep root zones cleaner, airier, and easier to manage during routine watering and repotting in indoor setups.
