Upgrade your hydroponic setup with Radongrow LECA Clay Balls (Hydroton) — lightweight expanded clay aggregate that gives roots the perfect balance of moisture and air. Now available in three pack sizes (5 Litre, 30 Litre, and 50 Litre) to suit hobby growers and larger setups alike, ideal for ebb-and-flow, DWC, aquaponics, and a wide range of soilless growing systems.

Made from 100% natural clay, these pebbles are inert and pH-neutral with no added nutrients, so you stay in full control of your nutrient solution. Their porous structure delivers excellent aeration and steady water retention, helping roots breathe while staying evenly moist for healthier, more vigorous growth.

What it solves: growing media that compacts or holds too much water can starve roots of oxygen. Hydroton's stable, free-draining structure prevents waterlogging, supports strong root development, and keeps plants anchored — without the mess of soil.

An eco-friendly choice, the clay balls can be cleaned, sterilised, and reused season after season, making them a cost-effective, sustainable growing medium.

Choose your size: 5 Litre (approx. 1.5 kg) for small setups, 30 Litre (approx. 9–11 kg) for hobby growers, or 50 Litre (approx. 16–18 kg) for larger systems. pH-neutral (7–8), inert, reusable, lightweight expanded clay.
