Leca Clay Pebbles – 10L & 50L Bags

Take full control of root-zone conditions with LECA® Expanded Clay Granules, a professional-grade growing medium engineered for hydroponics, container gardening, terrariums and soil conditioning. Fired at 1200 °C, the clay “pops” into rigid, lightweight spheres whose micro-bubbled, honeycomb interior balances air and water like no other substrate. Because LECA® is pH-neutral, sterile and insect-resistant, it delivers predictable performance over multiple grow cycles while saving irrigation water and preventing compaction. Choose between intact granules for maximum drainage or fragmented granules for higher moisture holding and rapid root branching—both supplied in convenient 10 L or economy-size 50 L bags.

Key Features

• ISO-Certified Consistency – Uniform granules manufactured to stringent standards for repeatable results.

• Optimised pH Neutrality – Will not shift nutrient solution chemistry, ensuring stable EC and pH.

• Lightweight & Reusable – Easy to handle, transport and sterilise; resists crushing or breakdown.

• Superior Root Oxygenation – Inter-granular gaps and internal porosity keep oxygen levels high, preventing root rot.

• Water-Saving Performance – Retains up to 20 % of its volume in moisture while preventing waterlogging.
