Leca Stone - 45 Liters

Expanded Clay Pebbles for Hydroponics, Aquaponics & Container Growing

LECA Stone (Lightweight Expanded Clay Aggregate) is a premium hydroponic growing medium made from natural clay that has been kiln-fired at high temperatures to create lightweight, porous clay pebbles. These expanded clay stones provide excellent aeration, drainage, and root support, making them a popular choice for hydroponic systems, aquaponics, greenhouse production and container growing.

The porous structure of LECA stones allows them to absorb moisture and slowly release it back to plant roots while maintaining air pockets that promote strong root development and prevent waterlogging. This balance of moisture retention and oxygen availability helps support healthy, vigorous plant growth in hydroponic environments.

Because expanded clay pebbles are inert, pH-neutral, and reusable, they offer growers long-term value and precise control over nutrient management when used with hydroponic fertilizers.

Key Features

• Excellent Drainage & Aeration
  The porous structure of expanded clay pebbles allows water to drain freely while maintaining air pockets around plant roots, reducing the risk of root rot and improving oxygen availability.
  
• pH Neutral & Inert Growing Media
  LECA stones are chemically inert and typically maintain a neutral pH, helping growers maintain precise control over nutrient solutions in hydroponic systems.
  
  
• Moisture Retention for Consistent Growth
  The internal pore structure absorbs water and nutrients, gradually releasing them back to plant roots for consistent hydration.
  
  
• Reusable & Long-Lasting
  Expanded clay media does not break down over time and can be washed, sterilized, and reused across multiple growing cycles.
  
  
• Versatile Growing Applications
  Suitable for a wide range of hydroponic systems including bato bucket systems, drip irrigation, flood-and-drain, aquaponics, and container growing.
