Canna Aqua Clay Pebbles 45L

Give roots the oxygen they need to thrive

Canna Aqua Clay Pebbles are premium expanded clay aggregate (LECA) made specifically for hydroponics and indoor growing. Manufactured from high-quality baked clay, these lightweight pebbles provide excellent drainage, aeration and root support, creating an ideal root environment. They suit a wide range of systems including flood and drain, drip irrigation, NFT, DWC and recirculating setups, and can also be mixed into soil and coco to improve drainage. Poor drainage and low oxygen around the roots cause slow growth, root disease and reduced yields; these pebbles create air pockets so roots stay oxygenated while excess solution drains freely.

Key Benefits

• Excellent drainage and root-zone aeration to prevent waterlogging
• Strong root development and vigorous, healthy growth
• Efficient nutrient uptake for better flowering and yield
• pH stable and low in soluble salts for a clean root environment
• Reusable after thorough cleaning and sterilisation
• Solid structural support for larger plants in automated systems

Waterlogged roots and slow drainage in your hydro system?

Poor drainage and lack of oxygen around the root zone lead to slow growth, root disease and reduced yields. The pebbles' air pockets let roots access oxygen while excess nutrient solution drains away efficiently, supporting vigorous vegetative growth, healthier flowering and stable anchorage for heavier plants.

How to Use

1. Rinse the pebbles thoroughly with clean water before first use to remove transport dust
2. Fill your pots or hydroponic containers with the rinsed pebbles
3. Place rooted cuttings, seedlings or plants in, ensuring roots are well supported
4. Connect to your hydroponic system and begin feeding with a suitable nutrient solution
5. Maintain the correct EC and a pH of 5.5-6.2 for optimum nutrient uptake
6. After each cycle, wash and sterilise the pebbles before reuse
