Key Features & Benefits

  • Strong Root Support with Excellent Aeration: Each clay pebble is highly porous and creates generous air pockets when filled in a pot or hydroponic tray. This ensures roots receive ample oxygen while preventing waterlogging, contributing to healthier root systems and improved overall growth.
  • Neutral & Inert Medium: Made from low-salt clay, the pebbles are pH-stable, non-reactive and free from salts, safe for nutrient solutions and ideal for recirculating hydro systems or controlled feeding programmes.
  • Excellent Drainage & Water Management: The spherical shape and inter-pebble voids facilitate quick drainage and prevent water stagnation, reducing risk of root rot, overwatering, or anaerobic zones around roots.
  • Reusable and Durable: As an inorganic, fungus-free medium, the pebbles won’t degrade over time; you can rinse, sterilise and reuse them across multiple grow cycles, making them economical and sustainable.
  • Versatile Across Growing Systems & Media: Whether you run hydroponics, aquaponics, coco, or soil-based pots, Aqua Pebbles work well as a standalone inert medium or as part of a mixed substrate, giving flexibility for different grow methods.

How to Use

  • Rinse Before Use: Always rinse the pebbles thoroughly before first use to remove any dust or loose particles, this prevents potential blockages in drip systems or flood trays.
  • For Hydroponics (ebb & flow, DWC, drip, NFT, etc.): Use pebbles as the main substrate.
  • For Pot Culture: Blend pebbles with coco, soil or other substrates, or use them as a drainage layer at the bottom of pots for improved aeration and drainage.
  • Ensure Good Drainage & Airflow: The structure of Aqua Pebbles encourages drainage and airflow. Pair with suitable irrigation and drainage systems for best results.
  • Reuse with Proper Cleaning: After harvest, wash and sterilise pebbles if reusing. Because they’re inorganic and durable, they hold up well across cycles.

Frequently Asked Questions (FAQ)

Are Canna Aqua Pebbles suitable for hydroponic systems?
Yes, they’re ideal for all closed hydroponic setups (ebb & flow, DWC, drip, NFT), thanks to their inert nature, neutral pH and excellent drainage/ aeration properties.

Can I use them for soil or coco grows?
Absolutely. They can be used as a standalone inert medium, or mixed with coco/soil to improve drainage and aeration, or as a drainage layer under pots.

Do they affect nutrient solution stability or pH levels?
No, because they’re made from low-salt clay and are pH neutral, they won’t interfere with nutrient chemistry, making them safe for delicate hydro setups.

Are the pebbles reusable?
Yes, they’re inorganic, fungus-free and non-degrading, meaning you can rinse, sterilise and reuse them across many grow cycles.

Do the pebbles hold water / provide moisture retention?
Clay pebbles have some internal porosity that retains moisture while supporting drainage, but because of high drainage and aeration, they’re best used with regular nutrient/water cycling, typical for hydro or drip systems.

If you want a clean, stable and flexible medium for hydroponic, coco or soil-based cultivation, whether you’re a beginner or experienced grower, Canna Aqua Pebbles 50 L offer excellent aeration, root support and drainage. Their inert, pH-neutral nature ensures consistent nutrient uptake. Durable and reusable, they’re a cost-effective long-term investment that lays a solid foundation for healthy roots and high yields.
