Plagron Euro Pebbles - Hydroponic Substrate with High Water Retention, pH Neutral, Low Density

Euro Pebbles is an inert hydroponic substrate consisting of expanded clay pebbles designed for excellent drainage and root aeration in recirculating hydroponic systems. The 8–16mm granules provide large spaces between particles, facilitating air and liquid flow, ideal for growers who want total control over the root environment.

• Granule size: 8–16 mm
• Material: expanded ceramic balls, 100% inert, salt-free, fired in an open oven for irregular shape
• Packaging: 10 L bag (approx. 4–5 kg)
• Purity and preparation: wash product before packaging; there may be dust during transport, it is recommended to rinse before use
• Compatibility and Use: suitable for hydroponics in recirculating systems; can be mixed with peat or coir for additional drainage
• Plot parameters: pH EN13037 (H2O) between 6.8 and 8.3; EC about 0.2–0.9 mS/cm (ratio 1:1.5)
• Reuse: can be used for years, with proper sanitation and removal of plant residues between cycles

Euro Pebbles provide a clean, safe environment for closed circuit installations and the granules ensure rapid drainage and good oxygenation of the roots, reducing the risk of over-watering. It can be used directly as a single substrate or mixed into mixtures for improved drainage. For best results, start fertilizing from day one with a nutrient solution suitable for hydroponics and clean the material well before planting.
