🌱 Optimal root oxygenation
The irregular shape of Euro Pebbles creates micro-air pockets around the roots. Your plants build a dense, healthy root system that absorbs nutrients quickly — a key advantage in indoor growing under LED horticultural lighting.
💧 Anti-stagnation drainage
Placed at the bottom of pots or in hydro baskets, these clay balls prevent water from sitting around the roots. You avoid root rot, fungal diseases and water-stress shocks that slow growth and flowering.
♻️ Reusable & cost-effective
Inert and stable, Plagron clay rinses clean and reuses across multiple cycles. A smart long-term investment for regular growers — just rinse with clean water between crops to restore a clean, high-performing substrate.
Should I rinse the clay balls before use?
Yes, rinsing with clean water before first use is strongly recommended. It removes residual clay dust that could clog a hydroponic system or cloud your nutrient solution. For NFT or DWC hydro, rinse thoroughly until the water runs clear.
How many 10L bags do I need for a pot or hydro setup?For drainage at the bottom of 11-25 L pots: 1 bag covers 2 to 3 pots. For full hydro in Air-Pots or net cups, plan around 1 bag per 10 L pot. In NFT/DWC, size by basket volume (typically 0.5 to 1 L of pebbles per plant).
