ข้อเท็จจริงสำคัญ

• Inert, pH-neutral, and chemically stable — do not break down over time
• Excellent drainage prevents waterlogging; high porosity supports root oxygenation
• Reusable after sterilisation — wash, soak in diluted hydrogen peroxide, and reuse
• Used in net pots for NFT, DWC, Kratky, and media-bed systems
• Lightweight relative to soil or gravel — ideal for stacked or vertical systems
• Rinse thoroughly before first use to remove clay dust that can clog pumps
