PVC Disc Air Stone, 10cm and 11.5cm, for DWC, Hydroponics and Aquaponics

💧 Keep Your Roots Happy with Dense, Fine Bubble Aeration

If your plants are sitting in a deep water culture bucket or nutrient reservoir, they need a steady, reliable flow of oxygen to their roots. This PVC disc air stone connects to any standard air pump via airline tubing and gets straight to work, pushing a wide, dense column of fine bubbles up through your water from the very bottom of the reservoir.

Available in two sizes: 10cm and 11.5cm, so you can match it to your setup whether you're running a compact single bucket or a larger reservoir system.

🌿 Why Growers Choose the Disc Shape

Stick air stones push bubbles in a narrow line. This disc throws them in a wide, flat spread across the base of your reservoir, giving your roots far more contact with oxygenated water. More oxygen at the roots means faster, healthier growth and a happier plant overall.

🛡️ Built to Last in Wet Environments

The outer PVC bumper ring protects the stone from chipping or cracking if it gets knocked around during water changes or maintenance. It's a small detail that makes a real difference over time, especially in setups where you're regularly lifting and moving things around.

⚓ Stays Put at the Bottom

One of the most common frustrations with air stones is that they float or flip over, sending bubbles sideways instead of upward. The flat, heavy profile of this disc means it sinks straight to the bottom and stays there, flat and stable, doing exactly what it's supposed to do.

✅ What's Great About It
