Diffuser Stones – Air Diffuser to Oxygenate Water in Tanks and Cultivation Systems

Frequently asked questions

• What are air stones used for in growing?

  They help oxygenate the nutrient solution better, spreading the fresh air the pump generates throughout the reservoir. They also keep the nutrients mixed and prevent them from settling at the bottom. The result is more oxygenated water and plants that absorb what you give them better.

• Do I need an air pump to use them?

  Yes, the stone alone doesn't generate air: you need a pump to supply it. The pump connects to the stone via a hose through which the air travels until it's released into the reservoir. With most models you'll also need non-toxic silicone tubing.

• How exactly do they work?

  Air arrives from the pump in the form of bubbles, and the stone retains and filters it before releasing it into the water. This achieves finer, more evenly spread oxygenation, and purer water. That improves the substrate and makes it easier for the roots to absorb nutrients.

• Are there different air stone formats?

  Yes, they come in different shapes and sizes to better suit the type of water reservoir you have. Choose the one that fits the volume and geometry of your tank. In fact, no grow reservoir should really be without one.

• Are they fragile? How do I take care of them?

  Yes, you need to handle them carefully because they can break if they fall on the floor. To work properly, they need to stay clean and away from sunlight. They also shouldn't be exposed to temperatures above 40°C.

• What do I gain by oxygenating the irrigation reservoir?

  Well-oxygenated water provides the vital air that roots need and keeps the nutrients in suspension. Since they don't settle at the bottom, plants absorb them much more easily. It's a small, inexpensive piece with a big impact on your watering.
