£0.75

Compact 50mm golf ball air stone for adding a steady stream of bubbles and extra aeration to hydroponic nutrient solutions.

The 50mm Golf Ball Air Stone is a simple and effective way to aerate nutrient solutions and water reservoirs. Connect it to a suitable air pump using 4mm airline and the porous stone disperses the incoming air as bubbles throughout the solution.

Increasing aeration helps keep nutrient solution moving and supplies additional oxygen to the water around the root zone. Its compact golf ball shape makes this a useful choice for individual reservoirs, DWC buckets, bubbler systems and other hydroponic setups where space is limited.

For larger growing systems, several air stones can be operated from a suitably sized air pump using an airline manifold, allowing aeration to be distributed across multiple pots or reservoirs.

Why use a 50mm Golf Ball Air Stone?

  • Improves nutrient solution aeration – disperses air through the water to increase oxygenation.
  • 50mm golf ball design – compact enough for individual reservoirs, buckets and hydroponic systems.
  • 4mm airline connection – connects to compatible 4mm airline and a suitable air pump.
  • Porous diffuser – breaks the incoming airflow into bubbles rather than releasing it from a single open airline.
  • Ideal for hydroponics – suitable for nutrient tanks, reservoirs, DWC and bubbler systems.
  • Easy to expand – use several air stones with a suitable manifold and air pump for multi-pot installations.

What is a golf ball air stone used for?

A golf ball air stone is submerged in water or nutrient solution and connected to an external air pump. Air passes through the porous body of the stone and is dispersed into the surrounding solution as bubbles.

In hydroponic growing systems, air stones are commonly used in nutrient reservoirs and DWC systems to increase aeration around the root zone. They can also help keep the solution moving rather than allowing it to remain completely still.

How to use the 50mm Golf Ball Air Stone

Connect a length of compatible 4mm airline to the air stone inlet, then connect the other end to a suitable air pump or air manifold. Place the air stone below the surface of the water or nutrient solution and switch on the air pump.

Positioning the air stone towards the bottom of the reservoir allows the bubbles to travel through more of the solution before reaching the surface, helping circulate and aerate the surrounding water.

When running several air stones from one pump, make sure the pump provides sufficient airflow for the complete setup. A manifold can be used to divide the main air supply between individual 4mm airline runs.

50mm Golf Ball Air Stone FAQs

What does a golf ball air stone do?

An air stone takes air supplied by an external pump and disperses it as bubbles through water or nutrient solution, helping increase aeration and circulation.

What size is this air stone?

The golf ball air stone measures 50mm in diameter.

What size airline does the 50mm air stone use?

It has a 4mm connection for compatible airline.

Do I need an air pump to use this air stone?

Yes. The air stone needs to be connected by airline to a suitable external air pump or compressor to produce bubbles.

Can I use this air stone in a hydroponic nutrient reservoir?

Yes. The 50mm golf ball air stone is well suited to aerating nutrient solution in hydroponic reservoirs and tanks.

Is a 50mm golf ball air stone suitable for DWC?

Yes. Golf ball air stones are commonly used in deep water culture and bubbler systems to provide continuous aeration within the nutrient solution.

Where should I position the air stone?

Place the air stone below the surface of the solution, preferably towards the bottom of the reservoir or bucket so the bubbles can rise through the water.

Can I run several air stones from one air pump?

Yes. A suitably sized air pump can supply multiple air stones. An airline manifold can be used to split the main air supply into several individual airline feeds.

Does the air stone come with airline?

No. The air stone is supplied separately, so compatible 4mm airline and a suitable air pump are required to create a working aeration setup.
