Boyu – Golf Ball Airstone
- 50mm ball airstone will fit almost any size reservoir
- Porous stone creates many small bubbles
- Mixes and oxygenates your nutrient solution
- Oxygenated nutrient solution improves root-health and turbo-charges plant growth
- Air pump and air line available separately
- Various amounts available
The 50mm ball airstone is a 50mm diameter ball of porous stone. An inlet nodule is located on it to allow the airstone to be connected to an air pump via a length of air line. When connected to an air pump, the air will exit the airstone through the many pores in the stone. When the airstone is submerged in water or a nutrient solution, the effect is that many small bubbles are produced and released from the surface of the stone. The bubbles create movement in the water or nutrient solution keeping it well mixed. The movement at the surface also greatly increases the amount of oxygen being dissolved into it. Dissolved oxygen discourages anaerobic microbes which can cause root diseases and feeds oxygen to the friendly aerobic microbes. An airstone helps to keep your plant’s roots healthy while also providing oxygen for the roots to absorb. Adding an airstone to your reservoir really does increase the speed of your plant’s growth and creates a healthier root-system. An airstone is very highly recommended for all hydroponic systems.
Connect the airstone to your air pump using 4mm pvc or rubber air line. If the air line is difficult to fit over the inlet, dipping the end in warm water should make job much easier. Always make sure that your air pump is at a higher level than the surface of the water in your reservoir to prevent water siphoning back into the air pump. Lower the airstone down to the bottom of your reservoir and switch your air pump on. The porous stone used in airstones is brittle and should be handled carefully to prevent breakages. Every so often, gently clean the surface of the airstone to maintain the air-flow and bubble production. Airstones do degrade with use and will become clogged and more brittle over time. Try to make sure you replace them regularly.

Did you know that you can drown your plants? It’s true. And it’s not the same as just overwatering a potted plant. When you overwater a plant, you risk issues like mould and root rot. When you drown your plant, it quite literally lacks oxygen, as a drowning human would.
That’s where air stones come into play for your hydroponic growing strategy. This article gives you the basics on what air stones are and why you need them. You’ll also find out precisely what role oxygen plays in hydroponics and plant health.
Here’s why your reservoir tank needs air stones.
What are air stones used for?
You may already be familiar with air stones if you’ve used them in fish tanks.
Air stones create tiny bubbles of oxygen in your hydroponic tank when the air is forced through the stone. The bubbles make the dissolved oxygen disperse more widely throughout your system. Typically, the oxygen bubbles are pushed through the system with an air pump, which we will discuss more in a later article. The stones themselves are submerged in the water or nutrient solution inside your reservoir.
Note that the stones themselves do not actually generate oxygen. They act as a mechanism to disperse the oxygen.
What is the role of oxygen in hydroponics?
When plants grow outdoors in soil, natural processes allow oxygen to penetrate the earth and get to the plants’ roots. For example, worms churn the dirt, which disperses oxygen, making it more accessible to the roots.
But why do plants need oxygen at the roots? The oxygen actually assists the process of nutrient uptake. When more oxygen is present, plants can better absorb minerals and even water. That means the air stones can make your nutrient solution more efficient. Without enough oxygen, plants are likely not to grow to their full potential, in part because they aren’t taking nutrients ineffectively.
In addition to aiding nutrient uptake, increased oxygen circulation around the roots also helps to prevent harmful pathogens from taking hold and making plants sick. The lack of pathogen protection from insufficient oxygen is directly related to plant nutrition. When there’s not enough oxygen, the plant doesn’t get enough nutrients, and when it doesn’t get enough nutrients, it produces stress hormones that make it less able to fight off everpresent bacteria.
Choosing an air stone
Air stones come in a few different sizes and shapes. It’s not hard to select one, though. Use smaller stones for smaller setups and larger stones for larger setups. As for the shape, pick one that roughly matches the shape of your tank. The most common shapes for these oxygen dispersers are rectangle or cylinder.
You can try a few different air stones and experiment with which shape and size will work best for your nutrient tank.
Air stones are not expensive at all. They’re a tiny investment that can make a big difference in the health of your plants. So come in and check out the airstone options at Gone To Pot Hydroponics.
“These larger units deliver larger bubbles over a bigger area, than the 25mm ones supplied with the pump, the pump is quieter as it is not working as hard. I consider them very good value for money.”
“ Arrived early and are a great size, does what it says in the description and also does wonderful in my 100 gallon intex pool for my fish, i would highly recommend to people who are looking for a cheap but good air stone for a large aquarium or small pond.”
“these are ideal for the pond, think they would be too big for an aquarium. Good flow of bubbles. happy with my purchase“
