What is the Best Airstones for Your DWC?
As a part of the hydroponic method, the deep water culture or DWC in short sure does require a nutrient solution to ensure that the plants are growing at a good rate and in a healthy way.
The entire project needs a sufficient amount of oxygen while keeping the Carbon dioxide level at a minimum.
That is where air stones step in as they are necessary tools to carry out just the task of aeration. Before selecting an air stone, you need to consider some factors. Let us guide you through these factors to choose the best airstone for DWC.
Airstone VS Air Diffusers
Also going by the name aquarium bubbler, air stones are aquarium furniture that is needed to pump bubbles and diffuse air into the tank. This ultimately reduces the CO2 level in the water and fills it up with sufficient oxygen.
On the other hand, air diffusers are simply air circulator or air distribution subsystems. They are responsible to distribute and regulate airflow in an aquarium or hydroponics.
Both of these components are essential for a hydroponics system and are required to be paired up with an air pump. The airstone maintains oxygen level and aeration while the air diffuser maintains airflow.
What Size Air Stone Do You Need?
Although there are plenty of sizes available for air stones, picking one up entirely depends on the size of your hydroponic garden. The size directly impacts the effectivity of your air stone as the perfect one will aerate your hydroponics garden more effectively.
A simple rule of thumb is that pick an air stone that generates at least 500-600cc of air per minute to the nutrient reservoir. The cc count is just the same as the ml count per minute. Don’t stress over this as you will find the cheapest ones providing greater than this number.
How Much Airstones Does DWC need?
To ensure optimal growth of your plant, professionals recommend that you need enough air stones that can at least generate about 1 Liter per minute(LPM) through aeration and airflow for each gallon of water.
Suppose your hydroponic garden has about 5-gallon of water. It would require about 5 LPM of air stones to ensure smooth aeration. Subsequently, for 10- gallons of water USA 10 LPM airstones.
Type of Airstones for Hydroponics and Aquariums
Air stones come in three shapes and sizes. Eco plus, round disc, and micro pour. Each of these air stones has a slightly different purpose and functionalities.
- Eco Plus: Specifically designed for gardening, these air diffusers are reliable and operates quietly without producing much sound. These are quite common air stones among commercial gardeners.
- Round Disc: These disc-shaped air stones generate small bubbles that aerate aquarium, fish tank, and hydroponics. The small generated bubbles circulate nutrients inside the hydroponic to promote better health for your plants.
- Micro Pour: These air stones create the smallest of the bubbles compared to the other two types of air stones. This enables the air stone to increase its oxygen circulation ration for a surface area. Unlike other air stones that might break or suffer clog, micropores will never suffer such defects and perform effectively.

Why is Air Stone Necessary in DWC Hydroponic Gardening?

This is why air stones are necessary for aeration in hydroponics. They create small oxygen-rich bubbles that dissolve in the water and spread in the entire system. The air pump helps to push the oxygen bubbles in the system so that the plants receive enough nutrients from it.
How do the Hydroponic Air stone Work?
Paired with air pumps, the air stones generate a large number of small bubbles. The air pumps inject air through the stones and the stones give out bubbles filled with oxygen. These oxygen reach bubbles then diffuses in the water and give necessary nutrients to the plants inside of the hydroponics.
