Plants need oxygen to survive, which they receive from the soil through their roots. However, in a hydroponic environment, the soil is missing. That’s why water aeration is fundamental for plants in hydroponic gardening. To cultivate these plants, an ideal environment is formed in hydroponic reservoirs by setting up an air pump attached with air stone that diffuses the air into the roots of the plants and increases oxygen levels so that plants may thrive and flourish. In addition, the roots that are dipped in a nutrient solution require oxygen also entirely to absorb the missing nutrients and thrive.
Air stones with the help of air pumps form fine bubbles necessary to maintain a proper pH level, reduce carbon dioxide, and increase oxygen in hydroponics. Air stones protect your hydroponic garden from dying. One of the hydroponic gardening methods includes Deep Water Culture (DWC) that requires air stones as a crucial part of its procedure. Without air stones, the DWC system can’t be set up as the plants are grown through this method require oxygen the most, which they can acquire only from air stones.
Some air stones produce the larger size of bubbles, while some form tiny bubbles in abundance. Depending on what type of air stone you require, you can look through the different options available in the market. However, to make this task a bit easier for you, we have curated the four best air stones for deep water culture.

Jetting Volume: 28 L/min
Review:
I have a 20-gallon deep water culture tub for which I bought Pawfly’s air stone. This air stone is perfect in every sense. It provides a jetting volume of 28 L/min and superb aeration for hydroponics.
I use this air stone with a 20W air pump that provides ample energy to produce bubbles and circulate oxygen throughout the tank.
It’s an eco-friendly product made of high-quality carborundum material, which is toxic-free and washable. It weighs 3 lbs and doesn’t float inside the tub. Instead, the 3-suction cups allow the air stone to stabilize and remain fixed at the bottom. It produces 300 to 500-micron bubbles that are tiny but more than sufficient to fulfill the oxygen needed in the deep water culture system.
Overall, I am thrilled with this purchase because the air stone works too well. Furthermore, the cleaning and maintenance are very convenient. It only takes a brush to clean it, and that too after many months in case of clogging.
This air stone’s size and jetting volume are perfect for my hydroponics, and I love how it oxygenates the whole tub with ease without making me worry about my plants dying.
