30 cm Air Stone

30 cm Diffuser Stone for irrigation water

The 30 cm Diffuser Stone offers a large porous surface that distributes the flow in thousands of points, increasing the gas-liquid exchange area and, therefore, the dissolved oxygen (DO) of the nutrient solution.

This constant supply of oxygen keeps the water gently moving, limits dead zones, stabilizes pH and EC between irrigations, and promotes white and active roots.

The linear format of 30 cm is ideal for medium and large tanks (80–300 L), flood tables, and recirculating systems like DWC/RDWC, where mixture homogeneity and oxygenation make the difference.

The spigot fits standard silicone tubing, compatible with diaphragm or piston pumps commonly used in technical horticulture.

Integrated with filters, valves, and flow meters, this stone helps keep the circuit clean, reduces odors, and facilitates uniform dosing throughout the irrigation system.

In demanding rooms, it provides batch-to-batch repeatability and reduces maintenance times, as the mixture remains ready to water indoor crops precisely at any time.

Indoor growing 30 cm Diffuser Stone

In indoor growing, proper oxygenation is key to root health and nutrient absorption. The 30 cm Diffuser Stone creates a layer of microbubbles that renews the oxygen in the tank, prevents stratification, and helps each irrigation deliver a stable solution to all pots or channels. The result: uniform growth, cleaner drainage, and fewer incidents from algae or biofilms.

What is the 30 cm Diffuser Stone for?

• Oxygenate the water to raise DO and improve nutrient uptake.
• Homogenize the solution avoiding settling and variations in pH/EC.
• Reduce biofilm and odors by minimizing low-oxygen zones in the tank.
• Mitigate thermal stress of the root system during warm periods.
• Support line cleaning by keeping fines in suspension before filtering.

Accessories for indoor irrigation growing 30 cm Diffuser Stone

For an efficient setup, it is advisable to combine with an air pump sized to the tank volume (adequate L/min for 30 cm), food-grade silicone tube, check valve to prevent water backflow, and weight or suction cups for stable fixing. In advanced setups, a dissolved oxygen meter allows precise flow adjustment, while opaque lids reduce light entry. The entire ecosystem of irrigation accessories is available at Hydroponics Blanes —online grow shop with discreet shipping— to integrate this stone into a robust irrigation system.

How to use the 30 cm Diffuser Stone?

1. Cut the silicone tube to size and insert a check valve between pump and diffuser.
2. Rinse the 30 cm Diffuser Stone to remove dust from the pores and connect to the tube with a firm fit.
3. Submerge in the tank 5–10 cm from the bottom; fix with weight or suction cups to prevent movement.
4. Turn on the air pump and adjust flow until you see fine, uniform microbubbles.
5. Operate continuously or intermittently; clean every 2–4 weeks with gentle brushing or a bath in diluted food-grade peroxide.

Technical tip: in tanks >150 L, use two stones in parallel and alternate cleaning to maintain a constant bubbling pattern throughout the week.
