20 cm Air Stone

20 cm Diffuser Stone Price.

The 20 cm Diffuser Stone is an aeration component with uniform pores that distributes the flow in thousands of points, increasing the gas-liquid exchange surface and the dissolved oxygen (DO) of the nutrient solution.

This increase in DO helps maintain white and vigorous roots, limits the appearance of biofilm, and reduces odors in tanks. The linear format of 20 cm is optimal for medium and large tanks, flood tables, and recirculating systems (DWC/RDWC), promoting the homogenization of pH and EC between irrigations.

The connection accepts standard silicone tubing, so integration with diaphragm or piston pumps is immediate. Combined with irrigation accessories such as a check valve and inline filters, this diffuser stabilizes the hydraulic circuit and brings repeatability to the indoor crop watering process.

Better oxygenated water increases nutrient availability, prevents dead zones at the bottom of the tank, and keeps particles in suspension for a more uniform mix before dosing.

All this translates into less maintenance of the irrigation system, cleaner lines, and more uniform batch development.

Indoor growing 20 cm Diffuser Stone.

In indoor growing, oxygenation makes the difference between a stable system and one with issues. The 20 cm Diffuser Stone generates a layer of microbubbles that improves root respiration, supports beneficial microbial activity, and helps prevent stratification in 60–250 L tanks. Placed in areas with less circulation, it breaks up pockets of stagnant water and ensures that each irrigation delivers the same mix to all plants.

What is the 20 cm Diffuser Stone for?

• Oxygenate the water to raise DO and promote nutrient absorption.
• Homogenize the nutrient solution, stabilizing pH and EC between irrigations.
• Reduce biofilm and odors by avoiding low-oxygen areas in the tank.
• Mitigate thermal stress of the root system during warm periods.
• Support cleaning by keeping fine particles in suspension before filtering.

Irrigation accessories for indoor growing 20 cm Diffuser Stone.

Performance improves with an air pump sized to the tank volume (L/min according to the length of the stone), food-grade silicone tubing, check valve to prevent water backflow to the pump, and weight or suction cups for stable fixation. In advanced setups, it is advisable to add a dissolved oxygen meter to adjust flows precisely and opaque lids to limit light in the tank. This entire set of irrigation accessories is available at Hydroponics Blanes, with technical support, discreet shipping, and a complete catalog in the online grow shop.

How is the 20 cm Diffuser Stone used?

1. Cut the silicone tubing to size and insert a check valve between the pump and diffuser.
2. Rinse the 20 cm Diffuser Stone to remove pore dust and connect to the tubing.
3. Submerge in the tank 5–10 cm from the bottom; secure with weight or suction cup.
4. Turn on the air pump and adjust flow until you see fine, uniform microbubbles.
5. Operate continuously or in intervals; clean every 2–4 weeks with gentle brushing or a bath in diluted food-grade peroxide.

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