75 mm Diffuser Ring

Buy 75mm Diffuser Ring for indoor growing irrigation

The 75mm Diffuser Ring is a compact solution for aerating fertilizer tanks and maintaining the nutrient mix in balance. The fine-grained porous stone generates uniform microbubbles that travel through the water column, promoting gentle circulation and preventing dead zones and sludge buildup.

The circular design distributes the flow in 360°, helps keep additives in suspension and reduces odors associated with stagnant water.

Thanks to the standard silicone tubing connection, installation with a domestic or professional air pump is quick and reliable.

The 75 mm diameter offers a balanced emitting surface for small and medium-sized tanks, ideal when seeking efficiency without oversizing equipment.

Compatible with coco coir, peat, expanded clay peat and rockwool, this ring enhances the performance of the irrigation system in grow tents and tables, stabilizing EC and pH and facilitating constant nutrient absorption by the roots.

Indoor Growing 75mm Diffuser Ring.

In indoor growing setups with drip irrigation, recirculation, or pressurized tanks, an adequate dissolved oxygen level makes all the difference. The 75 mm ring multiplies gas exchange and generates a film of fine microbubbles that improves the root environment, maintains a homogeneous nutrient solution, and promotes balanced growth during both the vegetative and flowering phases. The result is uniform hydration that supports vigor, color, and leaf density.

What is the purpose of the 75mm Diffuser Ring?

• Constant oxygenation : microbubbles that raise DO and reduce anaerobic conditions.
• Homogeneous mixture : perimeter circulation that keeps nutrients and additives in suspension.
• Less sediment : helps reduce sludge, biofilm and bad odors in tanks and lines.
• Energy efficiency : compact diameter that works very well with medium flow pumps.
• Versatility : suitable for DWC/RDWC systems, drip irrigation and auxiliary reservoirs of the irrigation system .

Accessories for indoor cultivation irrigation: 75 mm Diffuser Ring.

For optimal performance, it is advisable to integrate these irrigation accessories :

• Air pump sized to the volume of the tank (reference: 3–6 L/min per diffuser).
• Silicone tubing compatible with standard ring spigot and fittings.
• Non-return valve between pump and diffuser to prevent water backflow.
• Tank lid and filter on the main line to minimize the entry of dust and particles.
• Water temperature control between 18–22 °C for chemical and biological stability.

With this set, the 75 mm Diffuser Ring maintains continuous oxygenation, making it easier to water indoor crops with uniformity and predictability.

How do I use the 75mm Diffuser Ring?

1. Rinse the ring under the tap to remove factory dust.
2. Connect the silicone tubing to the diffuser and the air pump , inserting a non-return valve into the line.
3. Place the ring at the bottom of the tank, preferably centered; secure with a weight or suitable suction cup if necessary.
4. Turn on the pump and check for even distribution of bubbling around the entire 75 mm perimeter.
5. Operate continuously or in cycles (e.g., 15–20 minutes every hour) depending on demand, temperature, and tank size.
6. For maintenance, periodically soak in warm water with a specific cleaner or diluted peroxide; rinse and reinstall.

Practical tip: Keep the reservoir level above the diffuser and check the flow rate weekly to preserve aeration efficiency during periods of high feeding.
