120 mm Diffuser Plate. in disc format to increase the oxygenation of water in reservoirs and mixing tanks. Direct connection to air pump via silicone tube and uniform microbubble curtain that stabilizes pH, EC and promotes active roots in indoor cultivation. Available at Hydroponics Blanes, online grow shop with discreet shipping and advice from a trusted Grow Shop.

The 120 mm Diffuser Plate is a circular diffusion stone that distributes the air flow through thousands of fine pores to increase the dissolved oxygen (DO) in the nutrient solution.
The 120 mm diameter generates a wide mantle of fine bubbles that gently moves the water, reduces dead zones at the bottom of the tank, and limits the appearance of biofilm and odors.
In 40–200 L tanks, the disc promotes homogeneous mixes between irrigations, improves nutrient availability, and helps keep lines and drippers in better condition.
The standard barb accepts silicone tubing used in technical horticulture, so integration with diaphragm or piston pumps is immediate.
Combined with irrigation accessories —check valve, line filters, flowmeter—, the plate stabilizes the hydraulic circuit and provides repeatability to the irrigation system during each indoor crop watering session.
In controlled environments, good tank aeration makes the difference. The 120 mm Diffuser Plate provides a 360° microbubble curtain, ideal for flood tables, mixing tanks, and recirculating systems (DWC/RDWC). The water remains in gentle motion, stratification decreases, and each irrigation delivers a more stable solution to all pots or channels. The result is reflected in white roots, cleaner drainage, and uniform growth throughout the cycle.
For best performance, it is advisable to use with an air pump sized to the tank volume (L/min suitable for the plate diameter), food-grade silicone tube, check valve to prevent water from returning to the pump, and suction cups or ballast to keep the disc stable 5–10 cm from the bottom. In advanced installations, a dissolved oxygen meter allows precise flow adjustment, and opaque lids reduce light entry. All these irrigation accessories are available at Hydroponics Blanes, with a complete catalog in the online grow shop and discreet shipping.
Technical tip: use two plates in parallel in large tanks to cover opposite areas and alternate cleaning, maintaining a constant bubbling pattern throughout the week.
Economic investment with a direct impact on root vigor and water stability. At Hydroponics Blanes there are packs with air pump, tubing and valves, as well as options to integrate the disc into an automated irrigation system.
