Flexible Air Diffuser 60 cm. provides constant oxygenation to reservoirs and indoor cultivation tanks, improving gas exchange in roots and water stability. Made of high-resistance silicone, in black color, it adapts to the contour of the reservoir for a homogeneous distribution of fine bubbles.

The Flexible Air Diffuser 60 cm. is a porous line of silicone that, connected to an air pump, generates a curtain of microbubbles along the entire section. The flexible structure allows you to form circles, semicircles, or perimeter lines inside the tank, creating areas of uniform oxygenation that help keep nutrients suspended and improve water temperature through slight convective movement.
By increasing dissolved oxygen, roots breathe better, biofilm formation is reduced, and parameters such as pH and EC are stabilized for longer.
With 60 cm in length and a black finish, it visually fits into opaque tanks and prevents reflections.
It features a standard connector for aquarium/hydroponic air hose and works with air pumps of usual flow in grow tents.
It is a direct accessory for support DWC systems, drip irrigation tanks, light recirculation, NFT, and fertilizer mixes between batches.
Within the Hydroponics Blanes online grow shop, a trusted Grow Shop with discreet shipping, it is offered alongside an ecosystem of irrigation accessories that boost the performance of any irrigation system.
In indoor growing environments, the Flexible Air Diffuser 60 cm. improves aeration of the nutrient tank, key to avoiding dead zones. The fine microbubble increases dissolved oxygen and facilitates ion uptake, resulting in white, vigorous roots with greater tolerance to thermal fluctuations. Placing it around the perimeter or forming a ring under the pump creates a gentle flow that minimizes sediment at the bottom and helps water indoor crops with a more homogeneous solution.
It is used to enrich the nutrient solution with oxygen, reduce stagnant odors, prevent the formation of surface layers, and keep nutrients in light motion. It is especially useful in 40–200 L tanks, auxiliary tanks, and vats used to prepare fertilizers before transfer. It also supports pulse irrigation strategies, stabilizing the mix between cycles and preventing salt stratification that compromises uniformity when watering indoor crops.
To maximize its potential, it is advisable to combine the Flexible Air Diffuser 60 cm. with:
All these irrigation accessories are available at Hydroponics Blanes, with technical advice and discreet shipping from the online grow shop.
1) Rinse the diffuser before first use.

3) Connect to air pump using hose and check valve.
4) Adjust flow until uniform microbubble is obtained along the entire length.
5) Keep running continuously when the solution remains in the tank for more than 24–48 h.
6) Perform periodic cleaning by immersing the diffuser in diluted peroxide or vinegar solution and rinsing with clean water.
