The 50mm Diffuser Ball is a spherical porous stone for oxygenating fertigation reservoirs in indoor growing . It generates fine, homogeneous microbubbles, connects to an air pump via silicone tubing , and helps to water indoor plants uniformly, preventing dead zones and sludge.

The 50mm Diffuser Ball is designed to increase dissolved oxygen (DO) in the water and maintain a gentle, constant movement of the nutrient solution. Its fine-grained, porous mineral body emits a curtain of microbubbles that travels through the water column, improving fertilizer mixing and reducing odors associated with stagnation.
The 50 mm diameter offers a larger emitting surface than more compact formats, with low back pressure to work with domestic or professional pumps without oversizing the equipment.
The standard silicone tubing connection facilitates immediate integration into any irrigation system with drip, recirculation, DWC/RDWC or auxiliary tanks.
A stable aeration pattern promotes white and active roots, stabilizes EC and pH, and helps to keep nutrients in suspension in substrates such as coco coir, peat, expanded clay, and rockwool.
To preserve long-term performance, it is advisable to avoid direct exposure to intense light, not exceed 40°C in the water, and apply simple cleaning routines that restore the active pore of the stone.
The result is a more homogeneous delivery of water and nutrients, key for predictable and productive cycles within indoor grow tents and tables.
In intensive irrigation systems, an adequate level of dissolved oxygen makes all the difference. The 50 mm Diffuser Ball distributes air 360°, promoting perimeter circulation in the reservoir and limiting anaerobic zones that harm the rhizosphere. This fine aeration keeps fertilizers and additives uniformly mixed, preventing stratification and supporting consistent absorption with each irrigation. The results are noticeable in vegetative vigor, color, response to nutrient uptake, and overall water stability in the irrigation system .
For a reliable set of irrigation accessories, it is recommended to combine:
With this kit, the 50mm Diffuser Ball maintains constant oxygenation, facilitating regular and predictable watering of indoor crops , minimizing problems caused by sedimentation or sudden changes in EC and pH.
Practical tip: Keep the water level stable above the stone to avoid irregular bubbling and check the flow rate weekly, especially during periods of high feeding.
