12 Membrane Humidifier Float designed to keep the ultrasonic unit stable and produce constant cool mist in indoor cultivation. Robust format for open tanks, approximate dimensions 28 × 28 cm, ideal for technical rooms and cheap indoor grow cabinets.

The 12 Membrane Humidifier Float works as a floating platform that positions the ultrasonic module at the optimal working depth, ensuring constant contact with the water and sustained performance.
Through vibration at frequencies above 20,000 Hz, the 12 membranes turn water into microdroplets that disperse as cool mist, raising relative humidity without adding heat to the environment.
This float is used with tanks, buckets, or open containers, allowing quick refilling, preventing unwanted splashes, and minimizing downtime due to poor module seating. The support surface provides stability for large fog flows in propagation, growth, or flowering rooms that require precise and homogeneous humidity.
To prolong the life of the ultrasonic assembly, it is recommended to use distilled, osmosis, or low mineralization water, reducing lime scale on the discs.
As a guideline for cannabis: cuttings ~90%, germination week 1 ~80%, start of growth week 2 70–80%, growth weeks 3–6 60–70%, start of flowering weeks 7–8 50–70%, flowering weeks 9–12 50–60%, final stage until harvest 30–40%.
This component naturally integrates with humidity controllers, timers, and intake fans, forming part of the cannabis cultivation accessories ecosystem available at a Grow Shop in Spain.
In indoor cultivation keeping humidity within the target range reduces water stress and promotes a balanced VPD. The 12 Membrane Humidifier Float stabilizes the water level and allows for powerful and constant mist production, ideal in large rooms, commercial propagators, and controlled drying areas.
Key accessory for high-capacity ultrasonic humidifiers. Dimensions 28 × 28 cm that provide buoyancy and stability to the assembly, perfect for integrating with RH controllers, hygrometers, and renewal ventilation. Common accessory in setups with cheap indoor grow tents and also in large professional rooms.
Recommended use in open tanks that feed 12 membrane humidifiers. The float keeps the module aligned, improves nebulization performance, and helps achieve demanding humidity ranges in propagation, vigorous growth, and controlled flowering, within the cannabis cultivation accessories package.
