3-Membrane Humidifier Float designed to stabilize the position of the ultrasonic module and generate constant cool mist in indoor cultivation. Compact format of 16 × 16 cm, ideal for open tanks, propagators, and cheap indoor grow cabinets.

The 3-Membrane Humidifier Float acts as a floating platform that keeps the ultrasonic capsule at the correct depth, optimizing mist production without adding heat to the environment.
The ultrasound technology operates above 20,000 Hz, vibrating the water and transforming it into microdroplets that efficiently raise relative humidity. This float works in buckets, containers, or open tanks and allows for quick refilling, as well as reducing splashes and breakdowns due to improper working height.
The 3-membrane configuration delivers a balanced flow for rooting zones, growth, and medium-sized rooms. To extend the lifespan of the set, it is recommended to use distilled, osmosis, or low mineralization water, minimizing scale buildup on the discs.
Many humidifiers include a water shortage cut-off; the float helps maintain a stable level for safe operation. As a general reference in 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 stretch until harvest 30–40%.
This component integrates with humidity controllers, hygrometers, and intake fans and is part of the cannabis cultivation accessories ecosystem available at a Grow Shop in Spain.
In indoor cultivation, the stability of relative humidity impacts transpiration, gas exchange, and VPD. A 3-Membrane Humidifier Float keeps the tablet at the optimal height and provides continuous mist, reducing RH peaks and valleys and improving canopy comfort.
Lightweight, stable accessory with a 16 × 16 cm format, perfect for use with irrigation tanks, buckets, and propagation trays. Ideal complement for RH controllers, timers, and air injection, both in domestic spaces and professional installations with cheap indoor grow tents.
Recommended for use in open tanks that feed 3-membrane humidifiers. The 3-Membrane Humidifier Float maintains alignment and height, improves nebulization efficiency, and helps achieve demanding humidity ranges in propagation, vigorous growth, and controlled flowering.

A great ally when RH drops due to air conditioning, lighting, or high air renewal rate.
To improve humidity in medium-sized rooms without adding heat, the 3-Membrane Humidifier Float provides stability, buoyancy, and easy maintenance. Integrated with ventilation, extraction, and controllers, it helps maintain indicative RH ranges (cuttings ~90%, growth 60–70%, mid-flowering 50–60%, final stretch 30–40%) and supports strong and uniform crops.
A practical solution to increase humidity with precision and safety. The 3-Membrane Humidifier Float offers a stable base for ultrasonic nebulization, optimizes cold mist creation, and simplifies daily maintenance.
