5 Membrane Humidifier Float keeps the ultrasonic module at the exact height to generate stable cool mist in indoor cultivation. Compact format of 21 × 21 cm, immediate installation in open tanks, ideal for rooms and cheap indoor grow cabinets.

The 5-Membrane Humidifier Float acts as a floating platform that stabilizes the working level of the ultrasonic nebulizer, optimizing the conversion of water into microdroplets through vibration above 20,000 Hz.
The 5-membrane configuration offers a balanced mist flow for medium-sized rooms, propagators, and flowering areas that require homogeneous humidity without raising the ambient temperature.
The floating body facilitates quick refills in buckets, containers, or open tanks, reduces splashes, and prevents stoppages due to poor cartridge immersion. To extend the lifespan of the unit, it is recommended to use distilled water, osmosis water, or low mineralization water, minimizing lime scale build-up on the discs.
Many devices incorporate a safety cut-off for lack of water; the float helps maintain a stable level and continuous operation. Indicative humidity values 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%. Integrated with humidity controllers, air injection and extraction, this float stands out as one of the essential cannabis cultivation accessories you will find in a Grow Shop in Spain.
In indoor cultivation, keeping relative humidity within the target range stabilizes VPD, improves gas exchange, and reduces water stress. The 5-Membrane Humidifier Float ensures optimal module position to produce constant, fine mist, promoting a uniform microclimate throughout the canopy.
Robust and stable accessory, designed for irrigation tanks, buckets, and trays. Approximate dimensions 21 × 21 cm that provide buoyancy and support surface for the 5-membrane module. Compatible with RH controllers, hygrometers, and timers, both in domestic installations and in professional rooms and cheap indoor grow tents.
Recommended for use in open tanks that feed five-disc humidifiers. The 5-Membrane Humidifier Float maintains alignment and height, improves nebulization efficiency, and helps achieve demanding RH ranges in propagation, vigorous growth, and controlled flowering within a comprehensive environmental control plan.
