Mist Maker Ultrasonic Humidifier for Grow Rooms

Serious Humidity Output From Any Bucket or Tank

The Mist Maker raises relative humidity by turning water into cold vapour using ultrasonic vibration, with no heater and no tank of its own to limit you. It sits in whatever vessel you already have, from a builder's bucket to a full reservoir, so it suits rooms a domestic humidifier cannot keep up with. Output scales with disc count, from 1200 ml/h up to 5300 ml/h. A float is essential, as the ceramic discs only work at the correct depth.

Key Benefits

• High output: up to 5300 ml per hour from the 12 disc model, enough for a large room
• Scale to the space: 3, 5 and 12 disc versions let you match vapour rate to room volume
• Unlimited reservoir: drop it in any bucket or tank, so capacity is whatever you can fill
• Cool vapour: adds humidity without adding heat to the room
• Runs unattended with a float: fill the tank to the top and the float keeps the discs at the right level until the water is gone

Struggling to Hold Humidity in a Big Room?

Strong extraction strips moisture faster than a small plug-in humidifier can replace it, so RH sits low all day and growth crawls. Dry air stresses young plants, drags out rooting and makes transplant shock worse. A disc mist maker with a big vessel behind it holds humidity properly and keeps going overnight.

How to Use

Place the unit in a bucket or tank of tap water with the water level just above the ceramic plate. Fit a Mist Maker Float, fill the tank right up and the unit will float at the correct depth until the water runs out. Point a circulation fan at the mist so it disperses evenly rather than settling as damp on the floor, and pair it with a humidity controller to hold your target RH.
