Description
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. The mist is a very fine, micron-sized droplet that evaporates quickly into the air, the unit runs quietly from a standard UK socket through its own transformer, and its coated discs are rated for up to 2,000 working hours.
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
- Low-water cut-out: the unit switches itself off when the water drops too low, so the discs never run dry
- Long-life discs: coated ceramic discs rated for up to 2,000 working hours
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.
Choosing 3, 5 or 12 Discs
Output rises with the number of discs. The 3 disc (1200 ml/h) suits a grow tent, propagation area or small room, and the 5 disc (1600 ml/h) gives more headroom where extraction is strong. The 12 disc (5300 ml/h) is built for large grow rooms and dedicated veg or cutting rooms; it runs on a 36 V AC low-voltage supply from a 300 VA transformer rated IP44. Each size has its own matching float.
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. The manufacturer recommends ordinary tap water so the low-water sensor reads reliably; wipe scale off the discs from time to time to keep output up, and keep the transformer dry and off the floor.

Frequently Asked Questions
Do I need a float?
Yes. The discs only produce their rated output at the right depth below the surface, and the float holds them there as the water level drops. Use the float made for your disc count - 3, 5 or 12 disc.
Can I run it from a humidity controller?
Yes. Plug the mist maker's transformer into a plug-in humidistat and set your target RH; the controller switches the unit on and off to hold it, which is far steadier than running it on a timer.
What water should I use?
Ordinary tap water - the manufacturer recommends it so the low-water sensor works properly. In hard-water areas, clean the scale off the discs regularly to keep the mist output up.
Will the mist wet my plants?
The droplets are very fine and evaporate quickly, but stand the bucket or tank away from the canopy and run a circulation fan across it so the mist spreads through the room instead of settling on leaves or the floor.
