Sonic Air Humidifier 23L

High-capacity humidity control to stop dry air stalling your grow

The Sonic Air Humidifier 23L from G.A.S is a high-output ultrasonic unit built for grow tents and grow rooms where extraction and lighting constantly pull moisture from the air. A large 23-litre reservoir and adjustable mist up to 1.44 litres per hour let you dial humidity in for propagation, veg or flower across hydroponics, coco or soil. Run it standalone or link an optional float valve for continuous top-up, and pair it with a humidity controller for hands-off climate control.

Key Benefits

• 23-litre reservoir for long run times between refills
• Adjustable mist up to 1.44 litres/hour for fine humidity control
• 110W power draw for efficient high-output operation
• Top-fill lid for quick, mess-free refilling
• Optional float-valve connection for automatic refill from a reservoir
• Controller compatible and mounted on wheels for easy positioning
• Automatic low-water shut-down to protect the unit

Is dry air holding back your clones and vegging plants?

Strong extraction and hot lighting quickly strip humidity from a grow space, and dry air slows vegetative growth, reduces nutrient uptake and stresses young plants and clones. The Sonic Air 23L stabilises humidity so plants keep healthy transpiration rates, supporting stronger roots and faster veg, while a smoother transition into flowering protects bud density and yield.

How to Use

1. Position the humidifier on a stable surface in the tent or room.
2. Fill through the top-fill lid using RO water to protect the internal components.
3. Adjust the output control to set the mist level for your target humidity.
4. For automated control, connect to a compatible humidity controller.
5. If using the optional float valve, connect a reservoir positioned higher than the unit so gravity feeds it.
6. Monitor humidity and adjust output as required; the unit shuts down automatically if water runs low.
