Dehumidifiers & Humidity

Control humidity levels precisely with our range of ultrasonic humidifiers from SonicAir, available in multiple sizes to suit small tents through to large commercial grow rooms. Maintaining correct humidity is critical for healthy plant growth and mould prevention throughout every stage of the grow cycle.

Why humidity control matters at every stage

Different growth stages need different humidity ranges — higher humidity supports strong vegetative growth and propagation, while lower humidity during flowering helps prevent mould and bud rot. Getting this wrong at the wrong stage is one of the most common causes of crop loss for home growers, making reliable humidity control genuinely important, not just a nice-to-have.

Choosing the right size humidifier

Our SonicAir range scales by tank capacity and output — the standard 10L unit suits smaller tents, the 23L model handles medium spaces with easier top-up via hose connection, and the Pro model (with direct water intake rather than a tank) is built for larger commercial grow rooms needing continuous high-volume output.

Ultrasonic vs other humidifier technology

Ultrasonic humidifiers use high-frequency vibration to create a fine water mist, offering quiet operation and precise, adjustable output — generally preferred in grow rooms over evaporative alternatives for their controllability and low noise.

FAQ

Should I use tap water or RO water in my humidifier?
Most manufacturers recommend RO (reverse osmosis) water where possible — using tap water can void warranty terms and lead to mineral buildup on the ultrasonic components over time.

How do I know what size humidifier I need?
Match the output (litres/hour) to your room size and target humidity — larger spaces or higher humidity targets need proportionally higher output capacity.

Can a humidifier run continuously without supervision?
Most models include automatic shut-down features to prevent damage if the tank runs dry, but regular monitoring is still recommended, especially with tank-fed models needing periodic refilling.
