G.A.S Intelligent Humidity / VPD Controller for SonicAir Pro - Dedicated VPD Control for the SonicAir Pro Humidifier
Best for: growers who already own, or are buying, a G.A.S SonicAir Pro Humidifier and want it running on automatic VPD or humidity control.
Our thoughts
This is a compatibility-specific version, not a universal controller - it's built and powered specifically to work with the SonicAir Pro Humidifier. If that's the humidifier you're running, the direct pairing means one less power supply to find space for. If you're not running a SonicAir Pro, this isn't the right controller for you - check G.A.S's universal Intelligent Humidity Controller instead.
The G.A.S Intelligent Humidity / VPD Controller for SonicAir Pro Humidifier is a dedicated version of G.A.S's humidity controller, wired specifically to work with the SonicAir Pro. It draws its power through the connection cable to the humidifier itself, so there's no separate power supply to install.
Like the standard Intelligent Humidity Controller, it uses a 3-in-1 probe to read temperature, humidity and light level, then switches the SonicAir Pro on and off to hold your target - either a set relative humidity or a calculated VPD level appropriate to your growth stage. It has four operating modes covering humidity or VPD control, each available as a constant target or with separate day and night settings, and includes a built-in data logger that records temperature and humidity for up to 7 days so you can review how your room has actually behaved.
How it compares
This is a purpose-built pairing rather than a general-purpose controller.
- Versus G.A.S's universal Intelligent Humidity Controller: the universal version works with any mains-powered humidifier or dehumidifier; this version is locked to the SonicAir Pro specifically, in exchange for drawing power through the humidifier's own cable.
- Versus manually running the SonicAir Pro on its own controls: this adds automatic VPD or humidity-based switching plus day/night differentiation and a 7-day data log.
- Versus TrolMaster's DSH humidity device modules: TrolMaster's modules work with a wider range of third-party humidifiers but need a compatible Hydro-X base station to function.
If you're committed to the SonicAir Pro, this gets you VPD-based automation without buying a universal controller you don't need the flexibility of.
Usage guidance
This controller is designed exclusively for the SonicAir Pro Humidifier - please note it is not compatible with other humidifiers.
Connection
Connect the controller to your SonicAir Pro Humidifier via the supplied connection cable; power is drawn from the humidifier itself.
Probe placement
Position the 3-in-1 probe centrally within the canopy for accurate temperature, humidity and light readings.
Choosing a mode
Select humidity or VPD control, and choose constant or day/night targets to suit your growth stage.
Reviewing data
Use the built-in 7-day data logger to check how temperature and humidity have actually tracked in your room.

Who this is for
- Growers who own or are buying a G.A.S SonicAir Pro Humidifier specifically
- Anyone who wants VPD-based automatic control rather than running the humidifier manually
- Growers who want a historical record of their room's humidity and temperature performance
Not suitable if you're running a different humidifier - the universal Intelligent Humidity Controller is the right choice in that case.
Our take
Pairing the controller directly with the SonicAir Pro keeps installation simple and gives you genuine VPD automation rather than manual guesswork, provided you're running the right humidifier for it.
If a SonicAir Pro is already part of your setup, or on your shopping list alongside it, this is worth picking up. Does exactly what it should, day in, day out.
