G.A.S Intelligent Humidity Controller — Universal

G.A.S Intelligent Humidity Controller — Universal (Any Humidifier)

The universal version of G.A.S's intelligent humidity controller — works with any plug-in humidifier, not just the SonicAir Pro. Monitors temperature and humidity continuously, calculates VPD (vapour pressure deficit), and switches your humidifier on and off to maintain ideal transpiration conditions for plants.

Why growers choose the Intelligent Humidity Controller:

• Works with ANY plug-in humidifier — ultrasonic, evaporative, domestic or commercial — any 240V humidifier plugs in and is controlled
• VPD-based control — targets vapour pressure deficit rather than pure relative humidity, optimises plant transpiration
• Alternative RH mode — use straightforward humidity percentage if you prefer
• Prevents bud rot in late flower — the critical stage where humidity management makes or breaks harvests
• Replaces cheap hygrostats — proper monitoring with temperature-aware logic, not just a single humidity reading
• Grow-room-specific design — tuned to the humidity dynamics of tents and grow rooms

Who it's not for:

If you have a G.A.S SonicAir Pro specifically, the Pro version of this controller is optimised for that pairing. You'll need a humidifier separately — this is the controller only. For combined humidifier + dehumidifier + temperature + fan control, step up to the G.A.S Enviro Controller V2.
