Sonic Air PRO Humidifier + IHC Pro Dual VPD Controller

Automated VPD control that holds humidity exactly where plants want it

Dialling in humidity and VPD (vapour pressure deficit) is one of the hardest balancing acts in indoor growing, and the Sonic Air PRO Humidifier + IHC Pro Dual VPD Controller bundle takes it off your hands. It pairs a powerful 6.5 L/hr ultrasonic humidifier with an intelligent dual controller that raises humidity to your VPD target automatically, then backs off as conditions stabilise. The controller can also drive large grow-room dehumidifiers such as Quest units, giving one setup control over both ends of the humidity swing across the whole plant lifecycle.

What's Included

• G.A.S SonicAir Pro humidifier
• 150mm outlet funnel
• Sonic Air Pro Dual VPD Humidity Controller

Key Benefits

• Automatic VPD targeting adjusts output to the correct range for the current growth stage
• Fine 6.5 L/hr ultrasonic mist raises humidity fast without soaking the canopy
• Two-way humidity control connects to dehumidifiers, including Quest units, for full management
• Better nutrient uptake by holding plants in their proper transpiration range
• Quiet operation under 35 dB with automatic shut-down when water runs low
• Suitable for hydroponic, coco and soil grows

Stop the humidity swings that stall growth and uptake

Low humidity in early veg is a common cause of slow growth, poor nutrient uptake and stressed plants, especially in smaller tents where conditions swing quickly. The SonicAir Pro generates a fine ultrasonic mist that lifts humidity the moment the Dual VPD Controller detects a drift outside target, keeping root and leaf development on track without constant manual tweaking.

How to Use

1. Position the SonicAir Pro in the grow room, or outside the tent, with the 150mm funnel directing mist into the space.
2. Connect the humidifier to the Sonic Air Pro Dual VPD Controller.
3. Place the controller's sensor inside the grow space at canopy level.
4. Set your target VPD or humidity for the current growth stage.
5. The controller activates the humidifier automatically whenever humidity falls below the set range.
6. If needed, connect a compatible dehumidifier to the controller for complete two-way regulation.
