Global Air Supplies Intelligent Humidity Controller Dual (IHC MULTI)

The Global Air Supplies Intelligent Humidity Controller Dual (IHC MULTI) is an advanced humidity management system designed to maintain precise moisture levels in indoor growing environments. Built for use in grow tents and grow rooms, this intelligent controller can operate both a humidifier and a dehumidifier simultaneously, preventing humidity spikes and maintaining the stable conditions plants need for optimal growth.

Humidity plays a critical role in hydroponics and indoor growing. When moisture levels fluctuate, plants can experience stress that slows vegetative growth, reduces nutrient uptake, and negatively affects flowering and yield. The IHC Dual continuously monitors humidity and temperature, automatically adjusting connected equipment to maintain the ideal environment for strong plant health, efficient root development, and consistent results throughout the growth cycle.

Key Benefits

• Dual control for both humidifiers and dehumidifiers from one controller
• Compatible with any 240V humidifier, including SonicAir Pro units
• Intelligent humidity management to prevent environmental spikes
• Built-in 7-day data logger for monitoring temperature and humidity trends
• Customisable day and night humidity settings
• Detachable probes for flexible sensor placement
• LCD display for simple setup and monitoring
• Energy-efficient operation that only runs equipment when needed

How It Solves Grow Problems

Humidity fluctuations are a common issue in indoor growing spaces. High humidity during the flowering or bloom stage can cause mould and reduce bud density, while humidity that is too low during vegetative growth can slow plant development and limit nutrient uptake.

The IHC MULTI solves these issues by automatically balancing humidity levels. By controlling both humidifiers and dehumidifiers, it prevents sudden spikes or drops in moisture that can stress plants. Stable humidity supports healthy transpiration, stronger root systems, and improved nutrient uptake in hydroponic systems, coco, or soil grows. This helps growers maintain the correct vapour pressure deficit (VPD), resulting in healthier plants, tighter buds, and higher yields.

How to Use

1. Install the controller outside your grow tent or grow room in a convenient location.

2. Place the detachable humidity probe inside the grow space at canopy height.

3. Connect your humidifier and dehumidifier to the controller’s output sockets.

4. Set your desired humidity levels using the LCD interface.

5. Configure separate day and night settings to match your lighting cycle.

6. The controller will automatically monitor humidity and activate connected devices to maintain stable conditions.
