G.A.S INTELLIGENT HUMIDITY CONTROLLER (IHC) DUAL

G.A.S IHC Dual – Intelligent Humidity & VPD Controller for Grow Rooms and Hydroponics

Take complete control of your indoor growing environment with the G.A.S Intelligent Humidity Controller (IHC) Dual, an advanced digital humidity controller designed to maintain precise moisture levels, optimise vapour pressure deficit (VPD) and support healthy plant development.

Manufactured by Global Air Supplies (G.A.S), the IHC Dual provides intelligent control of compatible humidifiers and dehumidifiers, helping maintain stable growing conditions throughout the entire plant growth cycle.

Unlike conventional humidity controllers, the G.A.S IHC Dual uses intelligent VPD technology to adjust humidity according to room temperature and plant requirements. By continuously monitoring environmental conditions, it helps create an ideal balance between temperature and relative humidity, supporting efficient transpiration, nutrient uptake and vigorous plant growth.

Featuring dual humidifier and dehumidifier control, the IHC Dual automatically manages compatible equipment to help prevent excessive humidity, condensation and sudden fluctuations in growing conditions.

The controller also features independent day and night settings, allowing growers to programme different humidity targets for each stage of cultivation.

Its integrated 7-day data logger records temperature and humidity readings, enabling growers to review environmental performance and make informed adjustments.

With an intuitive LCD display, advanced environmental sensors and straightforward controls, the G.A.S IHC Dual is an excellent choice for both experienced hydroponic growers and professional indoor cultivation facilities.

Why Choose the G.A.S IHC Dual?

Maintaining correct humidity levels is essential for plant health, particularly during propagation, vegetative growth and flowering.

The G.A.S IHC Dual takes environmental control beyond a basic humidistat by combining intelligent VPD management, automatic humidity regulation and historical climate monitoring.

Whether you're managing a small grow tent or a professional indoor growing facility, this controller helps create more consistent conditions while reducing the need for constant manual adjustment.

Choose the G.A.S Intelligent Humidity Controller Dual for precise VPD management, automatic humidity control and professional grow room climate regulation.

Please note: Humidifiers must remain within the controller's 320W rating. Dehumidifier control requires a compatible low-voltage control connection. Check equipment compatibility before installation.
