TrolMaster - Humidity Device Station Plug (DSH-2 / DSH-2U)

The TrolMaster DSH-2 Humidity Device Station Plug allows growers to connect and control standard humidifiers or dehumidifiers directly through the Hydro-X environmental control system. Designed for simple humidity devices that operate with a manual dial, this plug enables automated humidity management inside a grow tent or grow room without needing built-in humidistats.

Maintaining stable humidity is critical for plant health, nutrient uptake and proper root development in hydroponics, coco or soil grows. By connecting a humidifier or dehumidifier to the Hydro-X system using the DSH-2, growers can automatically manage humidity levels throughout vegetative growth and the flowering stage, helping prevent common environmental problems that reduce yield and bud density.

The DSH-2 is rated for 240V operation and provides reliable plug-and-play control for compatible humidity devices.

Key Benefits

• Integrates standard humidifiers or dehumidifiers with the Hydro-X controller
• Helps maintain stable humidity levels in grow tents and grow rooms
• Supports healthier plant development during vegetative growth and flowering
• Plug-and-play design for quick installation
• LED power indicator for easy status monitoring
• Reliable environmental control for hydroponics, coco and soil grows

How It Solves Grow Problems

Humidity swings are one of the most common problems in indoor growing environments. Excess humidity can lead to mould, weak stems and poor bud density during the bloom stage, while low humidity can slow vegetative growth and limit nutrient uptake.

The DSH-2 solves this by allowing the Hydro-X system to automatically switch humidifiers or dehumidifiers on and off to maintain the correct humidity range. This creates a stable environment in your grow room or grow tent, improving plant health, reducing stress and helping growers achieve stronger flowering and higher yields.

This device is designed specifically for simple dial-based humidifiers. For advanced humidifiers with built-in control panels or humidistats, a TrolMaster HS-1 Humidity Station is required.
