TrolMaster Day/Night Digital Humidity Controller (BETA-6)

The TrolMaster BETA-6 Digital Humidity Controller provides precise humidity management for indoor growing environments such as grow tents and grow rooms. Controlling humidity is essential for maintaining healthy plants, preventing mould issues and supporting optimal conditions during both vegetative growth and the flowering stage.

The BETA-6 allows growers to plug in either a humidifier or dehumidifier and automatically control it based on the humidity levels in the grow space. With separate day and night humidity settings and a built-in photocell, the controller automatically adjusts humidity targets depending on whether the grow lights are on or off. This helps maintain the correct climate throughout the entire grow cycle.

A remote humidity probe with a long cable ensures accurate humidity readings near the plant canopy, allowing growers to monitor the environment where it matters most.

Key Benefits

• Controls humidifiers or dehumidifiers automatically
• Separate day and night humidity settings for improved climate control
• Built-in photocell detects lighting cycles automatically
• Remote humidity probe with 16 ft cable for accurate canopy readings
• Helps prevent mould, mildew and humidity-related plant stress
• Simple digital interface for easy setup and monitoring
• Compatible with devices up to 10A

How It Solves Grow Problems

Humidity fluctuations can cause serious issues in indoor growing environments. High humidity during the flowering and bloom stage can lead to mould and bud rot, while low humidity during vegetative growth can slow plant development and reduce nutrient uptake.

The BETA-6 helps stabilise humidity levels by automatically activating a humidifier or dehumidifier when conditions move outside the set range. The day and night humidity settings allow growers to maintain slightly different environmental conditions depending on the lighting cycle, which better matches natural plant behaviour.

By maintaining consistent humidity levels, growers can reduce environmental stress, support healthier plant development and improve overall yield and bud density.

How to Use

1. Connect the humidity sensor to the BETA-6 controller.

2. Position the sensor at canopy height inside the grow tent or grow room for accurate readings.

3. Plug a humidifier or dehumidifier into the controller outlet (maximum 10A).

4. Connect the controller to a power outlet.

5. Set the desired day and night humidity levels using the digital display controls.

6. The built-in photocell will detect lighting conditions and automatically switch between the programmed day and night humidity settings.
