Quest 155 Overhead Dehumidifier

The Climate Master CM-145 is a high-capacity dehumidifier designed for serious indoor growing environments and sealed grow rooms where humidity control is critical. Excess moisture during vegetative growth and especially the bloom stage can quickly lead to mould, weak plant health and reduced yield.

With powerful moisture extraction and strong airflow, the CM-145 helps maintain stable humidity levels so plants can focus on nutrient uptake, root development and producing dense flowers. It’s a strong alternative to popular sealed-room dehumidifiers, offering higher water removal performance while remaining fully compatible with Trolmaster climate control systems.

Key Benefits

• High-capacity moisture removal for large grow rooms and sealed environments

• Helps prevent mould, mildew and bud rot during flowering

• Supports healthy transpiration and nutrient uptake in hydroponic systems

• Improves plant health and bud density by stabilising humidity

• Compatible with Trolmaster Hydro-X via HS-1 humidity station

• Built-in programmable humidistat for standalone operation

• Strong airflow for consistent climate control across the grow space

• Suitable for hydroponics, coco and soil indoor growing setups

How It Solves Grow Problems

High humidity is one of the most common issues in indoor growing, particularly during heavy flowering when plants transpire large amounts of moisture. Without proper dehumidification, growers often face mould, powdery mildew and airy buds that reduce final yield.

The CM-145 removes excess moisture quickly, helping stabilise the grow room climate. This allows plants to transpire properly, improving nutrient uptake and supporting stronger vegetative growth and dense flowers during bloom. It is particularly useful in sealed rooms, large grow tents and high-intensity hydroponic systems where humidity rises rapidly.

How to Use

1. Install the unit within the grow room or sealed environment with adequate airflow space.

2. Connect to a drain for continuous water removal where possible.

3. Set the desired humidity level using the built-in digital humidistat.

4. For automated grow room control, connect the unit to a Trolmaster Hydro-X system using the HS-1 humidity station.

5. Maintain relative humidity appropriate for the growth stage (typically 55–70% during vegetative growth and 40–50% during flowering).
