Quest 100 Compact Commercial Dehumidifier

The Quest 100 Compact Commercial Dehumidifier is a high-efficiency climate control unit designed for smaller grow rooms and tightly controlled indoor growing environments. In hydroponics and indoor growing, excess humidity can quickly lead to mould, weak plant health and poor bud density during flowering. The Quest 100 removes large amounts of moisture while using very little energy, helping growers maintain stable humidity levels throughout vegetative growth and the bloom stage.

Built with advanced M-CoRR multi-coil technology and modern R454B refrigerant, this compact unit delivers powerful moisture removal while keeping running costs low. Its small footprint makes it ideal for grow tents, smaller grow rooms and cultivation spaces where reliable humidity control is essential for protecting plant health and improving overall yield.

Key Benefits

• Removes up to 100 pints of moisture per day (at 26.7°C / 60% RH)

• 7.5 pints per kWh efficiency for lower energy costs

• M-CoRR multi-coil refrigeration technology for high moisture removal efficiency

• Built-in MERV-13 filtration improves grow room air quality

• Plug-and-play operation with no complex installation required

• Onboard digital dehumidistat with self-diagnostics

• Dark Mode reduces light pollution during the flowering cycle

• Corrosion-resistant base designed for humid grow environments

• Automatic restart after power outages

• Designed and assembled in the USA

How It Solves Grow Problems

Humidity spikes are one of the most common problems in indoor growing environments, particularly during the bloom stage when dense flowers release large amounts of moisture. High humidity can lead to mould, poor airflow and reduced bud density.

The Quest 100 helps stabilise humidity in grow rooms and grow tents, allowing plants to focus energy on root development, nutrient uptake and flower production. Its MERV-13 filtration also captures dust, mould spores and airborne particles that circulate in indoor growing environments, supporting cleaner air and better plant health across hydroponic systems, coco or soil setups.

Because of its compact design, the unit can easily fit into smaller grow rooms where space is limited but climate control is still critical for maintaining strong yields.

How to Use

1. Position the dehumidifier inside the grow room on a stable, level surface with adequate airflow around the unit.

2. Connect the unit to a suitable power supply.

3. Attach a drain hose to the condensate outlet for continuous drainage if required.

4. Use the onboard digital dehumidistat to set your desired humidity level.

5. Allow the unit to run continuously to maintain stable humidity throughout vegetative growth and flowering.

6. Check and replace the MERV-13 air filter regularly to maintain airflow and system efficiency.
