Quest 70 Dehumidifier Duct Kit (4038599)

The Quest 70 Dehumidifier Duct Kit is designed to give growers greater control over airflow when using the Quest 70 Overhead Dehumidifier in indoor growing environments. In sealed grow rooms and hydroponic systems, proper air distribution is essential for stable humidity control. This kit allows growers to attach ducting directly to the dehumidifier, helping direct intake and exhaust airflow exactly where it’s needed.

By improving air circulation and moisture removal across the grow room, the duct kit helps maintain a consistent environment during vegetative growth and the bloom stage. This ensures better humidity management, supporting healthy plants, improved nutrient uptake and stronger flowering performance.

Key Benefits

• Designed specifically for the Quest 70 Overhead Dehumidifier

• Includes 8″ duct collars for quick and secure installation

• Allows connection of supply and return ducting

• Improves airflow distribution across the grow room

• Helps maintain stable humidity levels for indoor growing

• Ideal for sealed grow rooms, grow tents and hydroponic systems

• Supports consistent environmental control for healthier plants and improved yields

How It Solves Grow Problems

In indoor growing environments, poor airflow can lead to uneven humidity levels across the canopy. Some areas of the grow room may remain too humid while others stay dry, which can cause mould issues, weak plant development and inconsistent flowering.

The Quest 70 Duct Kit allows growers to direct airflow from the dehumidifier to specific areas of the grow room. This improves overall moisture removal and ensures humidity is controlled evenly across the space. By improving environmental stability, growers can maintain ideal conditions for strong root development, healthy vegetative growth and dense flowering.

How to Use

1. Turn off and unplug the Quest 70 dehumidifier before installation.

2. Attach the 8″ duct collars included in the kit to the intake and return air ports on the unit.

3. Secure compatible 8″ ducting to the collars using clamps or appropriate fasteners.

4. Position ducting to direct airflow where humidity control is required within the grow room.

5. Ensure ducting runs are kept as straight as possible to maintain optimal airflow performance.

6. Power the unit back on and monitor humidity levels to ensure balanced airflow throughout the grow space.
