Quest 70 Overhead Dehumidifier

The Quest 70 Overhead Dehumidifier is a professional-grade humidity control solution designed specifically for indoor growing environments. In hydroponics and sealed grow room setups, plants release large amounts of moisture through transpiration. Without proper humidity control this can quickly lead to mould, slow growth, weak plant health and reduced yields.

Designed in the USA for controlled indoor cultivation, the Quest 70 removes excess moisture efficiently while running quietly and using less power than most conventional dehumidifiers. Unlike many consumer units that are rated under unrealistic conditions, Quest machines are engineered for real grow room environments, helping growers maintain stable humidity through vegetative growth and the bloom stage.

Key Benefits

• Removes up to 26 litres of water per day at 26.7°C and 60% RH

• Highly efficient performance at 2.2 litres per kWh

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

• Designed specifically for hydroponics and indoor growing environments

• Supports healthier plants, stronger flowering and improved yield

• Helps maintain ideal humidity for bud density and plant health

• Compact overhead design ideal for grow tents and sealed grow rooms

• Simple plug-and-play setup with optional ducting and condensate pump compatibility

• Quiet operation suitable for professional cultivation spaces

How It Solves Grow Problems

In indoor growing environments, every litre of water your plants absorb is eventually released back into the air. During heavy vegetative growth and especially during the bloom stage, this moisture can rapidly push humidity levels too high.

Excess humidity leads to several major cultivation problems including poor nutrient uptake, slow root development, mould risk, weak bud structure and reduced yields. The Quest 70 allows growers to maintain stable relative humidity throughout the entire growing cycle, helping plants focus energy on strong growth, dense flowering and improved plant health.

It is particularly useful in sealed grow rooms, hydroponic systems, and high-intensity lighting environments where plant transpiration rates are high.

How to Use

1. Position the unit overhead or suspended in the grow room using a compatible hanging kit if required.

2. Plug the unit directly into a suitable power outlet.

3. Allow the dehumidifier to run continuously to maintain stable humidity levels during vegetative growth and flowering.

4. Direct condensate drainage to a suitable outlet or optional condensate pump.

5. For optimal airflow management, ducting kits can be installed to direct intake and exhaust air where needed.

6. Replace the internal MERV filter every grow cycle to maintain efficiency and prevent airflow restriction.

Maintaining proper humidity with the Quest 70 helps create a stable environment where plants can thrive, supporting strong growth, improved flowering and higher quality harvests in hydroponic and indoor growing systems.
