About Quest
Quest is the industry leader in professional-grade grow room dehumidification. Their units are engineered specifically for the high moisture loads, elevated temperatures, and continuous-duty demands of indoor cannabis, vegetable, and horticultural production.
Unlike residential dehumidifiers, Quest units are built to handle high ambient temperatures (up to 95°F+), continuous 24/7 operation, and the extreme humidity levels generated by large canopies under intense lighting. The Quest 335 and Quest 465 are the most widely used commercial grow room dehumidifiers in North America.
Quest also offers inline duct-mount units, ceiling-mount models, and the Dual 335 for very large rooms. All Quest units integrate with environmental controllers including TrolMaster and Priva for automated climate management.

Quest — Frequently Asked Questions
What size Quest dehumidifier do I need for my grow room?
Sizing depends on your room's square footage, canopy size, lighting wattage, and ambient temperature. As a rough guide: Quest 335 handles ~3,000 sq ft, Quest 465 handles ~4,000 sq ft. Call us at 419-725-2450 and we'll calculate the right size for your specific setup.
Why use Quest instead of a regular household dehumidifier?
Household dehumidifiers are not rated for the high temperatures (80°F+) typical of grow rooms and will fail quickly under continuous operation. Quest units are engineered specifically for grow room conditions and are built for 24/7 continuous duty at elevated temps.
Do Quest dehumidifiers work with TrolMaster?
Yes. Quest dehumidifiers can be integrated with TrolMaster and other environmental controllers via dry contact triggers or 0-10V dimming inputs, allowing automated humidity control as part of a complete climate management system.
Can I get commercial pricing on Quest dehumidifiers?
Yes. Our Commercial Program offers custom pricing for commercial facilities, commercial growers, and wholesale buyers. Apply at toledoindoorgarden.com/commercial-apply or call 419-725-2450.
