Are Commercial Wall Mounted Dehumidifiers Worth It for a Grow Room

Commercial wall-mounted dehumidifiers are often worth it for a grow room, depending on the size of your operation and environmental control requirements.

 

Advantages of Commercial Wall-Mounted Dehumidifiers for Grow Rooms

Precise Humidity Control

Keeping relative humidity (RH) in the ideal range (40–60%, depending on the grow stage) is critical to prevent mold, mildew, and bud rot.

Wall-mounted units are typically more accurate and consistent than portable models.

Space Efficiency

Being wall-mounted, they free up valuable floor space for plants, equipment, or easier movement.

Durability

Designed for continuous operation, unlike residential or portable units that may burn out quickly in high-demand grow settings.

Drainage and Automation

These units usually come with direct drain options and can be integrated into automated HVAC or environmental systems, making maintenance easier and reducing downtime.

Energy Efficiency at Scale

The commercial wall mounted dehumidifier is more energy-efficient when scaled properly to the size of the room, leading to long-term cost savings versus running multiple small units.

When Is It Worth It?

Grow Room Size: Over ~200 sq ft or with high plant density.

Climate: High ambient humidity areas (e.g., coastal or tropical climates).

Crop Value: High-value crops like cannabis benefit greatly from precise humidity control.

24/7 Operation: You want low-maintenance, set-and-forget reliability.

 

Additional Considerations of Using a Wall Mounted Dehumidifier

Upfront Cost

Higher initial investment—often $1,000 to $3,000+ per unit.

Installation

May require professional installation (wiring, mounting, drainage setup).

 

A commercial wall mount dehumidifier is worth it for medium to large grow rooms or professional setups where humidity control is essential. For smaller or hobbyist growers, the cost may outweigh the benefit unless you're dealing with extreme humidity or high-value crops.
