Active Grow EDGE Series Automatic Grow Tent Humidification Kit

The Active Grow EDGE Series Automatic Grow Tent Humidification Kit combines a 4L ultrasonic humidifier with a dedicated sensor-based humidity controller for automatic humidity management in grow tents and other controlled growing spaces.

• Tank Capacity: 4L
• Mist Output: Up to 280 mL/h
• Run Time: 12–14 Hours
• Control: Automatic Humidity Regulation

Set your desired Start and Stop humidity levels, and the EDGE Humidity Controller automatically switches the humidifier on and off to maintain your selected range without constant manual adjustments.

Automatic Humidity Regulation

The EDGE Humidity Controller uses simple Start and Stop thresholds to manage the humidifier. When relative humidity falls to your Start value, the controller switches the humidifier on; once humidity reaches the Stop value, it switches it back off.

Sensor-Based Humidity Monitoring

The controller monitors relative humidity from 0–99% RH with 0.1% RH resolution, and its direct socket output handles up to 10A / 1500W.

4L Removable Water Tank

The humidifier features a removable 4-liter tank with a maximum mist output of 280 mL/h.

At maximum output, Active Grow rates the system for approximately 12–14 hours of operation per fill, reducing how often you need to refill.

Up to 30m² Coverage

The humidifier is rated for spaces up to 30m², although actual coverage will vary with environmental conditions. That makes it well suited to Walden White grow tents and other similarly sized controlled growing spaces.

Flexible Mist Delivery

An included flexible hose directs mist where it’s needed inside the growing area, and also lets the humidifier sit outside the tent while directing moisture into the growing environment.

Quiet Ultrasonic Operation

Ultrasonic atomization produces up to 280 mL/h of mist at a rated operating noise level of under 30 dBA.

Dehumidifier Control Capability

The EDGE Humidity Controller can also operate a compatible dehumidifier using its Start/Stop logic in reverse. A dehumidifier is not included with this kit.
