Let your crops flourish by giving them the optimal environmental conditions.

GC Climate Controllers replace the thermostat and humidistat for your HVAC and Humidity equipment. They are the best climate controllers available due to sophisticated settings that allow you granular control over your climate. Achieve precision Temperature, Humidity, VPD, and CO2 levels for your entire operation, no matter how many rooms you have.

The CC-HUM is a Climate Controller that is a direct replacement for a standard Humidistat.  It is used in conjunction with a CS-Series Climate Sensor, which provides humidity data for the Climate Controller to act upon.   The CC-HUM, together with a CS-Series Climate Sensor will fully automate your dehumidification/humidification climate system.  You have unlimited flexibility to create and tailor humidity settings to your exact specifications.  Create custom day and night settings, create custom humidity curves, and when used in conjunction with a CC-HVAC Climate Controller, you can set your climate parameters by vapor pressure deficit (VPD).  Climate curves allow you to set parameters for each hour of the Day and Night periods, so you can dial-in humidity to your exact specs.  The GrowCentral App allows you to manage as many different rooms and environments as you have in your facility.  You can even manage multiple facilities - all from just one app.  


  • Use with GC Climate Sensors for precision climate regulation.
  • Fast & easy to deploy - direct replacement for standard 24-Volt humidistats.
  • Converts Humidity equipment to digital IoT control.
  • 24/7 access to all of your climate functions and data from the GrowCentral app.
  • Independent Day and Night settings for all parameters.
  • Control climate by VPD to optimize plant metabolism.
  • Full control over hysteresis settings (dead band) to flatten your climate curve and maintain the most stable environment.
  • Full control over ‘short-cycle’ settings to prevent damage to equipment from rapid cycling.
  • Advanced algorithm automatically switches between Humidify & Dehumidify modes.
  • Set Climate Curves with specific humidity settings for each hour of the Day and Night.
  • When using in combination with a CC-HVAC Climate Controller, Set Temperature and Humidity by Vapor Pressure Deficit (VPD).
  • Set alerts if humidity parameters are out of desired range.
  • Manage and control unlimited Facilities, Rooms, and environments with the GrowCentral App.
