    GrowControlTM GC-ProXL Climate & Hydro Controller (includes basic climate sensor)

    Complete Cultivation Control Systems for Climate & Hydroponics Control

    Same great features of GC-Pro, more more built-in I/O and expansion capability!

    The most flexible, advanced control solution that modern, demanding growers can depend on for reliability and ease of operation. Monitor, managae, and control all aspects of your enivronmental climate equipment and hydroponics systems including automatic dosing. A built-in industrial grade micro-processor contains all of the user's settings, reads the attached sensors and then turns equipment on or off automatically.

    What Can AgrowTek Pro Control System Do?

  • Sends Email / MMS Alerts - Get Updates from Any SmartPhone
  • Access Your Grow From the Internet
  • Monitor from afar via Video Cameras
  • Control EVERYTHING, lights, fans pump, dosers, heating, door/ window switches, outside temps, motion or smoke detectors

    Complete Climate Control

    Fully automate multiple zones with independent controls for cooling, heating, humidification, dehumidification, CO2 injection and ventilation with boost timing, light timers and light flip box controls, and more! Featuring a large array of different timers including irrigation timers, precision repeat cycle timers (in minutes, seconds, or hours) 24-hour timers, 24-hour cancellation timers, combination 24-hour cycle timers, off-delay timers, re-start delay timers and hour meters. Greenhouse models feature multi-stage heating, cooling and humidity control for advanced integration of hvac, fans and vents.

    Fully Automated Hydroponics Dosing (applicable models)

    GrowControlTM systems take the manual work out of maintaining a hydroponics system. Fully automate and schedule reservoir changes, nutrient dosing and pH control. Mix volumetric batches or add Agrowtek's hydro sensor kit to monitor and maintain pH, EC and temperature automatically.

    AgrowTouchTM Touch Screen

    An industrial strength touch screen interface is available which allows fast and easy access to all settings in the controller including manual over-rides of all equipment, adjustment of all settings, graphical display and history of all sensor readings, alarm history display and more. On-screen help provides the operator with quick tips and describes each function of the controller. For economical or starter applications, the GC-ProXL can be adjusted and monitored with the free PC software.

    Power Relays

    The controller's low-voltage 24Vdc outputs are wired to Agrowtek's RX, CX and RD series relays to control equipement power. Mix and match relay models to suite your environment and equipment control requirements. MX motor control relays can be used to operate vent and curtain motors forward and reverse. The GC-ProXL can also be wired to existing or custom electrical relays panels with the "RD" series of dry-contact relays.


    The GC-ProXL is built with Agrowtek's exclusive FlexnologyTM which allows the grower to tailor the controller's functions precisely to their operation's requirements. A large 'tool box' of control functions is provided for the user to select from and assign to outputs as required by the equipment to be controlled. Additionally, important features are included such as:Lamp hot-fire prevention, Output delay sequencing (to prevent load spikes), Alarms and alerts, Trending and data logging, Remote internet access and control.

    Multi-Zone Control
    The GC-Pro can operate multiple independent climate hydroponics zones from one controller depending on the model.

    Free PC Software
    GrowControlTM GC-Pro includes a powerful PC application offering full control of the system. The GC-Pro can be operated without a touch-panel interface and with only PC software for economy applications. Features include graphical and spread-sheet data logging, status and control of inputs, outputs and sensor readings, all controls and settings, email alerts and more. (connect via serial port, or ethernet connection available for additional cost)
