GrowControl™ GCX Series

The cultivation control solution that modern growers can depend on for reliability and flexibility to meet challenging requirements. Manage, monitor, and control all aspects of your facility's climate, irrigation and hydroponics systems including: HVAC temperature & humidity control, light dimming & spectrum control, crop steering irrigation, CO2 injection and alarming, nutrient dosing and more. Always be aware of potential problems immediately with onboard email and text alerts, and always be in control with FREE remote access from your phone or PC.

Managing even the most complex environments is a simple task with a sleek and intuitive interface, extensive control programming capabilities and robust, easy-to-install hardware. As many as 100 Agrowtek GrowNET™ devices can be connected to the GCX system, and 200 GrowNET™ devices can be connected to the GCX+ system. Devices connect using standard Ethernet cable for robust and economical installation.

Built on over a decade of commercial experience, Agrowtek's GCX controllers are the most advanced and economical in the industry. Large scalability allows a facility to start simple and add devices as needs change and the business grows.

GrowNET™ Devices

A large variety of GrowNET™ digital peripherals are available for sensing and control integration. Each GrowNET™ device consumes a single device address on the GCX system's GrowNET™ device network (GCX = 100 addresses, GCX+ = 200 addresses.)

A standard environment sensor counts as a single "GrowNET™ device" but it can read temperature, humidity, light and CO2. Similarly, an 8-output relay such as the RD8i counts as a single "device" on the GrowNET™ network, but it can control eight different pieces of equipment.

Environment Sensors

Reliable, accurate climate sensors featuring temperature, humidity, ambient light and other optional sensors such as CO2 ppm. Add one or more sensors per growing environment to monitor and control cooling, heating, humidity, CO2 and more. View Environment Sensors

Relays & I/O

Contol all aspects of your facility with a variety of I/O and relay modules including relay dry contacts for HVAC control, DC outputs, discrete & analog inputs, 0-10V lighting control, reversible motor controls, and more. View Relays & I/O

Irrigation Control

Advanced control for multi-zone irrigation management including moisture sensor feedback driven crop steering irrigation capabilities or timed irrigation events. View Moisture Sensors

Hydroponics Sensors

Precision hydroponics sensors featuring temperature, pH, conductivity, oxidation reduction potential (ORP) and dissolved oxygen (DO) options allow the GCX system to manage and control nutrient and pH levels in irrigation stock tanks and recirculating hydroponics systems. View Hydroponics Sensors

Dosing Pumps

Automate pH control and nutrient dosing with rugged and economical AgrowDOSE™ pumps designed for injecting nutrient solutions, pH buffers and other chemicals. Pumps can draw solutions up to 10ft vertical lift and do not require manual priming. Peristaltic action resists fouling or clogging even with thick fluids. View Dosing Pumps

GrowNET™ Hubs

GrowNET™ HX8 device hubs expand one GrowNET™ port into eight more ports. Locate hubs in rooms to connect multiple devices to a GCX system through a single cable run. HX8 hubs provide power to most devices from the hub ports (power over cable) simplifying installation. Hubs are transparent on the network and not considered in the device count. Recommended maximum cable length is 1000ft. View Hubs

Remote Access & Updates

GCX systems include a standard RJ45 Ethernet network interface for internet connectivity, with WiFi as an additional connection option. A internet connection allows the use of built-in email alerts, remote VNC access and online updates without any subscription fees. Any standard VNC application for mobile or desktop will be able to remotely control and access the GCX system. The GCX system works with most standard SMTP email servers including Gmail and can send messages out to multiple recipients. System firmware updates are done via the internet with simple press of a button to initiate a check for updates. If updates are found they can be automatically downloaded and installed.


Data Logging

The GCX system will log data internally on the system's 2+ GB internal memory. Four (4) USB ports are provided for exporting data logs to memory stick as well as for other optional devices such as the WiFi module or keyboard and mouse. Data is logged as a standard .CSV format file which can be imported into spreadsheet programs or custom applications.

Control Functions

GrowControl™ GCX controllers have a powerful and intuitive graphical programming interface with a toolbar of control functions. Control functions can be added to a work space to create the 'logic' needed to control the environment. 'Work spaces' are often are modeled after the physical spaces they control such as rooms or zones. There is no limit to the number of workspaces or control functions that can be created.

Standard control functions include:

  • Clock Timers
  • On/Off Delay Timers
  • Cycle Timers
  • Thermostats
  • Humidistats
  • Integrated HVAC control w/VPD
  • Light Dimming & Spectrum Controls
  • CO2 Injection, Exhaust & Alarming
  • Motor Position Controls (Vents/Shades/Curtains)
  • Irrigation Stage Timers
  • Crop Steering Irrigation w/Moisture Sensors
  • Tank Level (Fill) Control
  • Nutrient & pH Dosing
  • Analog Output Modulation
  • Sensor Averaging
  • Custom Alarming & Messaging
  • Math
  • Logic Functions
  • More...

Control functions may be basic, or may be linked together to create logical steps where complex control is required.

Industrial Quality

Agrowtek Manufactures the GCX series controls almost entirely including the enclosure, motherboard, I/O boards and peripheral components in-house. Our integrated manufacturing technology allows custom processes and design for the highest quality while achieving the lowest cost. All of the circuit boards are 100% inspected, tested and conformal coated for resistance to moisture and dust. GCX systems run on a dedicated Linux OS with industrial flash hard drive for security and reliability. High performance quad-core processor with passive cooling technology means the system runs smooth and silent.
