GDX Instructions

GHX Specs

This Automatic Hydroponic Sensor & Dosing Sets Itself Apart With It's Large Display Screen, 14-Recipe Memory, Up To Five Sensors, & Up To Six Dosing Pumps, Data Logging & Multiple Communication Ports.

GrowControl GXH is a precision digital data logger and controller for automated nutrient dosing using AgrowDose peristaltic dosing pumps. Available with temperature, pH, conductivity, O.R.P., D.O. and flow sensor inputs. Optional flow sensor can stop dosing when there is no flow and allows for “proportional” dosing mode injecting chemicals according to the flow rate.

Color LCD display and button interface allows instant access to sensor readings, guided calibration, alarms, historical graphing and more. Multi-recipe memory stores 14 different configurations for quick changes according to growth phase. Dose up to 6 different chemical parts. Internal memory logs over 20,000 data points per sensor.

Precision sensors and rugged pumps offer reliable and accurate control. Built with FDA compliant tubing, the pumps inject chemicals quickly into water lines up to 25psi. Long-life pump heads are easily replaced in seconds without tools. The controller's large built-in color display provides an easy to use interface for monitoring the sensor readings and configuring the dosing settings.

The GXH hydro sensor continuously monitors the sensor probes and compares the readings to “target” set points for pH, conductivity (EC) and ORP (optional.) If the readings are outside of the allowed range, the pumps will sequentially dose according to the configured recipe, repeating until the targets are achieved.

Each pump has a programmable delay time to separate parts and/or add a delay between the cycles.

Included With The Mini Dosing System:

  • GrowControl GXH Controller
  • pH, EC, and temperature sensors
  • Available in a quad, or penta, or hexa pump set up
  • OPTIONAL: ORP & DO Sensors
  • OPTIONAL: Mounting Panel Kit (ships constructed with mounting panel, sensor manifold, and selected sensors & pumps)

The GDX can be paired with the GrowControl GCX Cultivation Control System for ultimate control of your growing operation. When paired with the GrowControl GCX Controller, you not only gain the ability to control all aspects of your facility's climate and hydroponics systems, you gain the option to run your GDX dosing system from the comfort of your home with remote access capabilities. Potential problems and issues are sent to you at an instant via text or email too, so you never have to worry!

Add Agrowtek’s SXL electronic optical liquid level sensor and water valve kits to the stock tank to automate the water level control and replenish the tank with water. This set up is perfect for those looking to automate their system entirely. Learn more here.

Agrowtek also offers an easy solution for firmware updates and data logging, using the Agrowtek LX1 AgrowLink. When using the LX1, you can hook your GDX system up to your pc for even more control. Learn more here.

To make sure you set your system up how you truly like and not just how you can get it, Agrowtek systems use standard MODBUS protocols and can be controlled by MODBUS devises using Agrowtek's LX2 ModLink. Learn more here.

Agrowtek Pumps

Easy Set Up

Connecting The GXH Controller & Peristaltic Pumps

The pump can be connected to the GXH dosing controller with a standard RJ-45 ethernet cable and is powered by the dosing pump’s power supply through the cable.

Controller can be used as a stand alone monitor when using it's own power supply.

GDX To Pumps

Setting Up Your Pumps For Dosing

Normal pump rotation is CW. The left tube is inlet (suction) and the right tube is outlet (pressure.)

Connect tubing with barbed fittings as shown. Tubing lengths may be as long as 50ft. Check for proper flow with the prime function.

Use the LCD menus to configure each pump and the the system parameters and then put the pumps into RUN mode to begin auto dosing.

Sensor Set Up & Usage

Connecting Your Sensor Probes To The SXHM Controller

pH, EC, ORP & DO sensors are equipped with “BNC” style connectors; push on and then turn to lock in place.

Temperature probes have a screw terminal block. Make the connections according to the label on the transmitter. The terminal block may be removed for easier wire installation or for service.

GDX to Probes

Sensors Require Continuous Contact

GDX systems require the sensors to be continuously in contact with the water in order to properly manage the dosing pumps. Probe can be located in the reservoir tank, or may be installed inline with a continuously recirculating water flow.

pH & ORP probes must remain wet to avoid damage. Do not allow probe tips to dry!
