Bluelab pH Controller Wi-Fi – Automatic pH Dosing & Monitoring System
Take control of your nutrient reservoir with the Bluelab pH Controller Wi-Fi, an intelligent automatic pH monitoring and dosing system designed for hydroponics, recirculating systems and professional horticultural applications.
The controller continuously measures your reservoir 24/7 and automatically doses pH Up or pH Down when required, helping maintain a stable pH range without constant manual testing and adjustment.
With built-in Wi-Fi connectivity and Edenic mobile access, growers can remotely monitor pH readings, receive alerts and stay connected to their reservoir from virtually anywhere.
Why Choose the Bluelab pH Controller Wi-Fi?
Maintaining stable pH is essential for efficient nutrient availability and healthy plant growth.
In hydroponic and recirculating systems, pH can change throughout the day as plants absorb water and nutrients. Frequent manual testing and adjustment can be time-consuming and may lead to inconsistent results.
The Bluelab pH Controller Wi-Fi automates this process by continuously monitoring pH and making controlled adjustments when necessary.
This helps provide:
- More stable reservoir pH
- Better nutrient availability
- Reduced manual testing and dosing
- Greater consistency between adjustments
- Improved reservoir management
- Remote visibility through your mobile device

Automatic 24/7 pH Control
Once your desired pH target is configured, the Bluelab pH Controller continuously monitors the reservoir and determines when an adjustment is required.
The system activates its built-in dosing pump to add the selected pH adjustment solution automatically.
Instead of making large adjustments all at once, the controller uses controlled dosing intervals that allow the solution to circulate and mix before taking another reading.
This approach helps minimise:
- pH overshooting
- Sudden pH fluctuations
- Excessive dosing
- Unnecessary chemical use
Built-In Variable-Speed Peristaltic Pump
The controller includes an integrated variable-speed peristaltic pump, eliminating the need for a separate dosing pump in many installations.
With a maximum flow rate of 120ml per minute, the pump provides controlled delivery of pH adjustment solution into the reservoir.
The system can be configured for either:
pH Up – when your reservoir typically becomes too acidic.
or
pH Down – when your reservoir typically becomes too alkaline.
The controller regulates one dosing direction at a time.
Wi-Fi Monitoring with Edenic
Built-in Wi-Fi allows the Bluelab pH Controller to connect with Edenic, giving growers convenient access to their system from a compatible mobile device.
Through Edenic, you can monitor reservoir conditions and stay informed even when you are away from your grow area.
Connected functionality can help you:
- View current pH readings
- Monitor reservoir performance
- Receive alerts
- Check system status remotely
- Respond more quickly to unexpected changes
This is particularly useful for commercial growers, larger hydroponic systems or anyone who cannot continuously monitor their reservoir in person.
High and Low pH Alarms
The Bluelab pH Controller includes configurable high and low pH alarms to help identify conditions outside your preferred operating range.
If pH moves beyond your chosen limits, the system can alert you so the reservoir can be inspected before the problem affects plant performance.
Safety Lockouts for Controlled Dosing
Automatic dosing systems require safeguards to help protect plants from excessive chemical addition.
The Bluelab pH Controller incorporates safety lockout functions designed to stop dosing when abnormal operating conditions are detected.
These safeguards provide an additional level of protection against situations such as prolonged dosing or unexpected reservoir behaviour.
Automatic Resume After Power Loss
A temporary power interruption does not necessarily mean your pH management has to remain offline.
The controller can automatically resume dosing operation following power restoration, helping restore your automated reservoir management without requiring constant manual intervention.
Temperature Compensation
pH measurements can be affected by temperature.
The Bluelab pH Controller uses temperature compensation to support accurate pH measurements as reservoir temperature changes.
This helps provide more consistent monitoring across changing grow-room and nutrient-solution conditions.
Why Stable pH Matters in Hydroponics
Plants rely on an appropriate pH range to access nutrients efficiently.
When reservoir pH moves too far outside the desired range, certain nutrients may become less available even when they are present in the nutrient solution.
Maintaining stable pH can help support:
- Efficient nutrient uptake
- Healthy root development
- More consistent plant growth
- Reduced nutrient availability problems
- More predictable reservoir management
Automatic pH control is especially valuable in recirculating hydroponic systems where reservoir conditions can change continuously.

- Nutrient tanks
- Fertigation systems
- Professional cultivation facilities
- Automated grow environments
Maintenance Recommendations
Proper probe maintenance is essential for reliable pH measurement.
For best performance:
- Keep the pH probe clean
- Never allow the probe to dry out
- Store the probe in appropriate storage solution
- Calibrate regularly using fresh calibration solutions
- Inspect the dosing tube and pump periodically
- Replace worn pump tubing when required
Using Bluelab calibration solutions and a Bluelab Probe Care Kit can help maintain measurement accuracy and extend probe life.
Important pH Dosing Safety
Always follow the manufacturer's instructions when using pH Up or pH Down solutions.
Highly concentrated pH adjusters should be diluted appropriately before automatic dosing where required.
Different nutrient formulations, reservoir sizes and adjustment products can respond differently, so begin with conservative dosing settings and carefully observe how your system reacts.
Avoid rapid or excessive pH correction, as sudden chemical changes may destabilise the nutrient solution or cause nutrient precipitation.
