pH and EC Monitors and Controllers

Continuous WiFi monitors and automated pH and EC dosing controllers for serious and commercial grows.

Frequently Asked Questions

Do I need WiFi or an app to use these controllers?
Some models, like the Bluelab Guardian and Pro Controller, connect to WiFi for remote monitoring and alerts. Others run standalone without an app, so check the individual listing if you specifically want or want to avoid app dependence.

Can these controllers dose nutrients automatically, or only pH?
It depends on the model. Some, like the PeriPods, are dosing pumps built for automated nutrient delivery, while others focus on monitoring and pH correction only. Check what each unit is designed to dose before buying.

How long can a monitor run unattended between checks?
This depends more on your reservoir size and plant demand than the monitor itself, since the monitor only measures, it does not top up water. Continuous monitors are best paired with a reservoir sized to your typical check-in interval.
