The Bluelab Wi-Fi Guardian is a continuous monitoring unit for growers who need eyes on their reservoir around the clock. It measures pH, EC/conductivity, and temperature simultaneously and pushes live data to the Bluelab Connect app — so you can track trends, get alerts, and act before a drift becomes a problem, whether you are standing in the grow room or not.

Continuous pH Monitoring Tracks pH around the clock so drift is caught immediately rather than at your next manual check.
EC & Conductivity Tracking Monitors nutrient solution strength in real time so you always know what your plants are being fed.
Remote Access via Wi-Fi Connects to the Bluelab Connect app for live data, historical logs, and customisable push alerts to your phone.
Temperature Measurement Reads solution or ambient temperature alongside pH and EC — everything you need in one wall-mountable unit.

Grower Tip
  • Calibrate your pH probe weekly using Bluelab pH 4.0 and 7.0 solutions — a calibrated probe is the difference between reliable data and guessing.
  • Set your app alerts to trigger 0.3 pH units outside your target range so you get early warning without constant phone-checking.
  • Store the probe tip in Bluelab KCl probe storage solution when not submerged — a dry probe degrades fast.

How to Use

1
Calibrate the pH probe — Before first use, calibrate using Bluelab pH 4.0 then 7.0 solutions. The Guardian walks you through it step by step.
2
Submerge the probe — Place the pH probe into your nutrient reservoir and secure the unit in a stable position within cable reach.
3
Connect to Wi-Fi — Open the Bluelab Connect app and follow the setup wizard to connect the Guardian to your 2.4 GHz network.
4
Set alert thresholds — Program your high and low limits for pH, EC, and temperature in the app to match your crop's target parameters.
5
Monitor remotely — Check live readings and historical trends from anywhere via the Bluelab Connect dashboard on your phone.
6
Maintain the probe — Recalibrate weekly and store the probe tip in KCl storage solution when not in use to extend its working life.

Frequently Asked Questions

Does the Wi-Fi Guardian work with 5 GHz Wi-Fi?

No. The Wi-Fi Guardian operates on 2.4 GHz networks only. Make sure your router has a 2.4 GHz band active and connect to that band during setup.

Can I monitor multiple grow rooms from one Bluelab Connect account?

Yes. The Bluelab Connect app supports multiple devices under a single account, making it easy to manage several reservoirs or grow spaces from one dashboard.

Does it keep working if my internet goes down?

No — remote alerts, logging, and app access all require an active internet connection. The unit will continue displaying live readings locally if Wi-Fi drops, but cloud functions pause until connectivity is restored.

How long does the pH probe last?

With regular calibration and proper storage in KCl probe care solution, Bluelab probes typically last 12–18 months. Replacement probes are available separately and use a standard BNC connection.

Is the Bluelab Connect app free?

Yes. The Bluelab Connect app is free to download and use. There is no subscription required to access monitoring, alerts, or data logging features.

Growers First, Retailers Second

Welcome to The Grow Guys

We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
