Why Do I Need To Clean And Calibrate My pH Probe? 

Over time, plant debris will get stuck to your probe, making it harder for your probe to read the pH of your water accurately. This is totally normal for probes that are submerged in water 24/7.

The pH probe is a necessary tool in any hydroponic system because without it there's no way to monitor the pH range of your setup. pH stands for potential hydrogen, and it's the measurement of how acidic or alkaline a solution is. 

Plants are delicate creatures that need to be in the correct pH to thrive. If your probe is left dirty and uncalibrated, it may overestimate or underestimate the acidity of the water, which could harm your plant. This is why it's important to quickly check the cleanliness of your probe each week when you drain and fill your Grobo, and check on the calibration status of your probe each month.


How To Calibrate Your pH Probe: 

With Grobo, it's simple! Follow the instructions in the app and your probe will be calibrated in no time. Watch this video for step-by-step instructions! 


How Often Do I Need To Replace My pH Probe? 

We recommend replacing your pH probe once a year for optimal performance. This will ensure your plants are being exposed to the correct pH, which will result in awesome harvests.
