Ensure that the moisture sensor is dipped all the way into the substrate. For most accurate readings, place the sensor towards the center of the tank, and near the “dirt” parts of your soil (as opposed to rocks).



If problems still persist, recalibrate the sensor through the app. Go to Settings > Soil Probe Calibration.

Measuring soil moisture is not an exact science. You may need to do some trial-testings to get it right. To make the process easy for you, we have provided several tips below:    

  • The value read by the soil probe takes time to settle down: up to 30 seconds. Therefore, every time you reposition the soil probe, such as between calibration steps, give some time for the value to settle.

  • If you want a high-humidity climate, you should place the sensor in a dryer location: near the tank walls and where it is more rocky.

  • If you want a low-humidity climate,  you should place the sensor in a wetter location: towards the center and where there dirt that retains water well.

Calibration Steps:

  • Go to Settings > Soil Probe Calibration

  • Take the probe out of the unit and wipe it dry

  • Wait 15 secs before Pressing "Next"

  • Take the probe out of the unit and dip in the wettest part of the soil or dip it in a glass of water

  • Wait 15 secs before Pressing "Next"

  • You’re done! To test whether the calibration worked

    • Try simulating the wet soil condition by sticking the probe in a glass of room-temperature water.

    • Try stimulating the dry soil condition by wiping the probe dry and leave it in the open air.
