What Is the Ideal Soil Moisture Range?Updated 2 months ago

Soil moisture tension is measured in millibar (mbar).

Lower numbers represent wetter soil while higher numbers represent drier soil.

Many growing systems perform well in the 50–100 mbar range, though the ideal level varies depending on soil type, plant stage, and environmental conditions.

Step by Step Instructions:

1. Measure soil moisture using a tensiometer.

2. Compare the reading to the desired range.

3. Adjust the sensor slightly if needed.

4. Allow time for the soil to stabilize before adjusting again.
