Sigrow "S humidity" is a measurement of Volumetric Water Content (%) = Volume Water / (Volume Total) * 100. Where Volume Total = Volume Water + Volume Air + Volume Soil/Minerals/Substrate.

Tips: We recommend you to provide calibration points in the range where your substrate tipically is.
Maximum water substrate holds in a stable way: A useful point in the saturation point. How to get that calibration point? Simply water the pot to the maximum capacity, let it drip for 1 hour and measure its weight.
Weight Fully Dry Pot: Leaving the pot in the sun may not fully dry the substrate, we recommend to dry the soil in an oven or microwave.

EC reference: Take your EC reference at S humidity > 25%.
