Ec number for water
WebThe saturation index (SI) of water is a relationship between pH, salinity, alkalinity and hardness. It assesses the potential of the water to cause scaling and precipitation (positive number) or corrosion (negative number). • If SI is between −0.5 and +0.5, there is little … WebSimply add pH-balanced water; in the case of growing in pots or containers, water until fully saturated and then allow to drain. You would then measure the EC of the run-off. Repeat this process; then compare the EC of the run-off with your original root zone EC reading.
