One thing somebody told me once has always helped me when watering. Think,of the soil as a dry sponge. When dry, it won't pick up anything spilled on the counter. But once you wet it, it easily picks up spills. This is akin to watering a dry plant just once. The soil is too dry to absorb much of the water. But when you do a second pass, the soil is moist enough to absorb as much as it needs.
I like the idea of using the meter as a comparison to my finger. When my finger says "water me," I can then use the meter and see if its results are the same.
I too tend to overwater. I'm hoping the meter might help me learn not to.
I'll let you know how my comparison goes.
