sounds like its giving you a total for soil and water which would be run off, stinky says check at run off,water you plants and dip the tab into the run off. by what you are explaining , you can check it b4 watering with that kit if you wanted to and adjust accordingly to get the right run off ph.which actually sounds to me like the right way to do it .
i dont know how accurate the soil part would be.i just bought a ph pen. measure run off. adjust accordingly. done

fiddyonefiddy Reviewed by fiddyonefiddy on . Help with checking pH So I've never checked pH before and I'm a little confused on how this is to be done. I have one of the liquid testing kits with the little capsules and the container with the color chart. So container has two lines. The first line, near the bottom, designates where you fill the soil up to, and the second line, way up at the top, designates where to fill the water to. It says to take your soil, filter out anything like rocks out of it, dry it out and mix it up good, and fill the container up Rating: 5
