The look and feel of this kits are consistent with the high quality we're used to from the rest of Garden Tutor's lineup. It requires a sample of soil to be mixed with water and then let settle so that the soil drops to the bottom. It is best to go with the three that align below the blue pad, and that is your pH. This takes a bit of work and it helps to do this in a well-lit room or by a sunny window to accurately assess the color change against the color chart.

It includes a detailed full color ph testing handbook with lime and sulfur application charts. It works well, easy, and good instruction booklet included. It is easy to use but strongly recommend you let the sample sit the full eight hours before testing. The kit does give some recommendations if you have to treat your soil.
