Each test has it's own plastic "test tube" and color-coded capsules for mixing. Uses a color code for test results, so the readings will not be to-the-digit accurate, but should give a good idea as to what the soil conditions are. Will do soil readings for a variety of flowers, fruits, trees, shrubs, houseplants, herbs and turf. pH test only takes a few minutes, but other three tests may take up to 24 hours depending on soil.
