PH TEST STRIPS - ENSURE YOUR WATER PH IS CORRECT!
Having the correct PH range is crucial to ensuring your plants grow their best. Unlike other strips on the market, these PH test strips have a narrow range better suited to water/soil/coconut coir applications - especially for marijuana.
Simply dip a strip into your water (or push some damp soil on it) and compare it to the chart on the package for instant results. It's that simple!
Ph Range: 5.5 - 9.0
