pH 1-14 Wide Range Test Strips [Moisture-Proof Vial of 100 Strips]

It's spring and time to check my soil PH to see if I need to add granulated lime to my lawn. I remembered from High School chemistry class using litmus paper to check PH so rather than send out a soil sample I decided to search for litmus paper and do it myself. After searching through dozens of offerings from one of the giant online retailers, I couldn't find any that had all 5 star reviews; many reviewers stating they didn't believe it was actually litmus paper but just colored paper and no matter what they tested, the results were the same. I upped my game and went to Walmart.com and found one with all 5 star reviews. So I purchased it. I did have to pay for shipping, but it came the next day as promised. To verify this product was real, I tested it in baking soda in distilled water, distilled water, and vinegar. It actually worked as hoped. I took pictures of the results of the testing just in case I wanted to return it. Sure, a lab test would take the results out to a couple of decimal points, but all I need to know is do I need ag lime or not.
