    Easy for beginners

    The directions are very plain and easy to understand. All you need to know is an understanding of colors. Just take a sample of the fluid to be tested and add some drops of the Test Indicator. Compare the color of the sample to the chart on the back and see your pH. Be aware that the value won't be exact (like 5.8 or 7.4) It will just tell you an approximate value of acidic, neutral or alkaline. Then you can add pH UP or pH DOWN to adjust the fluid your sample came from. Be aware that the pH UP and pH DOWN are very concentrated and it might only take a few drops to adjust a whole gallon of fluid. I was very pleased with this product.

  • Good product, works great!

    Fist time using this kit. So far, so good. The test is easy to do and when I compare it to my digital pH meter they're extremely close. Product performs as advertised and it's very easy to use.

    I have used many different types of similar product. Quality product and very consistent from bottle to bottle. This is important to me as I use in large quantity.

  • Makes a world of difference for your plants

    To grow healthy awesome plants, you must adjust the pH (acid or base) of the water and/or nutrients to suit the plant. This product allows measurement and adjustment of that pH. The kit contains everything you need to measure and adjust so that it is close enough.

  • Great Product

    My county was water system ph level is off the charts high, so I have to lower the ph level before watering my out/door in/door plants. This product does a great job in doing just that.
