If you want to advance your hydroponics skills past the beginner level, you can try using a liquid pH testing kit. This is where you drop dye into the solution which changes color to indicate the pH level. These liquid pH testing kits are also available at your local hydroponic retail shop or online.
The most accurate way to test your pH levels is by using a digital pH tester. These digital meters are available in a number of price ranges with the simplest one being a “pen” style meter. You just insert the pH meter’s tip into the solution until a pH level reading is registered on the digital screen. These digital meters are available at any hydroponic retailer and are also widely available online.
Here are some digital pH meters different price ranges:
- Hanna Instruments Hanna Checker pH Tester ($45 approx.)
- HM Digital pH 80 Meter ($60 approx.)
- Bluelab pH Pen ($110 approx.)
