How to Measure and Adjust pH for Gardening - Hydrobuilder.com

You can measure pH using a pH pen, a soil pH pin, or a pH test kit.

A pH pen, like the one from Blue Lab, is turned on and placed into the liquid you want to measure. Within seconds, you will get a pH reading.

A soil pH pin is similar to a pH pen but is used for measuring the pH of soil. You use the probe cover to make a pilot hole, then place the probe into the hole for a reading.

A cheaper alternative is to use a pH test kit like the one from General Hydroponics. You take a sample, add a few drops of the testing solution, shake it, and compare the color to the chart on the bottle.

To adjust pH, you can use pH up and down solutions. Start by measuring the pH of your water and adding the necessary solution to bring it to your desired pH level. It may require some experimentation and rechecking.

No, it is important to only use one part when adjusting pH. For example, if your pH is too high, only use pH down. If you overshoot, use something like water to raise the pH before adding more pH down if necessary.

It is important to measure and adjust pH before watering your garden for the best results.
