What is a digital pH meter?

Knowing the pH of your soil or hydroponic system is very important. Growers need to be aware of whether their soil is acidic or alkaline so they can make adjustments. Water pH is one of the most critical aspects of hydroponic growing, as having water at the correct pH allows plants to easily intake nutrients for faster growth.

If you want to learn more about the testing your pH, along with many other aspects of of your grow, check out our complete guide on garden soil and nutrient solution testing.

A digital pH meter allows you to quickly and accurately test the pH level of your soil or nutrient solution. You can then take steps to rectify the situation if pH is too low or too high. For reference, plants need a pH level between 5.8-6.8.

Automating pH testing in your grow room

Not every grower has the time to use a digital pH meter every time they water or feed their plants. Or, maybe you're a commercial grower with a huge warehouse full of plants, and testing pH manually is not feasible.

Using a nutrient and pH doser will automate pH testing for you. These products will measure and adjust pH levels without you having to do anything, whether you are present or not. And, they even feed your plants nutrients at the doses you set - so you can essentially free yourself from the bulk of feeding/testing!

Are pH meters and test kits accurate?

The products we sell at Hydrobuilder are incredibly accurate and reliable. The higher quality products are more expensive, but their performance reflects this. On that note, let's talk about calibrating your pH pen or pH meter.

How do I calibrate my pH meter?

Using a calibrated pH meter is obviously really important. You will need to calibrate your pH pen before the first use to make sure you get accurate readings. You will also want to test your pH meter if you see a reading that may not make sense, every 30 days, or after changing batteries and cleaning.

You will use calibration solutions to test the pH levels, and if you want to learn how to do this, check out our guide on how to calibrate a pH pen.
