Soil Meters & Test Kits

The soil pH meters and test kits we carry here at Hydrobuilder will help you maintain a healthy soil to grow the best plants possible. We also carry soil moisture meters and NPK test kits to help you figure out what's going on in your grow, and take steps to fix it if necessary.

There are a number of reasons why you should test your garden soil. It is important to know the conditions you are growing in, so you can adjust accordingly. If you are growing in soil, a meter or test kit is an absolute must to ensure you are growing in a proper environment.

How do you use a soil pH meter?

To test your soil pH, insert the probes on your pH pen into the soil. Readings will display the pH level digitally. It is important for your soil to be between 6-6.8 pH.

The pH level of your soil directly affects the plants ability to absorb nutrients. If your pH is too low or too high, you will see slower growth than you otherwise could!

How do you correct pH in soil?

If after you test the soil you find that it is outside the ideal range, you need to take steps to remedy this. If you have a few supplies at home, it can be very simple.

pH adjuster kits contain pH up and pH down, and make correcting pH easy. These are natural alkaline or acidic chemicals that can be added into the soil.

If you are an organic grower, you can use amendments to adjust pH organically, but they won't act as fast. To lower pH in your soil, try using peat or sulfur. To raise your pH, try using lime.

Can you use a soil pH tester in water?

If you are trying to test your water or nutrient solution for an indoor garden or hydroponic system, you will need a hydroponic pH meter. These do not feature long, skinny probes like a soil meter. Some of the best pH pens for use in water are the Bluelab pH Pen, Sure Test Pro pH Pen with Replaceable Probe, and Hanna Instruments Continuous pH/TDS/Temp Monitor.

What does a soil test tell you?

The most basic soil test kits will determine the pH of the soil, such as the Luster Leaf Products Rapitest Digital pH Meter. Plants need a pH of between 5-6.5 in order to absorb nutrients, and if your soil is preventing this from happening, it needs to be corrected using a pH adjusters.

Some soil meters can also test for moisture. Growers sometimes like to cycle the soil between very moist and very dry to active certain processes, and using your finger to guess how damp your soil is can prove ineffective. The Active Air 3 - Way Meter is actually capable of reading pH, moisture, and sunlight!

More advanced multi-use tools can also test for specific macronutrient profile in the soil, also known as NPK. This test reveals how much nitrogen, phosphorus, and potassium are in the soil, and you can adjust these nutrients to line up with your goals and the plants current stage. The Luster Leaf Products Rapitest Electronic 4-Way Analyzer is one of these tools which is capable of measuring four different aspects of your soil!

Automating your garden soil pH, moisture, and NPK testing

Are you a commercial grower, or a hobby farmer with limited time to tend to plants?

If so, you should strongly consider automating your soil testing with a device from the Sure Test line of products. These soil meters take continuous readings of your soils moisture, salinity, temperature, and EC, and send them to a database on your computer or smartphone.
