Best Soil Moisture Meter

Do the plants in your garden look a little underwhelming? Do you feel like you are adding the wrong amount of water to your plants? Are you unsure if your soil is too alkaline? If you answered yes to any of those questions, a soil moisture meter is perfect for you.

Designed to be plunged into the ground, a moisture meter will give you a reading that can help you calibrate your watering cycle. If you got a lot of rain recently, you can now know if your plants still crave more. This simple but powerful tool really makes your job a lot easier.

Some of the fancier models also give you the ability to check the pH levels in your soil. Now you can verify if your soil is too alkaline or acidic for what you are trying to grow.

Below I review the best 4 moisture meters available.

MoonCity 4-in-1 Soil Moisture Sensor Meter Review

This meter is a jack of all trades. It can provide four different readings all from the same probe. Simply stick the approximately eight inch long probe into the soil you would like to measure. You will be able to test the soil moisture content, temperature, pH value, along with the intensity of the sunlight in that spot.

All of your results are displayed on an easy to read LCD screen. The results show up almost instantly.

The screen is back-lit so you can read it in all sunlight conditions. Unlike some of the other meters the Moon City is powered by one 9 volt battery which is not included.

However the auto shut off feature really saves your battery life. I like this meter a lot, it is more expensive than some of the other reviewed options, but you get more bells and whistles.

3-in-1 Soil Test Kit by HealthyWiser Review

This meter by HealthyWiser is an analog version that offers three measurements. Similar to the Moon City meter you can measure the moisture content, pH level and light intensity.

This meter however does not measure soil temperature. This meter requires being left in the soil for a longer period of time, at least 10 minutes.

It is also important to clean the probes thoroughly between each measurement.

This powerful little meter works great for gardening, and you can use it inside or outside. You now no longer have to worry if you are over or under watering your plants.

REOTEMP MM17 Backyard Moisture Meter Review

The MM17 by REOTEMP is a bit different than the other reviewed options. The first thing you will notice, is the probe is much longer than other styles.

The probe on the MM17 is 17 inches long which really gives you the ability to determine moisture content at a much deeper level. You are not able to measure pH levels, or sunlight content.

This model is a simple, rugged, beast that does what it is supposed to very well. It works by measuring the electrical conductivity relative to the salt content in your soil.

This model is easy to calibrate, simply take a portion of your soil, and add water to it until it is at your desired wetness.

Change the dial to “5” and you are now calibrated! One AAA battery is included to power your plants new best friend.

Luster Leaf 1825 Rapitest Digital Moisture Meter Review

The Rapitest by Luster Leaf is a simple to use meter, that displays results in an easy to read digital format. What I like about this meter is the instant moisture results.

Some meters make you wait for results, this option lets you check numerous soil locations quickly.

A nice touch is the included plant list that recommends proper moisture readings.

Powered by the included batteries you get a long life on this meter based on the simplicity of the digital output. Luster Leaf also puts out a “mini” option. I don’t recommend this version as it tends to report inconsistent results.

Luster Leaf designs and engineers this product in the United States.
