And because the probes reach down deep into the soil, the readings are more accurate than simply digging your finger into the soil (the simple way to check soil moisture).
If you’ve never purchased a soil meter, you may not know what to look for. We’re going to make your life a little easier by sharing some of the best meters on the market. Here’s how to compare them:
- Stem Length: The meter’s stem length is important, especially if you’re growing plants in the ground and not containers. The longer the stem, the deeper you can reach down into the soil to get a truly accurate moisture reading. Choose a length that’s appropriate for your garden setup.
- Readings: Does the sensor only check the soil moisture level, or does it also check the pH and light levels? Knowing the pH and light levels will help you determine which adjustments need to be made (if any) to keep your plants healthy. If you only need to know the moisture levels, you can opt for a simpler, more budget-friendly meter.
- Ease of Use: Is the meter easy to use, or does it require a complicated setup? Most meters are simple plug-and-play devices, but more advanced sensors may require calibration. For professionals or serious gardeners, the latter option may be the right choice. For the everyday gardener, a simple meter may be better.

Buyer’s Guide – How to Choose the Right Moisture Probe for You
Choosing the right moisture probe can be difficult simply because most of the devices look and behave in the same way. Most sensors are also similar in price, which can complicate things. We talked about some of the most important things to consider when comparing your options. Here are some other things to keep in mind when choosing a meter:
- Power: Does the meter require batteries? Many do not, but some do. Check the power source of the model you’re considering, so you know what you’re up against.
- Reliability: How reliable is the meter? One good way to check the accuracy of a meter is to read reviews from other users. If the sensor’s readings are off, you’re sure to find people complaining of it online.
- Indoor or Outdoor: Is the meter suitable for indoor use, outdoor use, or both? Most – but not all – meters can be used both indoors and outdoors. Still, it’s important to check the product description to make sure the meter is compatible with your garden’s location.
- Cost: The cost of the probe is another consideration. Most meters are very affordable, but some are still more expensive than others. Decide how much you want to spend on a meter, and choose a model that matches your budget.
- Calibration: Does the probe require calibration? Some models, like the last one we reviewed, do require calibration before you can accurately test the soil. The benefit of calibrating the meter is that your results will be more accurate and tuned to your soil.
