Let’s take a look together!

Select a Model

There are many different models of moisture meters. All devices are affordable. With a moisture device, you can measure how acidic the soil is, the light it receives, and so on. Get started by choosing a moisture measuring device that meets the criteria you want to measure in the plants you grow.

Control the Soils of Your Plants

Start by measuring the toe of the plants in your home. Most plant owners are generous with watering their flowers. However, excess water causes plant death. So press the pointed end of your moisture meter into the ground three-quarters of the way. In this way, you will see the moisture content of the bottom soil.

Measure According to Your Plant

Some plants love water, while others grow in dry soil. If you know all the plant’s growth characteristics, give water according to the moisture meter data or take it out to the sun to tolerate excess water.

Determine Your Plant’s Moisture Needs

Some plants need moderate moisture for further growth and flourishing. For example, begonias. If you have a color-adjusted moisture meter, the red color indicates that your plant needs water. If the color is blue, the soil of your plant is very watery. That’s why you shouldn’t water your plants until your moisture meter turns red or green.

Don’t Forget to Clean

It would help if you wiped your moisture meter probe after each measurement. The sharp tip of your device, which allows you to get the most accurate result, should not remain grounded or moist.

One more warning! It would help if you did not immerse the moisture meters directly in water. It will directly cause it to malfunction.


We have shared the best moisture meters for plants in 2021 that you need while fulfilling your plants’ maintenance conditions. We have gathered the criteria you need in our buying guide while choosing from hundreds of options you will encounter on the market! You can make the right choice by paying attention to these criteria!

Power Selection

In general, there are moisture meters that can work with and without batteries on the market. Those without batteries have a needle on them, and you can measure the moisture in your soil with this needle, and it is inexpensive. Battery-powered moisture meters require AA or AAA batteries. These batteries are long-lasting and can even show you the humidity on a digital display.

The only thing you need to be careful about is that you don’t forget to turn off your device when you’re done. Thus, you can use it for a long time by minimizing battery cost and usage.


Can moisture meters be wrong?

The only way to be sure of this question may be to take your soil sample to an agricultural specialist after measuring the device you purchased. According to the researches, the margin of error has been observed much higher in non-invasive measurement devices.

As a reason, it has been shown that the measurement material of the device is metal inside or behind.

Indoor / Outdoor Use

Do you have plants both in your home and in your garden?

Then it would help if you chose a moisture meter suitable for use both indoors and outdoors. It will shield you from stamina. You can select a simple and inexpensive model for your indoor measurements. However, the devices that we will choose to use in your outdoor areas, resistant to external factors, metal or plastic-type devices will be suitable.

It is also essential to the climate you live in. You may prefer heavy-duty moisture meters instead of hand-held meters, as some temperatures are extremely cold or extremely hot.

3 in 1 Moisture Meters

Your plant’s soil doesn’t just contain moisture. As you know, soils also contain pH values ​​and sunlight. Thanks to the 3 in 1 moisture meters, which have approximate prices with moisture meters, it is possible to measure all the plant-soil values. These scales are the primary devices to be preferred for sensitive plant growers.

Thus, when you encounter a problem with your plant, it becomes easier for you to evaluate other factors other than moisture.


If you want to get the soil values quickly and accurately, you should evaluate your moisture meter to see the sensitivity before purchasing. That is, sometimes you have to immerse your moisture meter in the soil vertically, sometimes you have to immerse it slightly inclined. It would help if you tried different angles to get the fastest result in the most accurate location.

If your moisture meter is sensitive enough, you will get the best result at minimum depth without changing the angle. Don’t forget to get help from your dealer!


What is an Acceptable Percentage of Moisture for Drywall?

The humidity level of each house is variable. The humidity rate that develops depending on your home’s location and the climate are acceptable between 5% and 12% when it comes to drywalls.

How Much Water Does a Plant Need Per Day?

Irrigation takes a critical place for your plants to grow. 4 to 6 liters of water per day are required for your large water-loving plants in your home. However, if you have smaller or newly planted plants, they should consume an average of 3 liters of water per day. If the soil is dry when you measure the first 2.5 cm of the soil with a moisture meter, it is time to rinse.

On sweltering summer days, the number of irrigation for some plants may increase to two or three per day.

Is it Bad to Water Plants at Night?

For your water-loving plants to grow healthier, you should not water them at night. In plants receiving sunlight, water is tolerable; your plant, which absorbs as much as it needs, can evaporate the remaining part with sunlight.

However, at night, this is the opposite. Your plant cannot tolerate water, and roots and leaves that remain wet are the perfect opportunities for fungus and moisture formation. For this reason, take care to water your plants during the day.

Can a Moisture Meter Detect Mold?

We cannot say that a moisture meter can detect mold. Mold formation can be observed on roots and leaves. However, your moisture meter helps you see moisture that can cause mold, and take precautions. Especially needle-free moisture meters allow you to determine much more moisture areas. You can also learn the growing conditions of your plants and take precautions to avoid excessive moisture.

Will Mold Die if it Dries Out?

Molds do not die by themselves. They are motionless only when there is no moisture. If your humidity increases, mold will increase in the right proportion. It is possible to keep decay away from your plants with professional help and moisture prevention steps.


Plants are beneficial creatures for humans. Many plant breeders want to have a reasonable care period for these creatures they have. Humidity is very harmful to plants that can be grown indoors and outdoors. They need moisture meters to prevent moisture build-up that ends in a short time with plant death.

The product range they can find in the market is quite broad. We have listed the best moisture meters for plants in 2021 for you. You can protect your plants by choosing one of these devices in different categories.

Our pick from this list was the Sonkir Soil pH Meter, which ranked first. We are no longer worried about our plant with the help of this device, where we can obtain both the moisture content of our plant and the pH balance it needs.
