Moisture Meters FAQs

What Are Moisture Meters Used For?

moisture meter in soil

Moisture meters are used to measure the level of water in the soil. In a hydroponic system, they show the water content of the roots and/or growing solution. 

This is important because plant roots are underneath the surface of the earth. If you touch the surface of the soil with your hands, then you can’t get a good gauge on the moisture levels. Garden moisture sensors have a long probe that reaches further under the soil and can detect water. 

It is important to measure the water content of your soil so that you know if you are overwatering or underwatering. Plants need an optimal amount of water to grow. If they receive too much or too little water, they can’t grow properly.

Plants that receive too much water are more vulnerable to bacteria and fungi. This is because oxygen cannot penetrate the soil because of the high water content. This allows the growth of bacteria that damage plant roots. 

The lack of oxygen also inhibits the photosynthesis process and does not allow plants to grow to their full size. It can cause a buildup of gas and make the plant droop and rot. The damage of the roots also prevents them from absorbing water. Lastly, overwatering plants can make fruit rot. 

Underwatering plants is also harmful. Plants that do not receive enough water will reduce in size and eventually die. This is because water keeps plants upright and rigid. Without the moisture, they start to wilt towards the ground. They also cannot absorb enough nutrients to grow. 

Therefore, a moisture meter for plants can help you to monitor moisture levels. You can make sure that your plants receive the correct amount of water to grow healthy and strong. 

Do Moisture Meters Really Work?

level of wetness

Plant moisture meters give an accurate reading on the level of wetness in the soil. 

There are different kinds of garden moisture sensors:

  • Tensiometers
  • Electrical resistance blocks
  • Hand-held moisture meters

Tensiometers are a professional soil moisture meter that you can use to measure a wide variety of soils. You need to select the soil type and calibrate the tool. It measures how much water tension is in the soil by the movement of water. It gives an accurate reading that is calculated in centibars. 

Electrical resistance blocks can measure the moisture of soil because of the level of electrical conductivity. When there is more water around the block, it spreads the electricity and reduces the tension. The opposite happens when there is little water near the block. The resistance block calculates the tension and shows it in centibars. 

Hand-held moisture meters are the most common plant moisture meters. They have metal tips that conduct electricity. When there is moisture in the soil, it creates an electric current on the tip of the meter. This kind of moisture meter shows more general readings, usually low, medium, and high. 

Moisture meters for plants are usually very accurate. However, the handheld units are vulnerable to salt levels. If you use a fertilizer with high salt content, you may get an inaccurate reading. 

What Are Normal Moisture Readings?

All of the soil moisture meters on this list use a scale of 1-10. The analog models also include colorful sections that indicate levels of wetness from dry to wet.

Usually, a score of 1 indicates very dry soil. An opposite reading of 10 shows that the soil is very wet. Digital moisture meters for plants include a more precise reading, including one decimal place. 

If you are doing hydroponic gardening without soil, then your moisture readings indicate the moisture of the roots and growing solution. 

Normal moisture readings depend on the kind of plant that you are growing. Moisture meters often include a booklet that shows the ideal reading for different kinds of common plants. 

The following plants need low water content to survive:

  • Cacti
  • Succulents
  • Snake plants

Most plants need a moderate amount of moisture. These include common household plants like:

  • Begonias
  • Azaleas
  • Ficus
  • Philodendrons

Most plants start to suffer when there is a lot of moisture in the soil. However, ferns need a medium-high level of soil moisture to thrive. 

You should cross-reference your particular plants with the guide included with your moisture meter. You can also consult a soil moisture guide

When Should You Measure Moisture?

readings on moisture meters

You should measure the moisture level of your garden regularly. Make it a habit to take readings every day or every other day. You can even make a chart so you can refer to any changes in moisture content.

You should measure before adding more water. This will tell you how much or how little moisture you need to give to the plants. It is also best to measure at the same time every day. This allows you to account for external factors like sunlight and temperature. 

Measuring the moisture of your plants is also important if you start to notice any changes in growth. Yellowing leaves can be an indicator of disease, nutrient deficiency, or overwatering. Therefore, you should always measure moisture levels to rule out overwatering.

The Best Moisture Meters for Plants for Hydroponics

In conclusion, moisture meters are an essential tool in any kind of gardening setup, including hydroponics. They allow you to monitor water levels in soil, roots, and growing solutions. This allows you to avoid overwatering or underwatering your plants.

There are analog and digital garden moisture sensors. Both are easy to read. They usually have increments of moisture and watering guides, so you can see the ideal water level for your plants. 

We hope this guide has helped you to find the perfect moisture meter for your plants. Remember to measure on a regular basis and help your plants to thrive!
