Over or under-watering a plant is one of the most common causes of death of houseplants. The plants in the containers are entirely dependent on the person who supplies the water for their survival — because of this, providing the right amount of water at the right time is essential for nourishing healthy plants. You can determine the amount of water in your soil, as well as the right time to water a plant using a soil moisture meter. Many garden centers and nurseries sell necessary soil moisture meters that contain a probe, as well as a reading line.
- Examine the packaging supplied with your moisture meter. Many meters of soil are sold with instructions for reading the dial printed on the packaging or on literature that is enclosed in the meter.
- Find on the playback dial. Reading dial of a soil moisture meter will be divided into a scale of 1 to 10. This scale will be divided into three colored sections. The first three digits on the dial will be marked in red. This indicates that the soil is dry. The four middle numbers are green. This suggests that the soil is moderately moist. The last three digits on the dial are colored in blue. This means that the soil is saturated with water.
- Insert the soil probe vertically into the soil midway of a container between the edge of the box and the plant. Probe deep in a large saucepan and superficially in a small box. Look at the dial to note where the needle is resting to indicate the amount of water in the soil.
- Look again at the instructions. A list of common houseplants can be printed there, which indicates what dial is reading the floor should have for each plant. For example, succulents like aloe should have the floor with the dial in the red zone between numbers 1 and 3. If the soil moisture meter pushes the needle above 3, the plant has been Too much water.
- Remove the probe from the floor by pulling on the probe handle. Never remove a meter of moisture from the sensor. Clean the floor meter and probe with a soft cloth before using it again.
Interpretation of the results obtained by the hygrometer
In general, if you go to a store to buy a device, the seller comes with a manual, and another sheet called a calibration sheet. The installation, the technical description, and the calibration of equipment must be written in this little book. There is also the accuracy rate of a hygrometer, which is expressed in percent preceding a plus or minus sign. What does the accuracy rate mean? I answer you by illustrating with examples; Assume that the accuracy of a hygrometer to be used is 5 %, it indicates on the screen, during the reading, a value of 75 %; those which means that taking into account the accuracy that the humidity is about 80%.
The percentage displayed on the screen is the humidity. Interpreting is the fraction of evaporated water containing in the air. Take, for example, an air volume of 100ml, put our hygrometer in it. By reading the moisture content on the screen of the instrument, we find a value of 70% that is to say the 70ml of this air is water vapor.
If the percentage is small for air; it is said to be dry because it is devoid of water. Also, it is light and less dense. On the other hand, if the humidity level is too high, which means that the vapor in the air is dominant. The air is called “humid air” and dense.
