How Can Stress Be Measured?

Posted on

Watering

Watering is the best way to measure how stressed out your plant is. If you notice that the plant is not getting enough water, then you know that it’s time to give it some. A good rule of thumb is to check the soil level once per week. If the soil is dry, then add some water. If the soil is wet, then let it sit until it dries out.

Temperature

Temperature is another great way to tell if your plant is stressed. If the temperature goes above 90 degrees Fahrenheit (32 degrees Celsius), then you need to lower the room temperature. If the temperature drops below 50 degrees Fahrenheit (10 degrees Celsius) then you need to increase the room temperature.

Light

Light is the third way to measure stress. If the lights are on all day, then you know that the plant is stressed. If they are off at night, then you know that you need to turn them back on.

CO2

CO2 levels are measured by using a carbon dioxide meter. When the CO2 levels are high, then you know that your plant is stressed. When the CO2 level is low, then you need to increase it.

pH

pH is measured by using a pH meter. When the pH is high, then you know your plant is stressed. Low pH means that your plant is stressed and needs to be watered.

Ozone

Ozone is measured by using an ozone monitor. When the ozone levels are high, then your plant is stressed.

Humidity

Humidity is measured by using a hygrometer. When the humidity is high, then your plant needs to be watered. When the humidity is low, then you should increase the amount of water being added to the pot.
