What Is the Ideal Humidity Level for a Greenhouse?
Humidity levels are important if you want to stave off moisture-related problems in your greenhouse. Ideal relative humidity levels vary, however, and are related to temperatures. For example, tropical plants require higher humidity levels as well as warmer temperatures. Therefore, it's important to house similar plants together so you can supply the plants in your greenhouse with suitable humidity levels. Does this Spark an idea?

Relative Humidity and Temperature
-
Ideal humidity levels are related to temperatures because warmer air contains higher moisture levels than colder air. For example a greenhouse that is at 91 percent humidity should sit at about 68 degrees Fahrenheit. To control humidity levels at certain temperatures, purchase a humidity gauge to determine what your moisture content is and then adjust the temperature.
Reducing Humidity
-
If the humidity level in your greenhouse is too high, closely adhere to your plants' watering requirements and install floor drains to reduce moisture and prevent condensation from taking place.
-
Proper Ventilation
-
Ventilation is also an important aspect to consider because proper ventilation aids in reducing high humidity levels. Appropriate roof vents, cross drafts and fans combine and circulate drier outdoor air with humid air inside a greenhouse.
