are 2 kinds of fans needed for climate control in the greenhouse. These
fans use little electricity. For only a few pennies a day, you can create
a healthy greenhouse environment.
1. Air Circulation:
It is important to have a fan to circulate air through the foliage of plants.
This brings a fresh supply of needed carbon dioxide to the leaves. Air circulation
also prevents diseases that like to start in areas of cold and stagnant
2. Heat Destratification:
Because warm air rises, a small fan is needed to pull warm air off the ceiling
and push it down to the plants on the benches and floor. This is very important
in the winter months, and helps reduce heating costs.
