How to Select an Evaporative Cooler Size


Evaporative coolers work well in dry climates where the humidity is below 50%. Air is cooled 10° to 20° F by water evaporation as it is drawn through the cooler and into the greenhouse.

Determine the volume of your greenhouse - length x width x height.

This number is the recommended "CFM rating" for your greenhouse cooler. Select an evaporative cooler with this or a higher CFM rating.
