What is one method of evaporative cooling used in greenhouses?

One effective method of evaporative cooling used in greenhouses is the implementation of misting systems. These systems work by releasing fine droplets of water into the air within the greenhouse. As the water evaporates, it absorbs heat from the surrounding environment, leading to a drop in temperature. This process helps to create a more favorable climate for plant growth, particularly during hot weather, by maintaining optimal temperatures and humidity levels.

Misting systems are especially useful as they not only cool the air but can also provide necessary moisture to plants, enhancing their overall health and growth. This technique allows for efficient temperature regulation without the need for mechanical cooling systems, which can be energy-intensive and costly.
