Wet walls are a popular and efficient way of cooling large greenhouses. Here are a few facts you may not know about wet walls:

Owning wet walls in your greenhouse will be useful when the climate is drier, as this method works as an active cooler. They are most suitable when humidity levels are low in a hot climate.

  1. The design of the wet wall looks like a honeycomb and is made up of cellulose material to avoid degradation and the build-up of moss.
  2. The gutter at the top of the wall is where the water trickles down into a collection pipe, which then enters and passes through a filtration system and recirculates.
  3. The combination between wet walls and extraction fans will reduce the temperature by 10 – 15 degrees. On one side of the wall, a bank of wet walls is placed and on the other side is a bank of extraction fans.
  4. Create a hybrid system for extremely hot days! Use a wet wall during the day and natural aspiration in the evening.
  5. Wet walls are mainly used by large commercial establishments due to the cost and the installation.
