Cooling and Humidity fan
I installed a cooling and humidity fan after running the shed with a basic setup for a while, I realized the the shed was lovely and warm but the humidity was very low.
I realised the temperature and humidity were very much intertwined, as the one goes up the goes down.
With an average humidity of over 60% in England, I decided I had to bring in air from the outside.
To achieve this I installed a 120mm PC fan in the corner of the shed.
The fan is installed on the side of the shed where the sun never shines at any time of the day.
It pulls air from between the shed wall and the insulation itself.
This way the air is always cool and humid when it is pulled in.
