Hey Cereal, ventilation is not something I'm very familiar with. I understand that concept and it will be rather easy to set up a system as there is a window right there but quite frankly, I don't know what kind of fan to use nor what power. Any advice? Also, the front opening hasn't got a door on it yet, that's the last step, although it's a tiny room and may very well not even need a door. I think it's warmer in there that it is in my bedroom at the moment haha.
