my vino is unplugged as my basement right now is about 60*. I also do not have any oust fans and I havent noticed any problems, as long as you open it every few days you should be fine.
My main questions is how could you not open it every few days? These sticks are our babies and they need love and attention! I have to get in my humi just about every other day min. Why? Idk.. just because!
