First time boiling in a shack this year and have a 4x8 cupola, it has flip-out windows in place of the normal cupola doors. and I suspect they're framed in a way that is reducing the size of the openings.
I'm getting good amount out the windows but typically have a vapor level about 80" off the ground (height of the big door in the front). After boiling for a few hours, the roof gets saturated and then it starts raining inside. I can't keep doing this or i'll rot the building from the inside out.
is there a formula to determine the CFM of steam generated by boiling sap?
is there a good way to get a fan up in the cupola to boost ventilation? or am I better off building a hood and steam vent?
this was taken on a crystal clear, low humidity night, only boiling around 40-45gph

This was last night when the humidity was sky-high.Visibility was realistically 36", and the cloud level was only 30-36" off the ground. It was a disaster. i thought i was going to have to shut down because it was so bad, couldn't see in the pans, and almost had a foam over in one of the channels. was boiling 45gph last night. this was before it "got bad".

Once the front moved through, i was able to get back to "normal" like the first picture. but cannot continue long term obviously. I need to get it resolved before i can go any faster in my pans. as i'd like to be up around 60-70 gph?
