Hey guys when fermenting in freezers that are modified for temp controls and such, what happens to the fumes (CO2) that are burped off and the freezer I sealed shut.

Does the freezer eventually burp? Especially if you had 2 primary's going?

Just don't stick your head in there when there's a bunch of CO2 built up. Not particularly dangerous, but taking a deep breath full of CO2 is NOT an enjoyable experience...found that out after my CO2 tank had a leak I didn't know about.

haha imagine a freezer burping. Reminds me of something you'd see in that Brave Little Toaster movie

The door seals are to prevent rapid air exchanges, not complete seals. The excess CO2 will escape but there will be a pool of CO2 inside.
