Air Locks Needed for Lagering?

[zgardener]

Stupid NOOB question, but I am lagering an American Style Lager in my fridge, and am soon to move my Maibock to secondary and begin to lager that in the same fridge.
The question is if I really need drilled bungs with an air lock for my better bottle secondary vessels during lagering, or if I could just use solid bungs. Because parts of my fridge are low clearance and I cannot fit the BB with the air lock in those spaces, but I can w/ only a solid bung.

If you have the potential for air-exposure, you need an air lock. If you know beyond a certainty of a doubt that fermentation is complete, go ahead an put a solid bung on it. I had a lager in the fridge for over a year and didn't put a solid bung on it.

I would put an airlock on it, no matter how far along it is.

I'll take a gravity reading, if it hasnt gone down since I took it a few weeks ago I'll go ahead and put a solid bung in it cuz I dont wanna have to take my deli meat drawer lol

A Second vote for an Air Lock. Putting a Solid Bung into a Carboy is asking for trouble.

You _could_ just put some sanitized foil on it or something.
