Fermentation Chamber airlock?

[edie]

purchased a 7cu ft freezer and installed an external thermostat to use as a fermentation chamber. do i need to install some sort of an airlock?

thanks for any input

No, while the fermentation will produce CO2, there is more than enough empty space for it not to be a problem.

made the mistake of taking a whiff. checking for the sulphur smell I've read about. thought I might pass out there for a second

Thanks - I had the same question after reading a kegerator conversion article in Septembers Brew Your Own magazine. They showed an airlock (as well as a thermowell) being installed on top of the kegerator. I understand that CO2 is produced, but I didn't think venting it from the fermentation chamber was necessary.
