remember when your fermenting inside a keezer/fridge the offgases have nowhere to go and remain inside the container at full strength. as HB99 stated the best way is baking soda for the smell and rid-x for the moisture from the fermentation.
do you need to give the keg a blast of co2 while doing this?
I, for right now dont have my co2 tank, but was planning on trying to lager in my cornie because my carboy wont fit in the fridge, but the cornie will.
