Sorry for all of the questions I just want to make sure it would be worth it to make these modifications to the bag. Once you cut the hole there is no turning back.
with bag empty have got it to 35f with no ice, with a full 5 gallon of beer been able maintain 65f no problem using one 1.5l ice bottle. haven't tried see how low can get with bucket of liquid cause always been beer in bucket.
also i use plastic pail should be easier to maintain temps with glass carboy.
new thermostat giving slight probs with turning on and off, need to trouble shoot, may be mounting location might need some kind of thermal barrier between thermostat and lid of bag. but have a LBK in there right now and will be adding a 1gallon carboy all grain later today.
