Am wondering how hot I can get my fermentation chamber (an upright fridge with a STC-1000 control) using a paint can heater...
As for the 15 minute boil at the end. Are you at all concerned about boiling off alcohol that was produced during the lactic fermentation? Is it too little to worry about? I'm guessing it is just not an issue. Out of curiosity what were your pre and post boil gravities on this beer? I am assuming pre boil would be after lacto fermentation, when the 5 gallons went into the brew kettle...
I'll have to check my notes on the pre-post boil gravities when I get home today. I don't think there would be too much alcohol production from the souring process to worry about though.
I think your pop bottle idea would work great since they will only be in them for less than a week. Just remember to release the pressure in the daily (or more than once per day).
For the heating, why not just grab a $8 hair dryer from Walmart? Hair driers even come with a fan to lessen any temperature stratification within your chamber. If your chamber is decently insulated, you won't hear the hair drier kick on much at all.
