So I have all the equipment for a five gallon batch but my apartment sent a letter saying if they even see a propane tank you will violate your lease. So I was going to try some small biab batches in the kitchen and wanted to start with 1 gallons to see how the turn out. How big of a pot do I need for this? Also if I put in a 5 gallon Carboy will I have problems due to oxygen? Any tips would also be very much appreciated thanks guys
