I have been reading the forums since receiving my LBK for Christmas 2014 and have not seen an answer to my question. I have seen solutions to lower the temperature of the LBK, but not how to raise the temperature to the proper fermentation range. My basement stays cool year round. The first beer and first cider were fermented just below the range, which did not create the best. My second beer started off too cool while I was on vacation. After the first week, I placed the LBK in a cooler with a half gallon milk jug full of water. I microwave the water and have raised the LBL to 64 - 68. Unfortunately, I need to do this once or twice a day. Are there any other ways to raise the temperature? Since the first week was below the temperature and no or very little fermentation took place, should I start my 3 week period when fermentation started?
