I live in SoCal and our temps have been getting lower (mid 50's in my garage). As I have been banned from bringing in my primary fermentation after a bad accident, I am looking for a creative (cheap) way to ensure stable temps in the high 60's. I have left a carboy filled with water and sat in a water bath over night and in the AM, the water in the carboy has been about 59. I have seen some ideas about temp control, but was wondering if this forum could add to my knowledge. Thanks for your help.
