So we have just settled into our new apartment, which is great. I have one problem though, This place stays at 70-73 degrees, we have not ran the heat at all since moving in. Thats great on the gas bill side, but looking at my carboys (empty) they are at 74-77 degrees, once fermentation would start it will rise more. any suggestions for regulating temps? i have a large cabinet that my carboys will be, no refrigerators to use, and placing them near sliding door did not help. Maybe a pic will help. I was thinking about putting some dry ice in the cabinet to chill the interior maybe?
