Hi there - I plan on brewing a Chinook IPA but my apt stays a toasty 80 all day b/c my wife thinks the a/c is going to freeze my newborn. I know a swamp cooler will solve the problem, but we're going away for 3 days over July 4th and I'm worried about the temps getting too hot. Would loading up the tub with several frozen 2L bottles do the trick and keep the water surrounding the fermentor in the 60's for the 3 days? Since this would occur from days 7-9 in the primary, would it be ok it I temporarily plunged the temps to however cold i can get it (40's???) and hope it doesn't get above 70 before I get home? Any help would be appreciated.
