I was wonder if I just warmed up a fridge to 65° to 75° would it be able to keep my fermenting beer at temp or would I have to get one of those auto adjustors?
will ur fridge stay that warm? fill a bucket with water and turn temp up and give a day to see what temp its holding at. mine works great but some wont go that high.
A temperature controller would be best. A fridge is not going to hold that temperature, unless your house is 65-75 (and then why use the fridge), eventually it will equalize to the ambient air temp. Also, be aware that fermentation temperatures are quoted for the temperature of the beer, and not the ambient air temperature. The beer temp will be about 5 degrees warmer during active fermentation.
