Is my thinking correct. I have a 2 stage controller. Freezer is in hot garage so I don't need heating device. Would I set the first stage to cooling 65 with a 2 diff. Then set second stage to cooling 62 with a 2 diff? If I wanted to ferment at 65. Is that too tight of a range. Thanks for help. I know this is a silly question. I just wanna make it right so I can use it for the first time tomorrow.
