>>You may have higher level of fusel alcohols and diacetyl, I would keep temps. down as possible until last few days of fermentation. They raise temperature to 70 so yeast can clean by themself (including re-absorption of diacetyl).
I don't think Diacetyl will be a problem, but Acetaldehyde might.
I think the yeast may reabsorb some Acetaldehyde.
You are stuck with any Fusel alcohol.
>>I brew in my garage and don't use a swamp cooler.. I know I should really invest in a fermentation chamber just haven't had the time or the money to do so.... I've read that people put a wet towel around the carboy... I think it might be too late? Today will be the 5th day of fermenting
I made a swamp cooler, inspired by Yoopers
You wait until these types of coolers are on sale (I got a 110 can for $44 shipped).
Its a @#$%^ inch and a half not deep enough due to the slant of the wheel well housing, so I bought a 8'x2'x1" styrofoam insulation slab, and madea DIY cover that can house a pale. If you use a car boy, all you need to do is make a simple styrofoam cover like Yooper did.
I also use this cooler to hold ice water which I pump throgh my immersion chiller to cool the wort that last 15 degrees in summer.
