Need Strategy to Keep Fermentation Temp in Basement

Hi everyone,

I need to start keeping my fermentation in the basement.  I live in Michigan, my basement stays around 65deg now, but it will get much colder in the upcoming months.  I’m not sure how much the temp swings as of yet.

I brew only ales right now.

I was wondering if anyone could point me in the right direction to keep proper temp.  My basement is unfinished, so I have many options.

I was thinking about the electric fermenter wraps with a controller, and/or making myself an insulated chest-type container to help hold temp.

Thanks in advance.
