Was think of building a simple, insulated box to slide over my 5 gal fermentation bucket. I want to hook up 2 pipes and 2 fans, 1 in and 1 out, to My keezer. I could use a probe and pid to control the fans.
How stable will this be temperature wise?
Will the air movement cause any issues with the keezer?
I mostly want a ferm chamber for lagering in the 50's and keeping my ale's in the 60s in the warmer months.
