Hey folks, I want/need a ferm chamber. I have seen so many versions of DIY chambers that I'm drooling from confusion. I would like to do the following. Buy a chest freezer, a temp controller and go to town. Is it really that simple? Since it is summer here cooling is my goal but eventually warming up would be needed. How would that work? Sorry for the long winded story here but I have no knowledge in this area. Help a brewer out!!!
