So I used to be the guy that had to fight to keep his fermentation temps down... REALLY FIGHT... swamp cooler swapping out ice bottles 2 - 3 times aday... and today I think I stalled out my lager due to it getting too cold!
So I have a heated room in my garage. I've been keeping the temp around 52dF but the temps up here dropped sub zero again and the room went down to 46dF so I cranked up the heat yesterday. I have the fermenters sitting on the floor on a piece of plywood.... I should have gotten some foam... the floor temp is 38dF... The airlocks have been slow but I haven't thought much about it... figured it's a lager it won't go crazy like an ale... so I popped the lid on one of the fermenters and it still has krausen on top, so I checked the other fermenter... yup same deal..
So what do you do. up the temp a bit? Take a gravity reading, then make that decision? Definately gotta get me some foam sheeting to set those fermenters on. Any other thoughts on how to move forward?
