I brewed up a trappist recently - Sunday night. So it's been a little over 36 hours and I have yet to see a bubble. I thought maybe the swamp cooler temp is too low (64-66 ish), but I popped the lid just to take a peek. There is a good layer of white foam that I am thinking is krausen, not the foam from aerating.
Am I correct in thinking that krausen is a sign of fermentation regardless of what the airlock does?
