No sure what you mean by this. Do you not have an air lock/blow off tube on your bucket lid/carboy normally? Are you letting it release CO2 while still protecting it from "wild things" falling in? You may have heard to not put on an airlock until after the krausen falls because you might use a blow off tube up until that point, but either way you have to use one or the other.
As for the difference between pail and carboy for primary...well there are some differences, but I thought you said you couldn't fit your pail in the mini-fridge? You do have to primary ferment at around 50F which would likely require you to use your refridgerator regardless of what you're fermenting it in as a primary or secondary.
