fermenting yeast look at life as a party. they party hard. this is good.
blowing out airlocks and bucket lids is not good (but not the end of the world, usually). when the blow-off hits the ceiling, this is not good.
headroom in your fermenter is good. blow-off tubes are good. fermcap-s foam inhibitor is good (and can be used in boil kettle and/or fermenter). while the yeast like (and help create) higher temps, fermentation temp control is good. this can be as simple as immersing in a swamp cooler, but having a dedicated fermentation fridge or freezer with a temp controller is very good.
