Doing my first hef tomorrow and am worried about not having a blow off tube. I don't have a tube that fits the head of my plastic carboy. However this is a 5 gallon batch in a 7 gallon carboy. Am I going to be okay?
 
Yes your going to be fine. Take a hand towel, dip it in starsan mix, wring it out, put it over the top of the carboy. You only have to worry about air getting in. Once fermentation begins, the CO2 coming out of the carboy will keep the air out, just keep it covered lightly.
 
Good temperature control of the fermentation will reduce the risk of excessive krausen height development during the first few days.
