Its time for me to put my cider in a secondary, but I don't have another carboy. I'm waiting on it, but if things go the way they always seem to go with me, its not going to be here for another week. Is there any harm in it staying in primary for an extra week? Or is it possible to transfer the cider to a random set of containers and clean out the first carboy, then just put it back in the original one?
Not really, the whole process takes about the same amount of time regardless of how often and when your rack.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
