I absolutely agree. I grow many of the species of cyclamen and figured out very quickly that it's not soil but degree of dryness, even in pots, in winter. I've had all sorts of tender species such as africanum, persicum and yes, even rolfsianum, survive to 12 degrees F because I tend to underwater in winter (in pots, mind you). The rolfsianum and others that I really worry about are also in a very quick-draining mix, although I never let them dry completely out which is a quick way to lose them.
