Indoors, I like to kept them at a constant 70-79 at least until they bloom. We are having our second cold snap of the fall, lows in the mid 30s. The frost line in FL cuts across just about Orlando. North of that you do get frost, it doesn't stay around for more than a day or two and spring comes at the end of Feb. Northern visitors to FL run around in T-shirts and sandals, while the residents are in parkas and winter boots. LOL this is true, so cold is a relative term.
