well freezing is 32F. if it get's frozen it wil damage cells and cause irrepriable harm. as long as the temps don't get close to that you should be fine. keep an eye on it and look for frost. if you see some you might want to chop.

as far as when to harvest, you have to look at the trichs.

they go from clear to milky to amber. you want them to at least all be milky (or as close as possible). this will give you a cerebral, uppity high. the more that turn amber the more, couch lock stoned the high. this of course, is only as much as the strain will allow.

you can get a rough idea by the pistils colors. once they are mostly red/orangeish then look at the trichs to get solid intel to make the best decision.

also, keep in mind that when the trichs start turning amber they are "over-ripe" and THC starts to degrade rather quickly, although your buds will still put on significant weight.
