Should I pull girls because of cold weather?

I've got a couple of Lady's out in the sun but my concern is that the temps are about to go into the 30's and the lady's are still in their 4 week of budding! What should I do? Pull them or wait till the first freeze? or are they being effected by the cold already?

cannabis can live even when temps are around freezing, BUUUT I wouldn't recommend leaving them too long in that kind of weather. You might get some purple buds tho

leave them as long as possible. You do NOT want to transplant a budding girl. If you think it is going to frost, cover them with trash bags overnight.
