Yeah do try and wait at least 3 weeks, they won't degrade before that. you have a good week window once they are completely finished before the THC really degrades and turns into mostly CBD. So don't panic and try to be patient, a few minor frosts won't kill them I promise you. I've been through two frosts all ready that I had to scrape the windows on the car and still the plants are flourishing during the day time sunshine.
