How longer?

when i grew in the colder states i would let my plants get frost once or twice. some old dude once told me it shocks the plant to make more trichs, dont know how true it is, but i never had any probs. just watch for bud rot on the more shaded buds. melting frost+moisture

Depending on how large the plant is and how long the temperature dips below freezing determines if your plant can survive frost. With an adult plant I wouldn't be too concerned about a short period of freezing temperatures at night. I would keep an eye on the plant though. As long as you harvest it when the frost kills it, you are fine.

turns out this years temps are warmer which means the first frost will probaly be later on from last years. atleast thats how its looking like for now
