Grow Q&A: Will Frostbite Hurt My Pot Plants?

Dear Dan, I live in Montana and I want to know what would happen to my plant if I left it out after the first frost? My buddy told me that the blast of cold weather can stress the plant into producing more THC as a defense mechanism Is this true or is my buddy full of guano? – BozemanBobby

Dear BB,
You’re friend is giving you a bum steer. Plants left outside during a frost will begin to die very quickly. Degeneration of plant matter and especially the trichomes containing THC and the other psychoactive essential oils starts immediately and any prolonged exposure to severe cold will quickly end in plant loss.

Always harvest your outdoor plants before the first frost if you can. If they’re not close to finished outside, for example some longer-flowering sativas, you’re best bet is to bring them indoors under grow lights or protect them outside with a greenhouse and perhaps a heater if necessary.
