2 questions please. Frost and trichomes curving?

[HowardC]

How low can the temperature get before cannabis is frost burned?
Is the curving of the trichomes shaft another indication of ripening?
Thanks

At 14c she stops growing and hybernates at 18c growth is really slowed down but grows

Yep - and curved trichome stalks are usually due to age, stress, or drying (not necessarily ripeness.) Close inspection of trichomes is a much better indicator

Frost burn is gonna occur at temps 32 and lower but when nighttime temps start dipping below 60 degrees some plants will start turning purple. I don't know if 60 is an official threshold, that's just about when I start seeing it. The purple doesn't harm the plants, it's some kind of defense with the plant's anthocyanins. The darker leaves help the plant get more energy from the winter sun.
