my outdoor ladies aren't showing sex yet (one has very very small, hard-to-sex preflowers) in the northern midwest US. according to the website they need about 9 weeks of flowering to finish. now, granted, there will be some time that could be considered "flowering" where they haven't shown sex yet (when plants go 12/12 for instance, they don't immediately show sex), but i'm still a little worried about having to chop them early. now my question: how well does marijuana weather a frost or two? obviously a hard freeze (below 24 degrees) will kill it outright, but can it survive a few light frosts? i want to push my luck as much as possible. also, if it does get frozen, can i still harvest it the next day and dry/cure as normal or is the plant ruined? thanks for any help or answers you can provide!
