She is still doing well, no damage yet, from what I see no rot as well.

My step ladder wont go all the way to the top of the plant, but from what I can see from the ground she looks good..

I should be able to push her further "they are calling for a fairly warm week, just cold overnight"

Ontario weather is looking bleak tho, they are calling for an early/harsh winter this year.. These Sativa's are just not suited for Zone 5b, but Im going to try lol.

I've grown at 7000 feet elevation. Temp swings from 28 at night to over 90 in the afternoon. As long as you don't get a "hard freeze" (below about 26) you should be ok. The plants wont like it and their growth will slow way down, but cannabis is a hardy plant. If you get damage, remove it ASAP, as that's where rot will start.

I have had 3 hard freezes this year already, with temps going down to -8c "17F" and shes still going..

5 heavy frosts so far she has been through and still standing..

This "1 frost kills them" is BS. Try 5 HARD frosts and still standing.

This morning's round of frost is gnarly, winter is quickly coming.. I am pushing this Sativa further tho, she's not ready yet

I've had plant's in the ground into week 2 of November here by Lake Michigan. Multiple frosts and light snow. Some of the most beautiful flowers I have ever seen.

I worry more about freeze warnings and rain this late in the grow. One good rain in the 40s and no wind can really fuck everything up.

First frost kills them

Bullshit. Absolute bullshit.

Bullshit. Absolute bullshit.

Think about what it’s doing to your plant. Your plant needs to use stored energy during dark periods to grow flowers. If it’s struggling to stay alive each night, cells rupturing and in constant state of repair, you may as well kill it as it’s already dying, and has no purpose left
