FROST: general rules from experience....

Hmmm.. sounds like you're a Northern MN grower. I [ahem] sorta know a person in a similar zone who is also presently seeing temps in the 29-30 degree range. We covered our outdoor, in-ground plants the last couple nites.. tonite especially! Didn't get out there until just now, in fact.. 10:30 PM Central.. 29 degrees F. First time I've seen what looks like minor damage to sun leaves. Plants were frosty and felt mildly crusty/frozen. I'm hopeful they'll bounce back.. we're supposed to see some sun tomorrow. Regardless, I'll check in and let you know what I find. I'm eager to keep this conversation going. As an outdoor grower in the far, far North, it's helpful to know my limitations!
Hey, ya got it right . . . . 630am & radio says it's 25 . . . ouch!!
my temp here says 26-27
I'll uncover about 830-9am
From what I can see on the weather front it's Indian summer for the next 3 weeks . . .
Sure hope so . . .

Tis the season. I'm up in Canada, prairie province, continental climate. Had a brutal frost a few weeks ago, got down to -5C (23F). I managed to cover one of my plants, but couldn't cover them all. I came out the next morning and I was sure the plants were dead. Leaves were frozen solid. Had sunny hot weather the next day, and long story short they seem to be OK. Tomatoes dead, Corn Dead, Beans Dead, Squash dead, but my "CBD Critical Mass" are still growing strong. The colas lost their white pistils and overall they have a more purplish look to them(leaves still green), but they appear to be continuing to grow and ripen. Had 2 plants still in veg and there isn't any noticeable damage.

Still curious about any potential positive effects of frost. Didn't notice any "shock" into budding on the veg plants. Some of the uncovered colas have amber trichomes, covered cola trichomes are all milky or clear. The amber trichomes are likely evidence of frost damage rather than faster ripening...

We also have some pretty extreme diurnal temperature fluctuation(difference in temp between day and night) this time of year. In fruit(apples, grapes, strawberries) diurnal temperature fluctuation causes more sugars to accumulate, it makes fruit sweeter. I wonder if diurnal temp fluctuation has any effect on bud quality....
Good points. I wonder too if the amber trichs are indicative of frost damage. I grow in a desert, veganically. I don't spray anything or have pests. So we have those warm, sunny days and cool nights. 88 to 48. 38 the other night. Be interesting to have a scientist experiment.
About ten years ago a neighbor left a plant out until it was snowed on and claimed it didn't hurt it. I think he said, "it's alright". Even he didn't seem convinced. I couldn't try it as he has no idea I grow or toke.

Uncovered plants about 9 AM this morning.. still frosty n semi-frozen from overnite. Anyway, they seem fully recovered! Phew!! My thermometer says we maxed out at about 28 degrees last nite (in terms of the low in my neck of the woods). Hoping for a warm up here too!

Well it's Tuesday, 9p.m. & it's 65 degrees here. 2 of my girls sure didnt like the cold. The plants turned purple and the pistelets hairs are black . . . just reeks the smell & leggier than all get out. So ever since that first frost a couple of weeks back, I haven't seen no bud growth, turned purple, & black pistelets . . . this is bagged seed. Got plants in the ground right next to them 2, and she's green, big buds, with pistelets growing more rust color every day. Will probably start chopping soon. This Wed & next Wed the temps are in mid 30s, with 75 forecasted for Friday. I'm pretty sure the cold turned them plants purple . . . I don't know about the black pistelets, never seen that before. No mold nor rot. Got plenty of ladybugs, wasps with marigolds planted nearby. Good airflow. Black pistelets

Well, I'm pretty sure I was over-watering- nuets. Went back thru my notes & that middle plant seemed or had an over water episode earlier . . . been monitoring the last cple days here & with the high winds helping to dry here out, she looks better today, happier. Her pistelets aren't so dark - black. Supposed to be 38 - 40 tonight, still windy, so No coverings.

HELP PLEASE!!
I got 2 days to decide, then COLD hits
I got 1 plant that I can take cause she's ready. However, got 2 more, that need a cple more weeks. So, can I Dig-up those 2 and bring them into garage?? If someone would have an idea of how wide their roots spread, I'm hoping I could capture ALL . . .
Am I desperate or WHAT??
Someone else just had to try THIS??

Never tried it and don't think I would. You won't get all the roots but it might live for a while. I would shelter them where they're at if possible.

I would BUT the temps at night will be around 25 and the highs will only be in the 40's from Wensday on . . . with rain snow & wind. These plants were all planted at same time . . . from bagged seed. The 2 I'd like to dig up are the ones that turned purple.
Dang, okay thanks for the comeback.

Gotcha. That's a tough one.

I've never had frost kill a plant and I tend to leave them alone to ripen, weather or no. That's because, in most places, there will be one or two light frosts (like I just had) and then a clear spell, during which the plants will quickly ripen. I've lost a lot of leaves from these weather dips. The buds are fine, though. I guess it'll just make trimming easier :)
I agree I’ve been growing for probably 10 years not a pro just a New Yorker who loves smoking pot we have not had a huge frost yet but the rule of thumb where I live is after the second major frost chop em. We have had a couple little frosted but nothing major. I’m growing agent orange this year which is a Sativa dominant strain and they seem to do well even after heavy frost 25 degrees and lower if the sun comes out they bounce right back can’t wait to post pics on here happy croptober by the way to everyone and I hope the bugs didn’t hurt anyone’s crops this year. I had a major aphid problem but some dawn dish soap and a lil oil took right care of it. Probably got another couple weeks till bud is fully done will post pics before I chop it. Most recent photos

Well, sad day . . . the 3 outdoor gals got "choptorber" @ 5am. My reads suggested that chopping before daylight & taking before rain - drenched to help the drying . . .
The gals are hanging out now, put a fan below for an hour . . . keep hearing a long dry is beneficial, so "HOW" should I schedule their "fan priveligous"??
AND, yes I'm smoking ;-)

This has been a very unusual fall so far here in the Ottawa Valley area in Eastern Ontario. This is not considered a warmer part of Canada for sure lol, but we still have tomatoes and peppers fruiting in the backyard without a sign of frost locally on anything. I still have the weed outside too and they can be harvested any time now (all for bubble hash). I really lucked out with PM and bud rot too. The zucchini plants didn't even show PM this year, and that's like a miracle.

I won't fool myself though. Winter is coming!

What's the temperature and RH where you have your hanging plants? You should always have a fan going for air circulation, just not pointed so that it blows directly on your bud. Watch your biggest colas for mold everyday because this is your greatest danger right now. The mold will often start under the budlets making up the colas first, so check there.

I'm old school with the humidity readings. I go by . . . yup feelings LOL❗ Anyway, with that said, I turned all fans off after first hour of hanging. I go by feel of plant . . . if she's drying to fast, I'll hang wet wash clothes - towels in or outside of hanging room. Ya got to monitor how fast these towels dry, should take a Gd day to dry. If she's still pretty wet after a day, too much moisture . . .
So far, she's on a slow roll of drying. As she's hanging I'm doing daily trimming. Yesterday I cut some branches & introduced them to a paper bag to gauge moisture . . .
AND when I checked the bag this morning she's pretty wet yet. I think she'll hang a Gd 10 days plus.
Really old school here . . . anytime I roast a Turkey OR other meats, I use a brown paper bag . . . I'll put my Turkey in a 9×13 pan, throw some bacon on top, a little seasoning, nothing else & slip the paper bag over, tape shut & put in oven @ 325 - 350 for 5 hours.
You can peak at 4 1/2 hours.
YUP, paper bags folks, don't cost ya a thing.
Gotta say, she's Gd smoke ;-)

Here's exactly what I did; days before chopping, trimmed all big fan leaves, chopped the 3 outdoor plants @ 5am. brought in & put two less bushy plants in one room & other fuller one alone. Put fans on both dark rooms for a cple hours to dry dew. Shut doors. Return in a cple hrs, smell & feel. These plants will make their own humidity as they dry . . . too much, leave doors open.
Not enough, close for a bit . . . much like curing, ya got to burb the slow drys . .
I'll cut off a stem & hang with the 2 to see how fast she drys . . . & compare to the one in the other room. I've noticed both rooms are drying different.
I live in a patio style A frame, w/loft, no basement, with Slate stone heated floors. I have not turned on the heated floors . . .
So it's cool in here . . . last night I turned on a infrared heater & opened both doors . . .
I need or want to keep temp about around 60. I'm hesitant to turn on the floors . . .

Rain picked up this week but no freezing temps except one night so letting them ride until next week. I can't believe I'm harvesting at the end of Oct at more than latitude 60. Strange year. I only harvested one this year that I hadn't done anything to for a while (was hard to get to) and since I hadn't treated with keefir I lost 50% to pm though they were the nicest buds. Last keefir treatment tomorrow. Girls are gonna be fine I hope. As I was throwing pm buds in the trash yesterday tears came to my eyes :D

I have two sativa taking there sweet time out in my hoop house not looking very happy. I sealed it up the best i could and put a ceramic heater in there but temps dip just below freezing these last couple nights. It is 9F outside and snowing now but 34f in my hoop house 63%RH.Its supposed to be pretty mild next week so Im just trying to making it a few more days like this.
I already harvested one really nice plant(3.5lbs) but i would love to get a decent pull off of the other 2 plants i have that were about the same size for some variety. They look like they need another 3-4 weeks, I hope they get a move on

My guess is you had a plant hermie slightly or maybe the pollen traveled a long way? You might find more though.(:
