Nice. Most of my close ones are already down. I've got three more rounds of late season stuff that is from 4 weeks into flower to just breaking dirt this morning. Those last ones will be New Year's bud {if all goes well}.
I love New Years bud ;). Getting the shed going in a couple of weeks.

the first frost of the year was on sunday night, i checked my pumpkin patch today - tuesday - and everything seemed fine. the temperature dropped to -1*c so it wasn't a hard freeze - the weather network also posted a frost warning. the only difference i found was that top colas were 'browned' and withered a bit but the rest of the plant parts (colas underneath, leaves, stems, roots etc..) seemed intact.

here are two photos of the top cola of one of the plants. the first one is from friday (before the frost) and the next one is from tuesday (2 days after the frost).

hope it helps as i had no idea what to expect as well...

So I have a question, I live in SoCal and we don't really have a winter were it freezes. The coldest it gets is about 45-50°f at night USUALLY and 60-80°f during daytime USUALLY. I've been vegging my plants under a T5 for a month and a half and last week put my plants outside for a winter harvest. They should all be done by xmas since they are all Indica dominate. Will they be ok and grow to there full potential. I usually grow outdoors but in the spring into fall. Any advice will be appreciated. They are getting 7 hours of direct sunlight and about 12 or 13 hours of daytime.

You’ll be fine

Thanks, I was wondering bc when i go out in the morning there is mad morning dew on the plant and wasnt sure if it would cause bud rot due to the cooling weather

Three tricks to combat frost. One requires electricity.
Wet the soil around you garden if there is a risk of frost. Dry ground is more frost prone than heavily moistened ground.
Use hoops of pvc and poly if possible.
And this one is used in commercial agro anytime frost is forecasted
Use fans! Moving air prevents frost from forming. This is obviously an issue for most exterior growers.

Funny you say poly hoops, I'm a hula hooper and use poly and hpde to make mine. Might try this with a bare hoop I'm not using !

I use pvc tubing that is cheap and bends well. I hammer 3 foot lengths of rebar into the ground and slip the tubing over them. Cover with poly either clear or opaque and weigh the edges down with dirt. Simple and quick. If the weather improves I remove the plastic for better air flow. I think it’s better uncovered if possible.

These girls hit 27°f inside of my hoop-house the first day of summer (june 21).they were all laying flat that morning. I was too disgusted to take a pic. But they are doing hot!! Crazy year here in the SW

yo, so last night was a dick. My 5 to 6 foot tall R2 plants are 8weeks old yesterday. filly finished. frost hit like a motherfucker last night and they were silly frosted this morning when i walked out to cut them....
sup?
i have never had frost hit a plant like this. Is the bud quality going to suffer?
does this negatively affect the trichomes that were present already? like do they freeze and break off like on dried herb?

Hey all, saw the comments about getaway mountain, has anyone grown out their gear and actually had them tested in a legal state? (e.g. early finish is nice, but how strong are they? Brain twister seems good for example :) ) I've been spoiled by the last few falls in my northern lat and have gotten into the habit of growing ridiculously long flowering sativas that prefer to be cut around election day. This year with pretty much consistently 20deg below average temps mother nature has gotten back at me the low around 6am on sunday morning will be *24F*. I could add a plastic sheet draped across to cover them and run heated home air out of the window that's up against the garden, but as all of my girls are 11-13 feet tall stuffed in an ~200sqft fenced area off the house and I can't fly, that's not really easily done... (could throw a 2x4 onto the house just above or below the second story window then wrap sheeting around it that then drapes across is the best I can do, but that's far and away not fully enclosed.) So I'm planning on cutting them 3-ish weeks early tomorrow (Pout!) They're pretty damn protected from the sides.... so I'm still toying with finding a huge tarp and tossing that on top of them and hoping for the best, but.... well, it's better to have an early harvest (all trics are milky that I've been able to see, so at the least they'll be nice head highs) than to have a ruined harvest... Anyone want to try to convince me that adding a tarp/covering and piping house air into a mostly open garden will be enough to counter an hour or so of 24F weather (they've been fine to 30F at least so far...) Edit: just smoked some of the plant (red headed stranger x indiana bubble gum which I now call redneck bubble gum) I took down on the 11th, to give the girl next to it some extra light / test the high. I'm fairly happy with it so I think I'll be fine if not thrilled by removing (at least) all of these the tops and drying them tomorrow... Though obsessively looking at the weather channel, it looks like aside from the low of now 25F, the weather seems fine for the next 10 days... I might push it, and immediately harvest if anything looks dead on the branch... the ground won't freeze yet (and I can water with warm water) so my only concerns are the buds... (edit #2: decided that cutting the tops would be the worst case scenario as it would expose the main stems to the full effect of the cold. So I added 3" of mulch and will water with ~ 80F molasses water before the low hits then will check the plants for signs of death, my thoughts are that if it does die, I'll catch it w/n 12 hours which is not really any different than trimming them, or worst case scenario, any worse than trimming them after they've dried as some do. Will update with my results in a new post come actual harvest.)
Yo, i just heard about getaway myself in a thread about the origin of a sativa dominant old world strain called R2. (highly debated topic) We know getaway mountain didn't create the R2 strain but is using it in a lot of crosses. My R2xSkunk was a 10" clone on june 7 planted in the bare earth, not fertilized. no ph adjustment, and by july 24th or 25th it was 5'7" tall and entering bloom. I hit 8 weeks yesterday and it's fully ripe. frost raped it last night unfortunately which is why i am on this thread but i'm optimistic it will be ok. R2 is mad cold tolerant.

What state are you in or province?
I'm in Canada Ontario and go do im so worried some of my plants won't be ready until frost

I'm glad they are okay

Right now it's 20-25c in the day an 16c at night
Yea Im still a bit worried but they are more hardy than I though. Scoped today and still need some time. Sour Sorbet is the closest.20190921_111947.jpg I am in Southern Vt we got lucky and temps have gone way up.

We had our second frost near North Bay, Ontario today. This time I had tents over them at least. They survived the first frost uncovered, but killed some leaves and caused stunted growth. Our weather is quickly going to shit, highs of 10 and lows of 1, usually a low of 1 is -2. Not sure what to do, three of my plants are not even close to done and they are the biggest ones. Would hate to lose them.

Worst case Ontario I could cut this one.

Don't want to lose this one either since it still needs a couple weeks.

But my monster beauty is only this far in as of today with weeks to go yet.

I have covered the plants with tents which I have been doing since it rained almost all of last week and a wind storm tore down almost a whole plant.

Can they survive just being covered from the top like this based on our weather posted below? If not, how can you keep them warmer?
