I have two plants going outdoors right now. They were from seeds that fell out last year and have been outside the whole winter and popped out on their own. I noticed the first in mid february, and the second about two weeks ago. They are growing, but very, very slowly. Been through lots of cold weather, and are mostly fine other than the slow growth. If you have extra seeds and want to experiment, i say go for it.So this whole thread is about harvest season.
What about planting season?
Whats the earliest you can put an indoor started plant outdoors?
Is a single frost going to kill a cannabis seedling? What about a plant on its second or third set of leaves?
If you are past the threat of your last frost are you good to plant? even if there will be cold nights that hover just above freezing?

A seedling if hit by a hard frost can potentially die...vs a well established plant at harvest.So this whole thread is about harvest season.

It’s been the same here with two frosts but not a deep frost hovering around 32. My plants still in the ground are doing fine. But taking them down tomorrow due to the rain that’s coming ...... bud rot is a real possibility now .Here in the north i had a frost on two nights back to back followed by mild sunny days 70 to 75 plants in containers on a deck survived fairly some of the leaves turned yellow and curled up the turned brown trimmed them off and plants seem to be doing well now.Buds still look amazing. My plants in the ground right next to the deck, were not affected by the frost whatsoever, flourishing still. A matter of week or so before next frost is expected to hit will probably pull the container plants before then.
Lots of strains of cannabis can handle a pretty strong frost. I've had plants handle frosts as low as 28 degrees F without killing the plant.
Things to consider, some strains are more sensitive to frost than others, if they are in pots this can make them more sensitive.
Sativa strains tend to be more sensitive to frost than Indicas. Indicas and Indica dominant hybrids are capable of handling frosts as low as 28F. but there have been reports of sativas handling frosts just as well.
I'll leave this sticky open to discussion for other experienced users to post their experiences, I will compile it into this. I felt this was needed as this question gets asked a lot when a frost comes by.
you can protect the plants if they are of manageable size or if you are handy enough to build a sturdy setup.
this can be as basic as a pvc greenhouse with plastic wrapped around, or even sheets if properly secured to not touch the plants... or as large as a full car port with greenhouse grade plastic secured.
how much the temperature rises the next day also tends to define how the plant deals with the frost. if it frosts and it rises up to 65 degrees+ with sun in the daytime, the plant is much more likely to take the frost and keep growing vs a plant that takes a hard frost and sees a 45 degree day with clouds....
cooler temperatures (55-40 degrees F) will definitely bring out some purpling in some strains, and cause flowering to speed up, nights that dip into the 35F zone boost this even more, bringing out even more color.
sorry for the organization of this thread, guess I'm too much of a stoner after all

Here is my greenhouse. It may not be pretty but it is extremely effective. Plants are dry and warm with a space heater available for the cold nights.
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....
Yes, that's what I saw in mine. Temp is supposed to hit 29 tonight. So I'll have them covered. My tomatoes & peppers didn't survive frost from 2 days ago . . .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...
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!Yes, that's what I saw in mine. Temp is supposed to hit 29 tonight. So I'll have them covered. My tomatoes & peppers didn't survive frost from 2 days ago . . .
After tonight it's supposed to warm up, might even see 75!! If I can only keep em cooking a while longer!?
