WNY here, frost risk is supposed to be over in a few days....if ya believe any of that shit...i got a 20" tall girl i want to put in the ground ASAP but my inclination is to wait until at least the 21st of the month. With our luck here the forecast will say no frost then i wake up and she's dead

I’m putting mine out on the weekend, I don’t want to pot up again. Lows in the 8-9C range so should be good lol.

Planted 13 yesterday. Fingers crossed but thinking I’ll be ok. The forecast for eastern Ontario looks good. I’ll try and get another 10 in before June.

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
I just got this batch of clones and put them into my first DWC setup,, They are showing weird signs in the very middle of the plant where the main cola is going to grow. I am not sure if this is just some weird thing the person who gave me the clones did during his cloning process, or if there is something wrong with my DWC.. Im using Fox Farm trio so ive started with just the big bloom and a smallll amount of grow big, about 285-300 ppm, 5.8-6 PH, 68-70 degrees in the water, and I used some Great white and KLM root strengthening to help with the transplant. theyve been in the DWC for a little over 36 hours now.
Have you any experienced thoughts to share?ComfortCreator

Not an outdoor grower but a basic question as knowledge is good....I know the plant will die if frozen of course, but if you were right at harvest and the plants froze, would it affect a ready to harvest result?
Huge sympathy and support from me to those dealing with outdoor environments. You folks still grow the best sxxx imo when done right! Sun

Personally I dont wait till it frosts. Simply because as the tricomes freeze it dont take much for them to degrade and fall of the plant. I may be wrong but personally I really like what I get out of it even tho the buds dont get as big because the plant doesn't think its dying to push all its energy out. But it's like most things personal preference.

this is my 2019 run. Sept18 it frosted hard enough to kill all my squash. Here is the morning of the 19th frozen before harvest, and a bud shot up close showing the trich coat. This was still super sticky dank after this freeze event
