Coldest a plant can withstand.

Hey guys I would like to know whats the coldest it can get outside without a cannabis plant going into shock. Its suppose to get 11degrees celsius pretty soon.

I had bagseed outside through several frosts, they were fine. It depends on the genetics of your plant and observation of how she does when it gets cold. In NY state I put out some plants last year very early, like April, they survived several frosts but a few turned male. Sometimes the stress of weather can turn them hermie or male.

That is 51 degrees farenheit, they will be fine, even a fragile seedling would be fine with that. Keep in mind, most bagseed is of a mexican hybrid variety and my bagseed were fine with 32 degrees farenheit.

People grow outside in the UK!! Enough said.

It depends alot on the strain too, I have a pure indica Maziar I Sharif that is from the mountains in afghanastan and they say it can flower outside untill late Nov. Even Dec in some areas and can even withstand snow, though I wont let mine drop below 33F, just to be sure I will use a greenhouse and a heater if needed.

I had a few Alaskan Ice(WW + haze) last year to experiment with up here at 45 degrees Lat.
I was surprised it went through 6 frosts being a half sativa and all.

Had mine down to 25 degrees last January in my attic. Grew much, much, much slower but did not die.
