temps

Will 39 degree outside hurt my flowering plants.

Yeah that's well to cold you in the uk?
You need to be at minimum about 65-70

it hasnt hurt mine yet. but i do think thats pretty cold, i was told that my plants could possibly handle a light frost.?.?

Well I've never read that it can handle frost! Cold weather and canabis are never a good combo
I done and outdoor plant last winter and snow fell and with in hours of snow my plant was fucked

No. I've had mine as low as 19-F in the grow room. They can take the cold. They just can't take it for a long period of time.

Healthy, mature cannabis that has been growing outdoors for most of its life can handle 39 F. That stuff about having to be at 65-70 minimum is utter nonsense.

I am east of the mississippi river and it is supposed to get to 39 degrees for two nights. Thank you for all your help. Shoul I bring them inside for those two nights

How long have they been growing outdoors? If you just put the pots outdoors very recently then bring them in if it makes you feel better. But if you have been growing outside 24/7 for at least the last few weeks then they are fine.

Its mostly large & FAST drops in temp that will mess your plants up. If the temps have been slowly dropping and the plants dont show signs of stress you should be ok.
its by no means ideal though.

& was it a sudden or gradual drop from normal temps?

Leave them out there. The plants will start to get hardened off for even colder temps.
There benefits of cold. bud colors, bud density, aroma.
Your doing a good job, keep an eye on the night time temps. try and put them in places that won't frost easily when temps get even colder.

I would put some plant plastic around your pots when temps get even colder. keeping your soil warm is very important. When your soil gets cold it makes the roots cold and the plant slows down growth.

December in the flower room. Lights off, Yes they were hardened off for cold. around 5-6 hours exposure. I think it was almost -20F outside that day.
it's important to leave your stuff out side when it's just 39F

My girls and I thank you for all of your help. Very thankful for the advice.
