Should I be worried? Are they all going to be dead in a week? I didn't know it would get so cold and left a fan on while the lights were out. I guess it was freezing temps in there for about 8 hours

I just want to know if marijuana plants will continue to live if put in freezing conditions for just one night. Is it too late? Only time will tell?

They are fine most likely. It mainly depends how quick they warmed up and how cool the root zone got.

How big they are to. Expect to lose some fan leaves. Might get some colors.

I don't think I see any sort of damage done. Not sure what to even look for. I also just did a lot of bending a few days ago so they all still look a bit bent out of shape.
they been vegging for I'm guessing about 5-6 months now
just checked, temps are now up to 36 degrees and lights come on in less than 2 hours

At 28 deg, the plants will be just fine, for about a week. At this point they will die very quickly and not much suffering ...

I dont grow in a house , i own a beat down commercial building i use for the grow & the old furnace went out in mid winter & was out for 3 days before i found out , when i visited the grow to top off the rez's & check ph i could see my breath , i popped a propane salamander heater & a few electric heaters in the building to keep it warm till i could buy a new furnace .

The plants that were closest to harvest were fine where as the clones just put in the table were dead as hell , i had some plants get stunted growth as well but were talking 3 days vs the 8 hours your plants got cold , i'd bet they'll be fine .
