The cold and lack of light will slow the flower development a lot. You have autos, so try to get them as much light and warmth you can inside. Low light and no light are quite different. If your plants sit in complete darkness they will die quite quickly, but in the livingroom, I'm sure there is some light from outside, even if it's overcast. I can see your flower on the plants is quite slim and small from the cold already. In future line your auto up with your good weather so it's done before the cold and short days come. It makes life much easier and you get more reward for less effort. ;)

First of all: What’s the point of growing where it’s cold and there’s no light? Buy or build a grow box for that. No, it won’t die, but it won’t like it, it’s low °.

Yes, they will slowly die without light.

This is the readon for using fast flowering genetics or usin genetics that are adapted to climate. Give them a roof and take them out again, if they stay in your living room, there will be no progress the worst enemy of an outdoor grow is rain fro above for days- and extrem humid condtions anything else they normally can handle iam growing every year big girls outdoors, and in the end its a mix of choosing right genetics, giving them a good outdoor setup and luck my girls dont like the cold and rainy days too, but from above and the side they are save to direct rain and if the airflow fits, they can go on mine would need between 12 and 15 more days to be proper ready

They might not die, but as long as they don't get any sunlight, the development of the flowers almost completely stops.
