Zu kalt

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. ;)

You can move them out in the day time and in at night if its to cold. Day time temps should still be fine, But if they are not. A south facing window. as much light as you can give them. If they are Photoeriods the main thing is you want to be giving them aorund 12 hrs of uninterrupted darkness so they can flower, and any light in their dark time can mess them up. this included going into the kitchen for a drink of water, flash lights can mess them up, nightlights or street lamps. Autoflowers don't matter, you can have them under light 24hrs a day and they flower. not advised but it can happen.

Zunächst einmal: Welchen Zweck hat es, dort zu wachsen, wo es kalt und kein Licht ist? Kaufen oder bauen Sie eine Growbox dafür. Nein, sie wird nicht sterben, aber es wird ihr nicht gefallen, es ist niedrig °.

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

Sterben vielleicht nicht aber solange die keine Sonne abbekommen stellt sich die Entwicklung der Blüten fast komplett
