How long of 12/12 triggers a plant to switch?

[Dtownhellbilly]

I have a few plants outdoors that need a couple weeks more till harvest but nights are getting cold. I want to bring them indoors but I have a few plants vegging in the only place I have set up right now. If I they go on 12/12 for a few days or a week till I get the flower room set up will it fuck up the few clones and the few plants I was going to start flower in a few weeks?

Pretty sure that 12/12 is gonna trigger reveg on your outdoor plant. If its just for 7-8 days before chop you would be better off running the flowered plants for the 18/6. Any reduction in the plants dark time for more than a few days usually triggers. Hope this helps, if it doesn't discard. TC

The vegging plants can take ambient light for a few days or more without much harm.
Shop light. Some LED bulbs. Depends how many plants.

Leave the outdoor plants out if you can keep them from freezing. Cold temps at the very end of flowing isnt always a bad thing. If you put the clones and veg plants under 12/12 for a couple weeks they will flower for sure. How cold is cold? and what have they been getting to low temps thus far?

Mid 50s day, high 30s at night next week
I was just thinking of throwing the whole room on 12/12 until I set up a ve room in the next week.

Keep the bugs in mind. The bugs on the plants outside don't mind coming indoors. Done that myself.Live to learn.
