Can you starr seedlings in a 12/12 flower room?

I have a grow ( 1 plant ) a 2 weeks until take down. Could i start seedlings in the 12/12

yes, although not recommend

Yeah you can. If the light isnt close enough the seedling will stretch a lot though.

If it stayed in 12/12 it would grow for a few weeks until it reached maturity and then it would start to flower. Usually that means a relatively small plant.

Yes.

What would be the max amount of time before things get sketchy?
