Plants inside with no lights???

[Tomatovator]

My plants have been in the garage for weeks either under fluorescent lights or in a south facing window. They are about 5" tall. The next couple or three days are going to be cold with highs in the 50's and lows in the 30's. Can I bring the plants inside for 2 or 3 days without bringing in the lights? I really don't have a good south facing window in the house but they would get ambient light from a east or west facing window while they were inside.
