Hops started on the garage

I grew cascade hops last year in pots. Had a decent first year harvest. I moved the pots inside for the winter into the garage. When cleaning out the garage today I noticed that one of the pots had sprouted vines at least 3 feet long. The vines are very pale green, almost yellow/white. I moved them outside tonight. We are not expecting frost anytime soon so it bought it would be safe. Should I cut them back and wait for better vines? Thanks.

No, they will green up and fill out now that they have sun.
