I wintered mine in my garage in BIG pots and they all pretty ran bines that were 3-4 feet long. White too as they were in the dark most of the time. When I took them outside these white bines died in a couple days. This was 6 weeks ago. three of the five have multiple bines growing tall over 6 foot and full 6 twines each pot. The centential is slowly coming along, slowly. The golden didn't make it, replaced it.
You should be OK.
