how to over winter ginger plants

Hello I have two ginger plants that seem to only have gotten really nice now end of summer. They are outdoors by a wall west facing.
How can I overwinter them?
Put them in a pot .
We have VERY linked south facing windows already super crowded with the usual safe keeping of other plants.
We have two basement east facing window that get not much light but we use additional LED to supplement.
We also have an unheated 96sq feet greenhouse where I have a big 45sq feet elevated planter box facing south sun half the day (tree shade the other half) with one foot deep soil where I sink my fuchsia pots and other fragile flowering perennials. It's usual over zero unless we have a terribly cold winter snaps like last year. All our fuchsia froze.
Just would like to know will the ginger make it out of it not worth while to try save them.
Thank you for you usual help dear gardening specialist we are in North Burnaby Vancouver.
