I had to pull up my brussel sprout plants since it was about 10 wind
chill here close to St. Louis. I dug 6 up with roots. Now they are
in my basement with a florescent light. The sprouts are about 1/2 to
3/4 mature. Can I get them to keep growing or should I just harvest
them now? Educate me. Thanks Joe Mc

What was the actual temperature?
Wind chill temperature means nothing to plants. No matter how strong
the wind blows, the temperature of the air outside does not change. If
the air temperature is above 0ºC (32ºF), plants will not freeze.
In addition, Brussels' sprouts can withstand frost, in fact, most
growers feel they only achieve their finest flavour after a couple of
frosts.
In your case, since Brussels' sprouts are fairly high water users, I
think you'll be hard pressed to keep them growing now that you've
disturbed the root system. IMO, you might as well harvest them now
before they start to wither and dry out in your relatively warm and
dry basement.
