Breaking Dormancy of Sinningia tubers?

I just started growing species Sinningias from seed last year, and had some nice specimens of Sinningia eumorpha bloom first year from seed. They gradually went dormant over the winter, under flourescent lights. I also have some small tubers from Sinningia nivalis that are dormant now. The tubers seem healthy. Do I remove them from the lights for a while? Just wait? Put them outside when the nights aren't nearly freezing? Any suggestions on getting them to break dormancy?

Thanks for any suggestions!
