Storing Sinningia tubers?

I recently bought a sinningia that went dormant as soon as it arrived. How do I store the tuber so it doesn't rot? Any and all help is appreciated ^_^

put it a paper bag with a little bit of vermiculite or pearlite & put it where it is dark all the time, then check it in a week or 2
