Not really. We do have a garage but it is not frost free, it is a bit of a mess so things go in never to be found again and the mice will find anything edible. I have put them against the glass so it will not be very warm, and will source a black plastic bag to keep them dark.
Might try a couple in the fridge. If I dip the roots into a solution of aloe vera first it might keep the fungi at bay. At least in the fridge they will be neither too hot or too cold.
