Cardiocrinum: from Deno back to reality

A friend and I have been doing some lily and trillium tissue culture. Early last summer, around June, we threw any decent sized lily test tubes and rooted trilliums into the fridge for a long winter’s chill.  We didn’t pull them out and repot them until some time in late March-early April.  They are mostly all up and looking pretty happy so I think giving cardiocrinums the same treatment has a reasonable shot at success.  Doing this with the plants still in test tubes does prevent rot because the environment is sterile.  You’ll need to watch the moisture level carefully so you neither rot nor dessicate your babies. If you do the fridge treatment let us know how it works out.

They spent the winter in the house under lights, and now the leaves died down - the bulbs below are intact and bigger than I thought judgeing by the tiny leaves. Outside it's late spring, so what am I supposed to do? simulate another winter in the fridge or try to put them out in the open? How much winter will they need? another 3 months and it's August, so the next growing phase may be shorter than this last one unless I give them another stay in the house?
