Fritillaria from tissue culture

We always provide some kind of humidity tent for anything we take out of culture unless they are dormant and underground (dormant lilies and trillium). Otherwise they turn into crispy critters pretty quickly.  So we’re on top of that at least.  

I decided to plant the Fritillaria eduardii in straight pumice and put them under my grow lights inside a plastic propagator.  If they don’t kick the bucket quickly I’ll slowly decrease the humidity.  Several of them have nice roots for what it’s worth.  A few also had some leaves; I cut those off so they wouldn’t rot.  I can’t include an attachment showing their roots here but if anyone is interested I can send it privately.  Does anyone want to argue I should put them outside in my greenhouse for a winter chill?  

So what have “the Tims” tissue cultured or tried to culture? Emma and I have done lilies, trilliums, erthryoniums and jankea (not a geophyte)  with varying levels of success.  We’re also struggling to get jankea out of culture.
