I discovered rupicolous Laelias in the meantime so I've got L. milleri and L. itambana. I also got L. alaorii.

The only thing which worries me for former two is how cool (and how dry) they need to get in winter? At the moment, I keep them in pots at room temperature, just below the terrarium lights and I keep them fairly moist in a mix of sphagnum and pumice. I'll move them soon to the colder room for a few months but even there they'll get 15 C night (60 F) minimum. I plan to put them on the balcony for the summer, since they like elements so much. :)

I also got Sophronitis cernua, riograndensis and wittigiana under same conditions. They all seem to love it at the moment, growing new bulbs. I plan to give them a few cool-ish months as well (except cernua).
