Dendrobium tannii 'Dark Pink', what to pot in

[wdfish]

Hi. I joined the Orchid Board back in 2016 but never posted. I've been growing orchids for many years -- mostly Cattleya hybrids, Australian Dendrobium, Cymbidium, I'm in Southern California and grow outside and in a shadehouse. I just acquired Dendrobium tannii. It's bare root but will never survive here (bare root and without a greenhouse). I need to know if it will thrive in a medium and if so, what? bark? moss? Does it need to be in a greenhouse? warm or cool growing? Will it grow in a shadehouse where winters are mild and summers can get to 110? Appreciate any help.
