Advice on newly aquired Cattleya hybrid

[cluelessmidwesterner]

Yesterday at Lowes I acquired the last Better-gro bag orchid they had which had been sitting un-watered on the shelf since God was a boy. It is a Hausermann's Gala x Hausermann's Jade 'Lake View' and a very sad little thing it is. One small and two medium sized pseudo-bulbs and leaves that was also very wrinkled. (Photos later)

I soaked the crappy spent medium off last night and let it soak for a few hours after removing a good chunk of the dead roots. It does have maybe four half way viable roots (the velum firm at least). I let it dry over night and soaked it for a two hours again today. At the moment its sitting in a plastic cone pot with damp sphagnum on the bottom half and some poked around the top of the roots on a high shelf next to my downstairs humidifier.

I would like to put it into semi-hydro but without new root growth that I think would be a fool hardy. So my question is this. Should I leave it in the damp moss for humidity/hydration or soak/dry bare rooted until I see root growth? If I bare root soak how long each day/number of days a week? Or should I just bite the bullet and risk it straight away in s/h?
