Advice on deflasking Chiloschista please

[IWishIWasAFrog]

Hi All,

Newbie here, hope I'm on the right forum... and this is likely to be long, sorry!

Anyway, bought 2 flasks at the weekend market in Bangkok a week ago. Thought I would start off with something easy like Phalaenopsis, as growing on is a first for me... I ended up buying a flask of Cattleya and a flask of Chiloschista Viridiflora... BUT, when I startd researching the chilo's when I got back, they did not remotely resemble the adult plants that the stallholder pointed out!

The Catts are beautiful strong, healthy plants (about 50), but I am really worried about the Chilo's. There is about 50 or so plants in the flask, a tangle of roots, and some roots has started to turn yellow and translucent, if that makes sense. It was very hot on the day, about 38 C, I carried them around flat in a padded bag, but are worried that they were injured somehow.

Would you recommend:
-using a heated propagator?
-using a fungicide?
-dipping in a weakend rooting hormone solution?
-spagnum moss ok? or very fine bark?
-would it be ok to leave some agar on the roots, would not want to damage them.
-should I remove the yellow/translucent roots?

Or should I stop worrying and just get on with it!

Any advice on deflasking would be much appreciated!
