Cattleya araguaiensis deflasking

This is my first attempt at deflasking cattleya genus. As if it wasn't challenging enough, I have pretty bad experience with this particular species - Cattleya araguaiensis. I tried it back in 2012: one try, another try - but every one of them eventually died...
Maybe I was getting weak plants?
Now in flask with over 25 seedlings there should be at least one that is vigorous enough to grow nicely despite my care... That's my hope.



Flask came from Ching Hua orchid nursery.



Plantlets are on the slim side but have pretty long roots, that are much more flexible than brittle roots of paphs that I got used to. Agar was soft and came off very easy.



Deflasking cattleya for the first time I wasn't sure which mix and pots should I use for my araguaiensis seedlings. My old cattleyas grow in coconut husk chips, but seedlings probably require more moisture-retaining media. After much of debate with myself I decided to experiment with two mixes: sphagnum moss and mix of small coconut husk chips and sponge rock(perlite).



For sphagnum I used one net pot and one small shallow plastic tray with holes at the bottom(they work good for paph seedlings).
For coco mix - just plastic trays. Net pots are good for seedlings because they provide fast drying, but in the long run they pose the problem - roots tend to stick out in the holes and tangle within the net, so I don't really like compots in the net pots because you do need to repot compots eventually and will end up breaking those tangled roots... That's why I did only one net pot compot.

Here is the outcome : 4 pots with 6 seedlings in each.



They live in the smaller tank that is warm and humid.
