One thing I noticed is that the others all seem to be in a bark based mix. That is more typical for many growers.
You should be very careful with the orchid you just repotted into sphagnum moss. To cover it like that is a good idea if it was in bark, because the bark is a less retentive media. In sphagnum you will gewt very little if any drying. I would worry that it may stay too wet.
Should I not cover it then? Just keep in the moss? Remembering that I only have the one new growth for a root system and that I am trying to create roots. Also with my area only running at 40% humidity, I thought the bag would help with that is left of the leaves take in moisture for the plant. Of course I know with the moss that I will have to be careful with overwatering and water less often than I do with the bark.
