Start of a journey (miniature Pleurothallid quaratine/prop box)

[BWG139]

I should be careful reading random sites on the internet, because that is not how I mounted either time. Both times I've had plants mounted upwards. Some of those have attached at least. I also don't have a covering of spaghnum over the roots, which hasn't caused any issues the first time.

Since my goal is an eventuality terrarium, would I be wise to remount now? I'm unsure whether to use cuttings or entire plants in that future project, as both ideas make me nervous.
