Microfiber collar?

[MateoinLosAngeles]

I've heard about the "collar" technique from some Orchid Societies in which you basically make a Sphagnum collar around the base of the plant to foster root growth. I stumbled upon this Vietnamese youtube channel which shared a tutorial to foster root growth in rootless orchids:

He attaches the rootless orchid to a stake with zip ties, then ties a microfiber string around the base, places it in a cup of water with the plant standing above the water but not touching it, while the microfiber goes all the way to the reservoir and wicks the water up.

I've seen the microfiber trick as a self watering hack, especially for vacation periods. But has anyone tried something like a microfiber collar to foster root growth?
