Rootless Phalaenopsis orchid

[SamLo0001]

Hi all,

I got this Phal orchid hybrid from a nearby supermarket few months ago. Then I noticed the root has rooted. Follow that I experimented it with water culture (without knowing what I was doing), put it back to bark but heating the roots tried to get it to grow (all roots got rotten because of this).

I have put it back to water culture for two days with fertiliser and sugar dissolved in the water. This morning I had to change the water as it got murky and smelly; however, I noticed transparent coating around the root steel (the wooden part inside the root after the rotten bits got removed.). Due to moisture loss, I also covered the leafs with wet paper towels to prevent further water loss. To make the matter worse, the plant has a spike with two seed pods on it, meanwhile, a potential new spike/root is developing on the existing spike too.

At this point, I am still unsure what I am doing but is the transparent coating development a sign of recovery?
