Moving Angreacum and others to SH

[Rothrock42]

I have an Angreacum magdalenae, Angreacum sesquipedale, Aeranthes Hsinying Ramosa, and Trichopilia marginata which are not thriving like my other orchids -- cattleya, dendrobium, neofenitia, catisetum, phal, phrag, paph, y'know a lot of different genera.

So three angrecoids and an oncidiinae.

I've had these for about 8 months to a little over a year and none of them have grown anything and a few have lost a couple of leaves. Additionally I sunburned the magdalenae, so the situation is pretty close to dire.

I think what they have in common is they don't want as much of a wet dry cycle as my other orchids. Given my setup and situation, I'm thinking that I need to move them out of bark and into SH to provide a more consistent level of moisture.

I've read that I need to encourage root growth before I move them. I've given them soaks in Super Thrive, but haven't noticed anything.

Any suggestions on how to save them and how to move them to SH?
