Dry / dehydrated vanda roots

[Orchidguy88]

Hello,
I have recently purchased a vanda (V. DR ANEK x SIMIRANE LEK (M) .. that's what it says on the tag, from a local show. Of course excitement took over and didn't completely inspect before purchase, I'm hoping my new addition will get through.
I feel it's extremely dehydrated, the roots have cracked places previous to me and they are all green, but not really a good green.. I don't think. really only the roots I'm concerned about, I have gone through with tweezers and cut away anything dead. I have been soaking it in a bucket 2x a day for 30mins - 1hr for about 7 days.

Here are some pictures, I'm going to continue to soak it hopefully I see new roots.
I hang it in a south patio window, sun in the morning
I don't monitor humidity really.. sorry :-/

Any opinions helpful tips appreciated
I have been on the look out for a big enough vase (not sure yet)
The roots on this thing are externally long, they look really healthy at the bottom. Kinda white when need to be watered and a nice green when watered. But up close to the base of the plant looks brittle some are thin, I have I would say maybe 2 good thick roots at the base out of 4, but they have pretty evident cracks in them.. big roots branch to small, small turn healthy at the bottom.. I don't want to cut the good..

So many thoughts,
Thank you
