A good way to tell if the roots of any orchid is healthy is to soak them or water the roots from a faucet. You will be able to identify any dead roots and trim them away when you are repotting. if your vanda is in a basket and the roots are exposed to the air and hang free than that is how you want it to be, but i am in florida so you have the right idea for keeping the plant hydrated. vandas roots hang free in the wild and that is why it can be difficult to keep them hydrated. they also LOVE heat, sunshine and humidity and in my personal opinion misting is not enough to really keep them hydrated for good growth. It is very hard to create a humid climate inside. If I lived up North I always thought that one of those warm mist humidifiers could be a worthwhile experiment (and actually in the winter they are great for dry sinus). Also, a small fan blowing on your orchids is a great idea as well. Love the idea of hanging your orchids in your south window.

Hey, Mantis. I wanted to let you know that I agree with almost everything you've written so far,
except for a couple little details.
1. Heat...
Not ALL Vandas appreciate the heat. Some will actually suffer a bit if it's too hot. One example is Vanda roblingiana. Although, they can tolerate it. Most Vandas actually grow just fine in moderate temperatures. A few, such as Vanda coerulea or Vanda coerulescens can take it down as low as 36 F (that's almost freezing, you'll get a light frost if any of you experience this temperature).
I'm going to also throw in a bit of a curve ball...
2. Sunlight.
While a good majority of Vanda hybrids and species do need strong light exposure to survive, there are the black sheep of the family. One that I know of right away is Vanda lilacina. I burned this guy thinking that it needed strong light. Boy was I wrong. It actually grows just fine in light that suits the mottled leaf Paphiopedilums.
While I understand you're speaking in generalities, I'd like you to be aware of these things with Vandas.
I'm not perfect either, I'll slip up and say things only to find out what I said isn't exactly accurate or precise. I hope this does not offend you, it was not meant to be.
FYI this is why I try to type in words like
"most" or
"may".
Just thought you'd like to know more about your keepsakes.
