Help, four mature Vandas arrive from Motts

[early]

I ordered four vanda's from Motts last yr about the time the weather turned cold. They said they would ship when my area was warmer. And without notice, they arrived the night before I went out of my home to leave for the day yesterday. One was blooming but blooms wilted. I had rushed them in the house, openned and quickly stuck the roots in some water, They have long long roots, look a bit dehydrated , but no rot noted. The fans look very healthy. I had almost forgot that I had ordered them last fall.
Now I live in Arid NM, grow all my other orchids in LECA. It has been a while since I have read about mature vanda care. I have two yr old seedlings, tiny tiny with few buds of root. One that came with an oncidium from a nursery in NC, that is not growing and I just yesterday stuck that one with 5 roots about an inch long in LECA. I remember Ray saying a long time ago, Vandas can grow in LECA. I hope I remembered that right, So my larger seedling is an experiment. I have no memory of what you all have told me and what I have read about Mature Vandas except they like their roots in the air and forgot how ES told me to grow vandas in our arid climates. He is probably drier in southern AZ than I am at 5000 foot Rio River Valley in middle NM south of Albuquerque. And suggestion will be appreciated re growing the lovely health now Vandas appreciated. Meanwhile, I will go back to the sticky and vanda forum to reread what I have read many times but not retained much yet.
