Trying my vandas in vases, need input.

I recently ordered 1 v. coerulea, and ended up with 4.

There are 3 that are fairly small, 1 that is medium, and as far as I know non have previously bloomed. Right now they are all in glass jars/vases bare root with some florist wire for them to balance on to keep upright. The largest is in a basket in the top of it's vase. They all have fairly small root systems, and so there is nothing to help hold the humidity in. I soak them once a week with weak fertilizer, and spray the roots in the morning. They are in a southern facing window.

I want the roots to be dry by the evening, right? Right now I have some airy cloth wrapped around the top of the vases to help hold the humidity in, but I'm not sure if this is the best idea, or if it's even necessary. It is fairly dry here, and in June I'm moving to Arizona, where it is even drier.

I'm wondering what I can do to encourage lots of root growth this spring/summer. Currently they all look a little sad, I received them with damaged and misshapen leaves, so none of them really have that lovely Vanda shape yet.
