I don't know if you have heard about it, but I have seen a pic of a Vanda growing in a glass vase. The vase have a narrow neck allowing the top part of the plant to sit comfortably on top of the vase while its roots dangle and curl inside. The vase get filled with water, leave it for sometime (I don't know, maybe an hour) and then emptied leaving only just a little bit of water.
I thought about trying it, just for fun, see if it works, but considering the heat here during summer, the roots would probably end up boiled instead...lol. But I think it might work for you, because you live in a place with a cooler climate. The guy who grow this Vanda in a vase lives in UK.
Oh I forgot, if you are interested PM me and I will give you the URL.
