Hi chef marc,
this thread you have dug up is 9 years old. People are rarely active on these forums that long.

Welcome to OB. Vanda's are not considered the easiest of orchids, if you are worried about temperatures I would recommend you consider a Cattleya, they are generally more cold tolerant.
Do your research though, something like a cattleya maxima or hardyana can handle 40+F no problem but something like C luteola or C Dowiana or one of its hybrids generally does not like the cold.
There is far more info regarding Cattleya than there is Vanda's. I know some can tolerate the cold better than others but I've come to experiment and try what works, some show signs of stress from cold where others won't.
Vanda Coerulea or Vanda Denisoniana should be able to handle those temperatures if you do really want a vanda. The denisoniana can be tricky to find but there are lots of hydrids of denisoniana which should be good candidates. I have 2 Denisoniana hybrids a vanda Sukontharat and vanda Batram. The Batram can handle those temps, my Sukontharat could not even though they both have V denisoniana as a parent.
