I have a Vanda, wich is a hybrid I bought at a plants shop, intended for
room placement. The roots are on the air, sice the plant is only
suspended on a basket. My question is, how often should I spray the
roots, bearing in mind that my room meets sufficient light conditions
(a little morning sun), the temperature runs from 53 to 68 F, and the
normal humidity from 50% to 65%?


As often as you can, probably. You can't really over water a plant
which doesn't have any potting medium. When you do water, make sure the
roots turn an even shade of green - that indicates that they are holding
as much water as they can. And don't forget to fertilize. Vandas are
pretty heavy feeders.

In the summer you may need to water twice a day depending on how hot it
is and how much light you are getting. In the winter, maybe every
other day is good. 53 is probably on the low side for a Vanda, try to
find the warmest spot in the room. I wouldn't want to get much below 60
for most Vandas.
