Orchids for window growing?

[David]

Thanks Andy,

So both species roots needs to be very airy and plants needs to be placed in a more shaded area?

The maxillaria flowers really have a pungent odour. Let my son smell it. he said I don't like the smell... haa, haaa... actually after smelling it a couple of times it does smell a little like amonia. But I just love the leaves. It's different from the usual orchid's leaves.
