If the orchids are growing and booming, they're getting what they want.. don't need a "fake dry season". It so much depends on the orchid. Many don't even want a dry season. And with a few exceptions, even those that might expect one don't really need one if they get a chance to dry out between waterings. Hint: Of those that do expect a drier period, mounting seems to make it not matter...
I live near one of the largest species nurseries in the US (Andy's Orchids)... plants are organized by temperature needs (vertical placement gives different light levels) Within those greenhouses and shadehouses, there's a huge variation of species, some of which have a reputation of needing a dry winter. Everything gets watered (probably a bit less in winter, because it's colder)... those deciduous Dendrobiums and others like that do just fine, since they're mostly mounted and dry quickly. So... the "dry period" for most seems to be not all that vital. (There are exceptions like the Catasetinae that really do need a dry period... but then there are exceptions to any generalization that one might make)
It's impossible to give everything in a varied collection exactly what it needs... but fortunately, a very large number of orchids are very adaptable, and it's possible to "reach a compromise" that works.
