Default Watering Cattleyas

My first thought is that Uncle Vito should ask the Sta Barbara Estate what
they do ... since that regimen, whatever it may be, successfully grew the
plants for the however many years before he bought them.

But more generally, Catts tend to be pretty hardy and adaptable. In Belize,
where I've had a few opportunities to see them growing in the wild, the
plants get a lot of rain for several months of the year, but they also
survive a very pronounced dry season, during which they may get no water at
all (well, maybe a little morning dew) for a couple of months.

Here in South Florida, we don't water our mounted Catts any more than we do
those in pots with medium, and they do just fine. In a low humidity
environment, I think more frequent watering would be advisable.

But as a testimonial to the "hardy" part: We dropped a tray of bareroot
Enc. alata while unloading our trailer at the end of a show. Several weeks
later, while loading up for the next show, we noticed that some of them had
rolled under one of the shelves. All survived, and most were in spike,
after at least 6 weeks in an ungodly hot, dark environment with no water at
all. Not that I recommend such treatment LOL.

I think the "don't like to stay wet" part of our knowledge of
orchid-growing comes from suffocating the roots in insufficiently airy
media, and not from too much water, per se.

Taking a clip from The Baker's orchidculture.com free sheet on Cattleya
skinneri, for example:
_____________________Plants usually grow in wet mountain forests from near
sea level to about
4100 ft. (1250 m), but they also occur on rocks at higher elevations where
rainfall is greater and evaporation is less._____________________
That sounds to me like "staying wet" is the norm. We have to consider,
however, that the root systems are very much exposed (sort of like those
of "Uncle Vito's" plants) to air so they important gas exchange processes
that occur through the root systems go on unimpeded.
