Cattleya growing needs? (n00b alert!)

[trinityoaks]

I have three Cattleyas:

C. Carl Hauserman
Lucky Man
Volcano Queen

(I have a Phalaenopsis, too, but I've misplaced the tag with the name.)

The first two I've had for three years, and they seem to be healthy (in spite of my ignorance and neglect) but they haven't bloomed since shortly after I got them. I just purchased the Volcano Queen, and it has no blooms yet.

I'm gathering from what I've been reading that each species has its own specific growing needs. Can someone provide me with requirements for light, temperature, humidity, and water for each of these species? A Google search hasn't gotten me very far.

I just repotted them in a bark mix for orchids, in unglazed terracotta orchid pots. Afterward, I gave them all a good, 20-30 minute soaking in filtered tap water, then drained them. They're each in a slightly larger outer pot, plastic with a raised base, with water just to the raised base (below the bottom of the clay pot, for humidity). I hope this is the right thing to do for them.
