Orchids other than phals for beginners

[LadySoren]

I know this has probably been asked, but I tried to search the forum, and I just can't find with the wording I'm using.

Anyway, if a beginner wishes to branch out from Phals, what orchids are easiest to care for?

My environment-
Indoor
Light:: No good windows, so I have to use a 23W CFL in a clamp/reflector type lamp, so far it's ok except for one of my phals. No idea the foot candles. :-/
Humidity:: Honestly I have no idea. I use pebbles and water for now. I don't own a hydrometer. I call my Western NC indoor AC/Heat climate "dry" because I grew up in Fort Lauderdale FL so that's all I know to compare it to. Maybe it's "humid" here, but I only notice when it's raining. lol
Potting:: clear plastic pots, bark, perlite, and charcoal (mostly bark)
Fert:: KLN and Dyna Grow for now every so often, not together.


((I'm the same person who's husband ordered a vanda online and I almost had an anxiety attack over it so he canceled the order and got us another mini pha. hahah oh man...))

Any suggestions? I have 4 phals and a Ludisia Discolor (which I'm still new to, but should be easy right?).

maybe I shouldn't bother....
