Hello Lawngnome to the BOARD!
Hey another Californian!!! YO
First orchid, dendroboard: sounds like quite a combination especially if you are trying to grow a phally in a viv!
As a first orchid, phalaenopsis appears to be the one that is commonly grown in the home. Seems like most home hobbyists start out with it. Guess that makes me the exception. I made a greenhouse and started out with paphiopedilums!
Have an OSH in your neighborhood?? A Home Depot? Your best bet for an inexpensive phally would be at one of these two places. I have read of phallys being sold at WalMart but the only orchids that I have seen at the local one are dendrobiums. I have a feeling that you may pick one of these as a second orchid.
A lot depends on your tastes and what you can find for the $$$ you can spend.
You may want to check around in your area to see if there is a local orchid society and get involved if you have the time. Also find local orchid growers and visit them. You can learn a lot up front and see live ones too!!! Be a good starting place.
Most of all have fun seeing the plants and making new friends!!
