Just reserved a flask of Cattleya purpurata var. carnea, what do I do now?..

[peeweelovesbooks]

what do I need to buy now?

Pot size?
Medium?
fungicide(s)?
fertilizer?

I don't know whether I will be getting one, but I want to be prepared in case I do. So, any specific pot size? medium, fungicide? etc.. that I may need?

What would be the special light conditions? Also, I've seen in a gardening catalog a system that has a plastic cover that supposedly keeps the humidity high, and there is a water reservoir underneath? should I purchase this?

I'm kind of nervous (haven't even gotten the plants yet ) but I want to be prepared! thanks for your suggestions/advice.
