Hi Min
Welcome to Orchidboard
If you open the forums page, you'll see listings for all the different forums we have. Choose the forum your question would fit into and as you've done here, click on New Thread...and start typing
To answer your question: Phaius tankervilleae is a terrestrial so it does better in a terrestrial mix which is more like a soil compound rather than large chunks of mix. As for growing conditions, they like to be moist but not soggy and although they do well in various lighting, mine seems to do best in shade.
Do you have any other orchids? We'd love to hear more about them
If you have any questions, feel free to ask.
