First of all. Welcome to the Orchid Forums!
We have several ongoing threads and posts about Phalaenopsis care. Your orchid is a Phalaenopsis.
We also have a great 'sticky' entitled "Growing Supermarket Orchids-Phalaenopsis". That is packed with a lot of good information on how to grow them. If you scroll back through the many pages in the orchid forums, there are several Phalaenopsis specific threads.
We all are at your service!
