I also have one of those little seedling catts that I bought last year. I keep it under fairly bright light and near my humidifier and it seems to be doing really well. You can find basic cattleya culture here. The hardest part for me is making sure I water it enough; being in such a small pot it dries out fairly quickly. Your best bet is to follow the orchid sheet in the link. If anyone else has more info I hope they chime in
