Dendrobium Spectabile-Species, Need help with culture.

[Doug'sWindowGarden]

I just picked up a Den. Spectable species plant at the Central Florida Orchid Show this weekend. It was an impulse buy. There were a few on display in bloom and I thought they were awsome. They were pretty big and smelled great. The plant I bought is in a 4 inch pot, it has 4 canes with 2 to 3 leaves on each cane and a couple more with no leaves. The tallest cane is only 7 inches to the bottom to the leaves. I was hoping someone here might have some experience with this orchid. I didn't ask all of the questions I needed to in regards to the culture of this plant. Any information would be helpful. Blooming size, Amount of light and so forth.

Thanks, Doug
