I think Bellini might be a brand of orchids sold in supermarkets. Is that what you meant? There are different kinds of orchids with different requirements, so we'd need to know what kind you have.

They prefer to be very warm all year, not lower than 65-70 F if possible. They like the highest humidity you can give them. They don't need any sun shining on the leaves. Bright shade is fine. They need lots of air at the roots but they also don't want to dry out.
If you use the Search function in the top maroon menu you can read how other people here have grown them.
