Mark,
These orchids are almost impossible indoors.
They are real 'cloud forest' plants.
There are lots of other orchids beyond the usual cymbidiums and moth orchids
That can be grown with a bit of care indoors.
Take a look at the cattleyas and their relatives for a start.
The large flowered vandas that you sometimes see in glass vases are quite easy
If you are happy to spritz them with water each day.
Both these types of plants like sunny conditions.
There are plenty of other species and hybrids if you want to delve into it,
Regards,
David
