Can Cymbidiums grow if kept permanently indoors?

[Gazpacho]

Hi,
I am new to all this. I have a 6m x 4m room with an operable louvred roof, and with windows that face North (equal to a South facing window for those in the Northern Hemisphere), so the lighting is good, and the ventilation is high. It could have direct sunlight if I need it, or I could exclude it by adjusting the louvres.

*I cant insert a picture as I am a new user*

For delicate plants, I've put them under the Northern window which is has the sunlight filtered by a patterned obscure laminate fixed to the glass so the plants do not get direct sunlight, but do get very bright light especially in the afternoons.

I have a number of cascading type Cymbidiums that I would like to hang so that their flowers drape (if I can manage to get them into flower).... But everything I have read says I should be keeping them outdoors.

I wonder, in my circumstances, is that necessary? I mean, am I wasting my time attempting this?


Thanks Gaz
