Growing in a Greenhouse Window?

[quiltergal]

I was reading a book last night that extolled the virtues of growing orchids in a greenhouse window. It recommended that the window have a south/east, or south/west orientation. It recommended a shade cloth on the inside of the window during the summer months to keep the plants from frying. I'm curious if anyone here is growing in a greenhouse window, and if so if it's working for you. Thanks!
