I wonder if there is a coating on the window that won't let certain light
wavelengths in?

I live in the Los Angeles area, and have a large number of orchids.
Among those are dendrobiums. With the exception of one, I get good
leaf and root growth, but have not had any blooms.

This is in an apartment, with south facing window (soon to be
west-facing).

Any ideas are greatly appreciated.
