I have a modest collection of orchids that is outgrowing my southeast facing
windowsills. I want to move some to a northeast facing exposure. Since they
will get less light here, I want to select the ones that would do better in
lower light conditions (no or very little direct sun). Can anyone provide
some guidance? I have mostly phals, cattleyas, oncidium, dendrobium,
paphiopedilum.



I'd say you could safely move the phals and paphs. The paphs for sure.
You will probably find that this is sufficient for the summer, but if
your plants start to look a little starved for light in the winter, you
might want to supplement with a little electric light enhancement.
