Wrinkled Leaves?

[chucknora]

I'm trying desperately to keep my orchids alive. I'm afraid they aren't getting enough light, but just in case I'm wrong I'm asking here...

They seem to dry out every other day, which is fine, because they are right above the sink on a windowsill that gets no direct sunlight. I just water them in the sink and put them back. But the leaves are wrinkled and starting to get a little soft. They are also not as dark a green, making me think sun light issue.

I can get a florescent light to put there, but I don't know if that would be too much.

Any questions? Help?
