This is a pretty modest setup but I thought I would share it. I have one large south-facing window, in my kitchen. Over the summer I kept my growing collection of orchids all over the house, but in the winter, this is really the only good place for them. So I added some shelving, and now I can fit 8 more orchids in this window area--ones that like a bit less light and a bit higher temperatures. So far so good!
