Although I began growing some of my orchids under lights last year, about half of my orchids hang in windows for the winter. Especially the larger plants and smaller mounts. The windows are a bit drafty and, although I have a humidifier boiling away two gallons of water per day, the humidity is far below what one would recommend for orchid growing. And the plants can feel downright cold to the touch. But here's what I have in windows this winter:

All of these are either mounted or in baskets or in suspended pots. And nowhere near windowsills. The wife's cats are devastating to plants that get within reach. Some of these plants are new and the Lycaste, in particular, might not be suited to life in my windows. Many haven't bloomed yet, because almost all my orchids arrive as small seedlings. Others have spent previous winters in the windows, but happen to be under lights this year. Since a couple unused windows will provide the next and perhaps the last available growing space, I'm curious what orchids other people have grown in windows. Successfully and unsuccessfully.
