About a week ago I bought and hung a Phalaenopsis in the window in my bathroom. I saw hanging orchids at a botanical gardens once, and, figuring they're epiphytic, I thought it would thrive, especially next to the shower. There's no pot--just hanging on a couple pieces of string.

It's very quickly become droopy and thirsty looking. I'm surprised and hesitant to just think it's lack of water, because it's only been a week and I never knew an orchid to be so sensitive to water. Then again, it's hanging so dries out quickly.

My other thought is that it's the temperature. It's hanging by the window and the bathroom, while not cold, is one of the cooler rooms in the house, and the temperature has dipped outside the past few days. Can cooler temps cause a Phal to droop?

I'm spraying it with water once or twice a day to see if that helps, but there's no sign of recovery yet. Light-wise it's behind partially closed blinds right next to the window so it get's quite bright, but indirect, sun through most of the day.

Any advice would be much appreciated!
