Thanks all.
We have a garden window in our dining room that's about 5'w x 4'h x 14"d. They would either go there, or in the den in front of the patio door. The garden window gets plenty of indirect light,while the den varies depending on what plants are placed there. In either case things get watered pretty regularly. Generally, the amaryllis, jade plant, spiders, cactus, and other small stuff goes to the window. The ficus, poinsettia, and larger stuff goes to the den. (I would LOVE to have a real greenhouse, but I keep getting voted down.)
What appeals to me about the hanging option is that they can be put 'high' in the space and the shelves left available for other pots.
