On June 25th when I first saw this thread I decided to go out and divide one of my Peace Lily plants. I washed off all soil and took two glass vases of different sizes, put washed/cleaned pebbles into each vase, placed the plants and added more pebbles to anchor them. I then added water just to a level just below the top of the pebbles. It's been almost two months and they seem to be doing fine. I keep them indoors and only moved them out to the screened porch (brighter light) for the photo:
