Carolyn, I have been planing a small pond in the GH for a long time, too. Not the GH we just put up that is more of a working GH. But I have wanted to build more of a Conservatory attached to the house, for a very long time and still hope one day to do that. More of a Tropical Garden with a small sitting area and some kind of water feature. Small stream a few rocks and a pond big enough for a few Tropical WL and some fish.
