I am getting ready to make a water overflow with an old flower pot we no longer use. I was wandering if there are plants that can live in water only-no soil. I can if possible use fertilizer but no soil what so ever. If that is possible PLEASE let me know as this may change my design. So far I am going to have a 3 ft square. A pot in the middle and a pump on the bottom of the planter pushing water up to make it overflow into a rock and water only basin. I was just hopping for plants as well. OH! It will also be on my porch with NO direct sunlight at all.If no plants that is ok I will just have a waterfall. Any help would be great. I will post picks of the whole process once I begin.
