I'm thinking one could use a crosshatch trellis framed around the sides for the bottom. Attach flotation to the frame. Then use the shade cloth then biomesh. That should give good support, but allow for continuos watering of the plants(wicking).JUST IN CASE it doesn't rain for a long time. I've got to have a plant island. Was considering just putting in a piece of plywood for shade, but Eric's invention is 1st class.
