I have a cat box that I filled with water and emptied a bag of the dried LFS in it. Then I placed my U. macrorhyza in it. From what I read, the aquatics need solid material to latch onto. So now I have an outdoor mini-swamp. I'm also hoping the dried LFS will come alive before the snow flies. And for grins and chuckles, I placed several leaf cuttings of D. binata & D. filiformis on top. Whaddya think?
