I have dwarf sag sprouting all around my tank, about 10 plants. I did a quick tear down of the tank for new flooring and the substrate was put in a giant tote (in wagon). Before I put it back in the tank, over a month and a half later, I thought I had picked out all the left over plant parts. Guess not. A couple of them are at least where I was going to plant it, so I guess add another win.
