I just finally watched the video. As he said, the roots will go through the mesh, and that's all fine and dandy maybe for the tropicals, which as he said are smaller round bulb tubers, but I still think it's a mess waiting to happen with hardy lilies. Those are much stronger, and they will go through the mesh, and continue growing until they find something else to grab onto. In the solid pots, this never happened. If you use the mesh pots, try to find smaller lilies that don't get as large, that would help, too. I'll be anxious to hear your conclusion by comparing the mesh to solid pots, Shinksma. I hope both work well for you. The pots in the video were small, so maybe they will grow just fine in them. I just see cutting off a ton of roots to separate the tubers. Come to think of it, when I separate the tubers, most of the roots come off anyhow, so maybe that is no problem.
