water lily in the bathtub?
I'm thinking of making an old cast iron bathtub (which is still installed in one bathroom in my house, but never used) into a water garden. But I don't want to put plants in soil in the water, because of the danger (or inevitability?) of clogging our pipes.
Is there a way of planting water plants in something that will not go down the drain and clog it? I have a particular dream of having a water lily floating in this tub. Is there any way to do this without soil or other substance that will clog the plumbing?
(note: I can provide appropriate light artificially (maybe)(or maybe not strong enough with artificial lights?)
