I understand now, thank you. I just bought a package of the Kyoto Moss. If the Buddha head is turned into a waterfall do you think the moss will still grow on it? I looked for java moss on eBay, we don't have it here in town, but it looks like most of them are selling Java Fern, which I already have for underneath the water. Are the two the same? I don't think they are, but maybe I'm wrong.
