Here is a long thread on keeping moss as a houseplant that I pulled off my twitter, wrapped up as a blog post - so now you can read about practical moss gardening without having to visit that website :>
@abundance This is awesome! I tried moss gardening a few years ago and failed because of the lack of knowledge and a severe sickness I had. But for a little time I could enjoy it though. Thanks for sharing. Maybe I start again someday.
