I can't speak to the hydro-physics of tight moss (sorry Ray!) but loose moss stays wet and soggy, while tightly packed spag doesn't. The effects are that simple.
Additionally, high quality spag tightly packed in (I don't even wet it when potting my Catasetums) lasts for years, and I water every single day during the growing season. I unpotted several Catasetums that had outgrown their pots a few weeks ago and the moss was as fresh as when I packed it in about a year ago. Many will get repotted next next year and will still have good looking moss.
Bottom line, use high quality moss and pack it in. I'll let Ray (and other smart folks) figure out why it works.
