My concern about this would be the decomp rate. Will dead Sp. Moss not rot pretty quick? I think it would do fine for moisture, but again, I think the medium would break down too quickly.
Good to hear others views on this.

No not spaghum. The bags just say Spanish Moss. It is long fibered and a light color. Kind of silver and white sort of. Not as course as straw. Sometimes you could see it as a top dressing on certain plants probably for humidty. They sell it everywhere around here Nursery's Home Depot Dollar Tree etc.
