Looking for alternatives to moss

[Angurek]

I'm looking for an alternative moisture-retaining medium for hanging baskets. I'm pretty much done with moss; it gets nasty after a short amount of time, suffocates the roots, and is a pain in the butt to unpot from (it has a tendency to stick to everything, so getting rid of it all is tough. On top of that, fungus gnats love the stuff).

I haven't had experience with media other than moss or bark, so I'm not sure where I'd jump to from here.
