I'm assuming you mean sphagnum. The only reason to "soak" it in water is overnight the day you bring it home because it livens it up quickly (sort of like a jump start). The next morning/afternoon you can put it in a pot on top of dead LFS, peat/perlite, peat, peat/sand, etc. It'll settle into just about anything a CP will.
Place under fluorescents and keep it wet - top-water often, it likes oxygenation.
It can be propagated via cuttings if you're interested; look it up though, I think there's a specific way you have to do it.
