   Sphagnum moss works great!

   Don't use so much, just enough to cover the holes in the bottom
of the pot. The peat mix or the moss can both start to get funky
from sitting in water all day. Sometimes water should be flushed
through to pot (don't do this to seedlings!!!) and the water in the
tray has to be changed.
   This will help keep you soil "fresh."

   Yes, I think you are the right track, here. Charcoal has not
harmed my plants, and it also seems to help airate the soil, similar
to how perlite does this... It's good for Nepenthes soil's, at least
for most of the common mid-highland to low-land species. I don't
know how (if) beneficial it is for Sarracenia though.
