Nathan,
Go to The Natural Gardener on Old Bee Caves Rd. -- they have great soil. I use a 50/50 mix of coco fiber and either the bag-it-yourself Hill Country Garden Soil (cheaper) or the already bagged (1 cu ft). Both are the same (Lady Bug Brand) and do not contain cedar. However, their
potting soil does contain cedar. I've never had to fertilize as of yet - 10 months and plants are thriving. Even though it's organic I still heat it up to 350F for 30 minutes. Also, their indoor tropical room is AMAZING. 90% of my vivarium plants come from there.
They also have organic long-fiber sphagnum moss which I use in nest boxes -- 2 cu. ft. bag for only 20 bucks.
I've experimented by adding a little sand (also from the NG) to the mix but the plants just don't do as well.
Also, for Live Tropical moss, T and C Terrariums in Fla.

uses organic soil for the base. I ordered 2 sq. ft. ($25 total incl. s/h) and this stuff arrived just thriving and months later still is. I've even got ferns growing out of it now!
There's another gardening place right there on Quadalupe that has the Lady Bug Brand if you don't want to drive all the way down to Southwest Pkwy.
Sarah.
