hey, there's a pet store in Monterey Park called 'Central Pet' 1950 atlantic blvd.
They sell a 100 gram wad (with the water squeezed out) for $20, or small portions for $2.99
There is a large aquarium outside on the patio with all of the large clumps of moss, half of it looks brown and dead but I suppose if tied down, the healthy moss would take over.
They also have the largest selection of plants I've seen from any LFS. Anubias, crypts, stem plants, etc...
