Sounds like rice hulls would be great, however I know of no rice grown within a few thousand miles of us up here. I run a restaurant that uses several bags of mesquite charcoal per day, which produce abound 5 gallons of fine "duff" that can't be used for cooking. Should be plenty for my plants and farm...
That sounds PERFECT. Being where I am, you'd think rice hulls would be easier to source locally. Gotta hit the Central Valley.
