Casting Grow Anything!
  • To produce our castings we use cow manure that has
    been composted for a minimum of 15 days at 131 F or
    higher. The composted cow manure is fed to the worms
    and after 3 to 4 weeks the castings are harvested by
    screening through a 1/8 screen.
  • Small fibers from the manure and occasionally some
    worm eggs or small worms will fall through the screen
    along with the castings.
  • No peat or any other non sustainable products are used
    in our castings / vermicompost product. Black Star
