Turn your leftover trash into a gourmet delight with this 5 lb Cardboard and Coffee Bulk Starter. Use wood, paper, dried vegetable matter, and even coffee grounds and filters to grow your own crop of healthy, gourmet Warm Blue Oyster Mushrooms. This 5-pound bulk kit will inoculate up to 25 gallons of cardboard, coffee, shredded paper, and more. For most homes, this will consume the entire output of your paper waste and turn it into a delicious crop of gourmet mushrooms that are rarely available at the grocery store because they are best eaten fresh. You can't get them much fresher than straight from your own backyard.

Note: If you can't plant the plugs right away, the spawn may be refrigerated for 3 to 6 months, but never frozen. Do not let spawn sit in the sunlight.
