Premium Organic Spawn Bags

Spawn Bags are the next generation in mushroom growing. They are the perfect add-on to any of our mushroom kits! Each bag can produce the same as 8-10 jars! Once thought to be a more advanced method for growing mushrooms, we have designed our bags to be much more grower friendly than any others we've seen and tested! All of our spawn bags include a self-healing spore injector port.

The Original Rye Spawn Bag

Midwestgrowkit's Organic Rye berry spawn bags are the most popular add-on to any of our kits, simply inject 3-5 cc's of your favorite grain or dung loving spores into the self-healing injector port and incubate right next to your jars!

They have been one of our top sellers for the last few years! If you want to grow mass quantities, our amazing Rye spawn bags are an easy solution! Our 3 pound classic spawn bags are some of the biggest you can find!

Each bag contains 3 pounds of nutrient-enhanced organic rye berries and a mixture of distilled and mineral water fortified with gypsum, diammonium phosphate (a fertilizer/nutrient to provide an adequate amount of nitrogen, and correct PH) and other nutrient enhancing herbs and minerals. Each spawn bag has a built in filter patch for gas exchange and a self-healing injector port for effortless and error proof inoculation.

These bags are guaranteed to arrive to you 100% sterile and ready to inoculate! Each spawn bag is professionally sealed and pressure sterilized at 15 PSI for 120 minutes.

Our Spawn bags come with their own step by step photo guide.

We also include a separate step by step guide for advanced growers on bulk spawn growing.
