    Our 5grain spawn has topped itself once again! With new grains and production process, these top selling spawn bags are one of a kind and not available anywhere else. The size, quantity and potency of the mushrooms these bags produce are simply amazing!

    The combination of several small grains helps provide more surface area and inoculation points which speeds up colonization times by 30%! Each bag contains our unique blend of minerals and a mixture of distilled and mineral water fortified with gypsum, diammonium phosphate (a nutrient that helps nitrogen release, and correct PH). Each bag has a built in filter patch for gas exchange and a self-healing injector port for effortless and error proof inoculation.

    • 5-Grain Spawn Bags (2)
    • 2 Quarts of spawn (Approx 2.25-2.5lb each)
    • Self-healing high temperature injection port
    • 3mm Polypropylene bag with 0.22 micron filter patch

    Our Spawn bags have their own own step by step photo grow guide and videos.

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

    (New & Improved Recipe!)  Over 10 years ago we introduced the new organic 5-Grain Spawn Bags. We are constantly growing and testing these bags and making sure what you buy today is the best they have ever been. In March of 2022 we improved our bags again by using only the best organic food grade grain available and updating many parts of the production process including:

    • Super clean organic cereal grains eliminate residues and starches.
    • New grain hydrating process and drying stations to perfectly hydrate and dry the outside of the grain prior to sterilizing
    • New mineral blend to promote germination and growth while preventing grains from sticking together
    • New 600 Bag Autoclave capable of higher psi/temperatures & reduces chance of human error during sterilization.

    The results are bags are one of a kind and not available anywhere else. We are seeing amazing results from recent grows. The size, quantity and potency of the mushrooms these bags produce are simply amazing!

    While the exact ratio is our secret, we start with organic rye berries as our base and add 4 other specially chosen grains to the mix including Red Sorghum, White Sorghum, Millet, and Red Winter Wheat Berry. The combination of several small grains helps provide more surface area and inoculation points which speeds up colonization times by 30% while still maintaining nitrogen & nutrients for the 2nd-4th flushes!

    Each bag contains over 2 quarts our unique blend of minerals and a mixture of Reverse Osmosis water and mineral water fortified with Calcium + Blend, gypsum, diammonium phosphate (a fertilizer/nutrient to provide an adequate amount of nitrogen, and correct PH). Each bag has a built in filter patch for gas exchange and a high positioned self-healing injector port for effortless and full coverage, error proof inoculation.

    These bags are guaranteed to arrive to you 100% sterile and ready to inoculate! Simply add 3-5 cc's of your favorite grain or dung loving spores! Each spawn bag is professionally sealed and pressure sterilized at 22 PSI for 180 minutes. Our Spawn bags come with their own step by step photo guide. We also include a separate step by step guide for on bulk spawn growing, which we highly recommend!

    We recently added 3 new autoclaves to our production center which are capable of sterilizing at higher pressures/temperatures. After some experimenting at different pressures we found that a 22 psi cycle results in near perfect grain. With our new autoclaves we can sterilize 500-600 bags at once eliminating almost all the human error.


    These bags are guaranteed to arrive to you 100% sterile and ready to inoculate! Simply add 3-5 cc's of your favorite grain or dung loving spores! Our Spawn bags come with their own step by step photo guide. We also include a separate step by step guide for on bulk spawn growing, and links to video, which we highly recommend!

    Pros:
    • Easy navigation web site / solid prices
    Cons:
    Quality Product - I purchased direct, fast processing / shipping, had my complete order in hand 5 days.
    I inoculated w/ Liquid spores on Wednesday @ 330pm, the room temp was constant 80, humidity was 55%-65%.
    By day 5 (the following Monday) I had some Major colonization on the bottom of the bag, i suspect the colonization started 1-2 days earlier, i did not wan to disturb he bag so i never checked the bottom till day 5.
    Ill be back :)

    After trying the jars, I’m trying the spawn bags which I find easy to use. I only use Midwest Grow Kirs for all my mushroom needs.

    Great results from all my research

    Pros:
    • The price was great for the amount
    Cons:
    • The tape that’s on each bag
    Come in discreet packaging and was well bagged and double bagged. Only thing was tape to get the bags apart. I might have actually created a small hole in one of my bags as I was tearing the tape off. I would suggest double siding each side of the tape before taping so the customer can get the tape off much easier, but overall, I’ve had great success with the 5 grain jars!
