    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!

    Worked, but wet

    Pros:
    • Value
    • Easy to use
    Cons:
    The first time I ordered these bags they were exceptional! Packaged nicely, arrived quickly, and everything looked exactly as it should. The second order I placed though, both bags were obviously more wet and had burst and mushed grains (one being a little worse than the other). I decided to inoculate them and take the chance. They both colonized well but unlike the first batch of bags I ordered these took a bit of work and there were a few places that were just too wet to colonize, in those spots the grain almost looked like... oatmeal is the best way to describe it. They also took about 2 weeks longer to colonize than the bags I previously ordered and both sets were colonized in the same conditions as far as temp, humidity, light, etc. Given that I've ordered various supplies from Midwest several times with no issues I'm going to order these bags again and cross my fingers that the moisture issue was just a bad batch. I'll write another review or update this one if possible once the 3rd set arrives and colonizes.

    1 out of 2 ain't bad

    Ordered on 9/13/22, received everything quickly. On 9/24 inoculated both bags. Noticed one bag had seemed slimy and had what looked like a piece of shredded paper in it. Inoculated anyway. After a couple of weeks one bag was about 30% colonized

    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 :)
