Whether you’re a beginner or advanced researcher, these bags are ready to deliver exceptional results—sterilized, sealed, and prepared for effortless inoculation.

Why Our 5-Grain Mix Works Better

✔️ Maximum surface area – more inoculation points = faster colonization
✔️ Strong nitrogen profile – supports up to 4 flushes
✔️ Non-clumping – grains are soaked, simmered, and dried to perfection
✔️ Fortified hydration – blended RO + mineral water, gypsum, Calcium+, and DAP for balanced pH and nutrient-rich environment

Let customers speak for us
giving a five because Midwestgrowkits.com is so good to me, but these were misdelivered in the mail. Luckily the neighbors brought the items back, but had a few cold nights. Im hoping there all good, starting new projects before winter is here. All year Midwestgrowkits.com made my needs were met. Can't wait till next year and spring heat returns. Thanks to everyone there, recommend 👍 💯
These are really cool! Long term storage of your favorite genetics without having to keep doing dish transfers. Midwest Grow Kits just has the best quality of everything!
Perfect agar! Great job on agar quality, plate seal, and overall packaging. Many other vendors don’t seal and package well and the agar can start to lose volume and arrive in bad shape. These are my new favorite.
Great customer service, all products are sterilized ,I've been having great results with no contamination
Love the products.. so far everything has panned out perfectly. Keep up the great work
I love how well packaged your products are.
I'm always guaranteed a vibe in my fruits.🍄🍄
Quality product. I hope to order more as my business grows.
This is exactly what I was looking for. Good structure… a winner! And thank you for the extra freebies my last order.
Grain bags are great I wasn't happy with the agar plates because they weren't wrapped individually and you didn't send any para film I feel like you guys should replace the five agar plates that I got when I undid the main rapper the lids got Jarred around and they ended up contaminated all of them but one the one I called a mushroom with so out of the five I only was able to use one of them but other than that your business has been great I love every product of everybody I bought a grow kit from you guys a few years back but overall very happy with Midwest grow kits
I got the 45 dollar all in one bag with monotub and their tubs are the best, their all in one bags are the best and cheapest, amd their substrate is the best with more mushroom growing ingredients than the competition..
I am going to buy the jars next so I can reuse for liquid culture,bag of substrate and 2 monotubs bc their tubs work wonders compare to modified bins. Simply the best in the business.
So far this culture has been great! I used my own spawn bag and so far, the mushrooms have been growing like a charm! Right now the mushrooms are still cultivating, but so far there seems to be no contamination, and everything is growing as it should!

On 8/29 I inoculated all 3 jars . 2 with albino penis envy and the other with Psilocybe natalensis. As of 9/5 The later has EXPLODED to about 25% inoculation of clean white mycelium and the other 2 are considerably less due to that strains nature of being a slow grower, but still had about 10% clean mycelium growth. So far AWESOME results
I needed to replace a grow light that I thought I had lost, after it arrived I found the other so now I have two.
Very fast shipping, and great quality like you come to expect with MidWest

Excellent service,will use again!
A set of bags w/ 5ml of spore juice in each will do the trick. Give the bad a good massage and another one at about 1 week. 10ml per bag will grow even faster but it is not necessary. Mycelium loves this grain combo.
Both bags showed up on time an perfect ontop of that my bags are all white with mycelium! Almost ready to buy that black cow mix an get to growing!thanks guys
