Spawn Bags
Price range: $28.00 through $65.00
Sterilized Milo Sorghum Grain Spawn – 3 lbs bags with injection ports.
Spawn bags will be shipped in 3-5 business days. All spawn bags will be shipped USPS Ground.
Description
Sterilized Grain Spawn: 2, 3, 4 or 6 bags fill with three pounds of hydrated Milo Sorghum grain.
This sterilized grain is sealed and fully sterilized in a spawn bag with a 0.2-micron filter patch and a high-quality injection port.
This bag allows easier shaking and optimized colonization as more grain is touching other grain and not the plastic, all while allowing us to ship them to you faster, easier and cheaper: getting you the best price on the market!
In order to provide superior pricing we only sell this item in increments of 3 or 6 bags for now.
Sorghum, also known as milo seems to be the superior mushroom grain spawn. It consistently outperforms rye, oats or corn in our tests regardless of how we prepare them.
Sorghum It has relatively high protein but most importantly it has a lot of surface area due to it’s small particle size. The more surface area your the grain in your spawn bags have, the faster the mycelium will spread in the sterilized grain bag and the faster the colonized mushroom spawn will colonize the bulk substrate as it will more evenly and intimately mix through the bulk substrate providing lots of inoculating points. This speed reduces risk of contamination and makes it so your mushrooms can fruit as fast as possible.

I’ve never had any issues with these spawn bags, in fact, they seem to work better than others that are available! I’ve never had a single issue! I’ve used others and had mold. I’ve never changed how I’ve used them, so that tells me it was the spawn bags! Thank you Boomer! You Rock!

Ashley is a life saver. I had a small hole in my tub and I used the patch to fix it . Within one day she responded to my email and sent another replacement out! I also ordered her spawn bags and they have had such speedy and healthy mycelium growth so far! I will be a long term customer because of her quick response and solution to my issues. Thanks Boomer Shroomer
SHANNON (verified owner) –
Definitely a great value for getting 3 spawn bags. They work great and the one time I had a bag that had a faulty filter, Ashley sent me a new one immediately. I have been buying my supplies from Ashley and she has always delivered quality!
Marqus M (verified owner) –
I ordered 24 – all arrived with no contam but all were a little too wet. BUT every single one of them worked 100%. Very happy with products and customer service here! They even throw in freebies when you make big orders. Respond quickly to emails also and are very friendly!

So far all is going according to plan! I did have some mold contamination in 2 of the spawn bags. That was after I injected spores. So I think it was a temperature issue.
Andrew (verified owner) –
As always, super dependable and a quick ship!
Derek (verified owner) –
Great product! Being a new grower I don’t have any basis for comparison personally, but all 3 bags so far have colonized very well no matter which strain culture I’ve used so far. I have 4 more freshly inoculated bags (literally yesterday) and feel confident that they will also work out great. Thanks Ash!
Robert R. (verified owner) –
Excellent as always
Dan –
Happy with my purchases. Fast shipping (granted I live fairly close). This is my first experience attempting to grow. Just saw my first pins with my one of my first two spawn bags a couple days ago. The other one, was a different strain and the spores took a bit longer to germinate but has started to grow. I expect to harvest my first flush in the near future.

This makes it very simple to get started. I’m not sure if I stay with this level of cost in a large scale development but these are my ‘go to’ bags for test runs and one offs.
Fast shipping and ell packed

Christopher T. (verified owner) –
The injection ports were definitely self, sealing the filters on the top of the bags were good quality. I didn’t have any contamination in any of the grain so overall, I have nothing to complain about it. Did everything it was supposed to do
Brian G. (verified owner) –
This is the only place I buy my spawn bags and I very rarely have contamination.
Marcus (verified owner) –
I was excited to receive these grain bags. I told her about my experiences with other companies sending contaminated grains. grain bags are colonizing well.
