OUR MANURE SUBSTRATES WILL OUTPERFORM ANYTHING YOU’VE EVER TRIED!
Our pasteurized, composted, manure based mushroom growing substrate is made by our local, professional mushroom compost producing friends. Our friends have been producing commercial mushroom composts since 1958 and know a thing or two about dung loving mushroom substrates. Compost used for mushroom growing is specifically formulated for commercial levels of production, this is not the same as spent mushroom compost for gardens, that’s the stuff that’s already been run through!
This is an actual photo of the facility where your new substrate is made!
Your purchase will arrive in sealed, 4-5lb bags* – and is perfect for dung loving mushrooms (coprophiles) like Agaricus blazei, Agaricus bisporus or other cultivated species of dung loving mushrooms. 💩🍄
*The volume does not change for the bags, depending on the composition of the blend the weights range from 4-5lb. This new blend is much more voluminous than our previous manure blend.
🍄 This manure substrate is perfectly suited for ANY dung loving mushrooms! 💩
Grow directly in the bag, you can remove the top and case them (leaving 1-2″ of plastic for a perfect micro climate) or dump into a tub (4 bags gives a nice fill for a 56 quart tub) or many smaller containers (trays etc..) for spawning. Whichever route you take, this manure based mushroom substrate will without a doubt satisfy your home mushroom growing needs!
“I like how it performs, but why is this substrate a bit slower?“
The simplest answer to this is that there is much more available nutrition, and your mycelium is working hard to break down, digest and finally form fruiting bodies. On average you can expect an extra 5-7 days for colonization, but the wait is worth the 2-4X production, dense fruit bodies and happy harvests 😉
“What is the exact blend? Is this horse manure? 🐴💩”
Our previous blend was composted cow manure, it worked great but having experience in the commercial Agaricus industry, and seeing commercial levels of production using a highly specific blend of ingredients to optimize production and make the term ‘pounds per square foot’ something that home growers can start talking about. That said, here are the ingredients used, in no particular order, to blend together the best mushroom growing substrate possible:
Cotton Seed Hulls
Your substrate has been meticulously prepared, analyzed and each batch is lab tested for quality.
“What is the white stuff I see (mostly) on the corn cob, why is the corn cob even used?? 🌽”
Actinobacter remnants on corn cob in our substrate
Referred to as actinobacter, this white growth is used to break down the raw ingredients into easily digested inputs for mushroom growing. I like to call it actino because saying actinobacter is weird 😂 This growth has been killed off but remnants may be in-tact and appear to be contamination but rest assured, there is no risk to your experiments!

The corn cob itself is used to buffer the high nitrogen content of the manure and add some carbohydrates to the overall nutrition of the collective substrate. No agricultural waste goes unused in mushroom growing!
With new things it’s nothing to be ashamed of if you need anything clarified or are concerned with trying something different. If you have any questions, don’t be shy to email us at LetsGrow@MycTyson.com and remember, while this is well suited for growing all dung loving mushrooms, we cannot offer advice which is Federally illegal. Please do not ask about using our product for anything illegal or you will be ignored. Don’t make us do that! 😂
Shipping is in flat rate boxes only. If you order alongside other items these will ship separately.
This keeps costs lower (free boxes & supplies) as the weight (up to 30lbs can go in a large flat rate) is heavy & can be expensive to ship regardless of location, doubly so when you order more.
Your mycelium says ‘Thank You!’ in advance 😂😁🍄
