Willy’s Blend – Official Manure-Based Substrate
Exclusively from Midwest Grow Kits in Partnership with Willy Myco & Brown Treasure
Grow with the exact substrate used by legendary YouTube mycologist Willy Myco. After years of demand from growers worldwide, Midwest Grow Kits is proud to become the only official producer and vendor of Willy’s Blend in the continental USA—made with ingredients imported directly from Brown Treasure in Puerto Rico, Willy’s trusted partner and the origin of his famous manure mix.
This isn’t just another substrate.
This is the substrate the community knows, respects, and talks about—the same formula that’s appeared across Willy’s tutorials, grows, and side-by-side results for years. Time-tested. Grower-approved. Proven in countless successful harvests.
To support Willy’s mission of getting his famous mix into the hands of more growers—without delays or high shipping costs—we formed this exclusive partnership with Willy Myco and his team. Shipping from Puerto Rico can be slow and expensive, so by producing and distributing Willy’s Blend from our centrally located Illinois facility, we’re able to offer faster delivery, lower shipping costs, and a far more reliable supply. With our lightning-fast fulfillment team, growers across the continental U.S. can finally experience Willy’s Blend the way it was meant to be: fresh, authentic, and delivered quickly.
Why Willy's Blend Is Legendary
Hand-crafted, perfected, and refined by Willy Myco over years of personal experimentation, this substrate blend became iconic for one simple reason: it performs.
The core of Willy’s Blend is a premium mix of aged, exotic manure—naturally leached and dried for a minimum of 2 years. This aging process creates a nutrient-rich foundation packed with the micro and macro nutrients mushroom mycelium thrives on. A substrate that supports fast, aggressive colonization and produces thick, healthy flushes.

- Official ingredients imported from Brown Treasure
- Authentic Willy Myco recipe—no substitutions, no knockoffs
- Mixed, prepared, and sterilized in the USA by Midwest Grow Kits

Let customers speak for us
The preface, I typically do not use any manure-based substrates. I always get mold or something goes wrong. I live close by and I was in your store 2-3 weeks ago picking up my usual order of grain bags and substrate mix. One of the girls told me about this new blend and to give it a shot and write a review to let you guys know what I thought.
I want to say, firstly I only use the regular Select Bulk Sub, that always has worked great for me, I figured why not try this.
I have not heard of Willy Myco before but after looking at his Youtube and Patreon channels, he seems to be popular and a trusted influencer in the community.
I set up 4 tubs in my own homemade Sterilite tubs and ran 4 different varieties. The first thing I noticed was this product looked very similar to the regular substrate, same look but appeared to be little darker and actually more dense. I cut the bag open and yes, I can definitely smell that it is different. There was zero manure smell, but more of a earthy soil smell rather than manure or coco coir. The hand feel was great, I felt that this was slightly more hydrated or possibly because it was denser. I mixed it all up with my spawn bags and did the same technique I always do.
A few days later I immediately noticed that I was seeing more white mycelium poking through earlier than normal. I can tell something was different. After 7 days, 3/4 tubs were almost fully colonized! I wanted to post this review now that my first tub and flush is complete. I can say that yes, this is good stuff. Mushrooms really seem to like it. I did not do a side-by-side comparison but one thing I noticed was I got very few aborts, almost all my pins turned into full mushrooms and I had a solid canopy. I still have 3 more tubs that are also looking really good. I can't comment on the "flavor" potency but from what I've read that should be enhanced. Overall I would agree this is really good product and it basically comes down to whether you can afford the extra money. I can't give it less than 5-stars but I would say I will probably continue to buy the regular select bulk substrate and try mixing one bag of this in a few tubs, maybe splurge and buy this when I have extra cash.
Shipping was fast.Everything was packaged well.I love the kit so much I ordered another the following week.And I loved both so well a week later im ordering 2 more😁.I love the size and quality is good.I definitely plan on doing much more business with Midwest Grow Kits.Thanks guys.Happy Shroomin😇
I'm a first time grower and so glad I bought this. I received it and set it up exactly a week ago and harvested my first flush this morning. Keeping everything at perfect conditions makes the experience of growing fast and easy. I can see a lot of activity inside my slower blocks too!
An older spore syringe still started in about a weeks time. These are the best jars on the market.
Do yourself a favor and buy this product with and or for the grow. So simple and works so well. Compared to setting up a random of your own most likely. Have only used the whole set once so far ,and am already much happier than using a random other product I already have used in the past.
24 is working well I think I shook the 32 I got too much but I sure adore my jars guaranteed to not turn to mush.
It been 10 days and everything looks good so far. Plus I'm growing a strain that takes a while to grow. I would definitely buy again!
The fan is small and quiet. Light weight, I can hang it any where around the tent. It helps keep air flowing in and out. My mushrooms are growing fast and ready to harvest. I love it! Definitely buy it again. Thank you!
Cannot say enough good things about the support here! They have multiple technicians that know these units inside and out. I had an issue with a breaker in my laundry room and I thought it was something wrong with the sterilizer. Brian walked me through steps to figure out my panel and it was merely a bad breaker in my old panel. Love the sterilizer and it really changed my life coming from a Bubba Barrel. No more contam!! I can set it to run at night and wake up and unload!
My order came faster than I thought i would i slap punches some spawn grain and other products so far ive been happ wit everything ive received keep up the good work
Ordered 5-Tier, very easy set up. I searched YouTube videos to make sure I set it up correctly. Perfect size, exactly what I was looking for. My mushrooms started coming out. Highly recommended
Jars came as described. I would buy again.
Well I bought one and a week later I bought another one and a week after that I bought another 😂 so I have 3 stacked up on each other and they work amazing!
For the price I thought it was going to be small, but its not. Its a great deal. I grow for personal and it gets the job done. There's more than enough space for what I need it for. I included a picture with a cigarette light for a frame of reference to the size
Awesome and easy to setup/understand how everything works
