Ultimate ½ Pint Substrate Jars (6-Pack)
The Original PF-Tek Method—Perfected Over 15 Years
Still the fastest and easiest way to grow mushrooms, our Ultimate ½ Pint Substrate Jars are built on the time-tested PF-Tek method using premium brown rice flour. With over a decade of refinement and thousands of satisfied growers, these jars remain a top choice for beginners and seasoned cultivators alike.
What’s Inside Each Jar:
- Natural Organic Brown Rice Flour
- Vermiculite
- Mineral Water
- Liquid Worm Castings
- Bee Pollen Boost for enhanced growth
- Sterilized for 120 Minutes in a commercial autoclave—ready to use out of the box
Each 8oz jar is topped with a dry vermiculite barrier and sealed with a lid pre-drilled with four inoculation holes. Your jars are handmade fresh the day your kit ships, then securely foil-wrapped and bubble-packed for safe delivery.
Why Our Jars Stand Out:
- Fastest Colonization Speeds – Achieve visible results faster than standard BRF jars.
- Superior Ingredients – Our proprietary blend produces larger mushrooms and healthier mycelium.
- Time-Tested Quality – Trusted by repeat customers for over a decade.
- Perfectly Prepped – Just add your favorite spores or liquid culture and incubate.
Includes:
- 6x Fully sterilized ½ pint substrate jars
- Aluminum foil wrapped and bubble protected for shipping security
- Fresh-made jars with premium-grade ingredients and unmatched consistency
Ideal For:
- Beginners learning with PF-Tek
- Researchers seeking high-quality sterile substrate
- Anyone looking to simplify their first grow without sacrificing results
Let customers speak for us
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
Excellent product with 0% contamination. Amazing customer service.
Jars are working fine. The 5 lb bag got contaminated twice for the 44q monotub.got a replacement, but the 2nd one nothing.
Excellent service and great response time well worth your time to deal with this company
Bought 5 grain jar 32 oz innoculated with spores July 11th 30days later August 11th fully colonized mix with 5 lbs.casing mix put in 28qt monotub many mushrooms growing also I bought air filter patches and eco cleanse anti mold for misting shipping was super fast as always every thing arrived securely packaged
I’ve used these several times. I’ve never needed to do huge grows like some people do. These colonize fast with liquid cultures and out put nice flushes. I even resoaked them for a second flush.
Man, this kit just makes life easy. Everything came fresh, clean, and ready to use — no stressing, no sketchy prep work, just straight to growing. The totes are low-key perfect for keeping things smooth, and the heater keeps the temps steady without me having to babysit. Setup was quick, and the instructions walked me through without any guesswork.
What really hit me is how stress-free it is. Mycelium took off, no contamination, and it’s been all good vibes watching it do its thing. If you want to keep it simple but still get solid results, this kit’s the way to go. Midwest kept it real with this one — chill, reliable, and worth every penny. ⭐⭐⭐⭐⭐
The Tabletop Ecosphere was straightforward to set up, with clear instructions that made the process quick and hassle-free. The build quality feels solid, and the automatic humidity control worked exactly as described, keeping conditions steady without much attention on my part. I was able to start fruiting my mushrooms within days, and the results were healthy and consistent. While it’s not a huge chamber, it’s perfect for small-batch grows and fits nicely on a countertop or shelf. Overall, it’s a reliable and well-designed unit that makes mushroom cultivation much easier.
Love it! High Quality - Doesnt fade!
I always air-dry my mushies with a fan, I was looking for something besides plates to use when harvesting my tubs. This tray is perfect, when you place this tray on a flat surface like a counter the bottom can still get air and my fan works perfect drying all parts of the mushrooms without having to rotate everything as often. This is a great buy if you already buying other stuff in your cart as the Free Shipping makes this a deal!
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.
Me…I’m the dummy. I struggled with maintaining humidity in my diy monotubs. The holes were never the right size or in the right place. Not with these. Perfect humidity. And I love the clamps. It’s like a child proof lock for me, warning me not to open until ready! Very well made. I wish I had found these sooner.
