02 —What growers say.

★★★★★
After lousy experiences with North Spore and others (contaminated spawn/growkits), I tried Southwest and I'm sticking with them. Decided to try a Lion's Mane grow kit, and I'm beyond satisfied. Whatever strain it is, it's yielding dense, white, tasty fruiting bodies as hoped, and better than any others I've tried to grow.

I've tested grow bags from North Spore and all the top rated brands on Amazon - nothing can compare to these grow bags! The size, health, and yield I got from my three SWM grow kits are absolutely amazing. I will be buying exclusively from SWM going forward.

Mike has the best LC, hands down. He has cultivated the most prosperous strains over years of hard work and dedication. Look no further for your LC needs.

I ordered all of their liquid culture strains and they were all spot on. I transfer all of my liquid culture to agar to check for contaminants and none. The proof is in the picture. Great job Guys!

I recently used the grain spawn I ordered and was very impressed by the quality and quantity of mushrooms I was able to harvest. Thank you so much Mike for calling me personally to ensure I was getting what I need to start up my farm. You truly are passionate about what you're doing.

Southwest Mushroom has such a commitment to high quality grow practices and processing for powder (using heat extraction). I pay more to get more value and quality!

03 —Questions.

Everything you need to know before you buy. If something isn't covered here, email orders@michaelcrowemycology.com and you'll get a real answer from the farm.

What format are the SOPs delivered in? +
Every SOP is a PDF document. You download it immediately after checkout, and a copy is also emailed to you. The PDFs are designed for both screen reading and printing. The Lion's Mane flagship is 175 pages; the others are similarly detailed.
How fast do I get my protocols? +
Instantly. The download link appears on the confirmation page the moment your payment is processed, and a second copy lands in your email within seconds. No shipping, no waiting. Growers on six continents run these SOPs.
Are these beginner-friendly or advanced? +
Both. Each SOP starts with the fundamentals (substrate ratios, sterilization, environment) and builds to commercial-scale production details (yield benchmarks, flush scheduling, contamination economics). A home grower can follow the early sections; a commercial operator gets the full production-floor playbook.
What if I don't find them useful? +
You have 30 days to decide. If the protocols aren't the most useful cultivation documents you own, reply to your download email within 30 days for a full refund. No forms, no friction. We'd rather have a happy non-customer than a reluctant one.
Can I print and share these? +
Print them for your own use on the farm, yes. Share them with your team at your facility, yes. Resell, redistribute, or post them online, no. Each PDF is licensed to the buyer for operational use at their own grow operation.
Do the protocols cover contamination? +
Extensively. Contamination identification, prevention protocols, and recovery procedures are built into every SOP. These are the same procedures we use to keep a commercial floor clean. You'll learn what green mold looks like at hour 12, not day 5.
Why should I trust these over free YouTube videos? +
The YouTube channel (195K growers) is the preview. The SOPs are the complete operating procedure: exact substrate formulas, fruiting parameters with numbers, yield benchmarks you can hold a crop against, and the troubleshooting you only learn by running thousands of blocks. Free content shows you what's possible. The SOPs tell you exactly how to do it.

The Method

Most cultivation advice is hobbyist folklore. These are operating procedures.

Every protocol here was run, measured, and corrected on a commercial floor — not paraphrased from forums. Substrate formulas with ratios. Fruiting parameters with numbers. Yield benchmarks you can hold a crop against. The same documents we use to train growers and keep a farm consistent.
