Description
Description
Blue Myco commercial autoclaves are high-capacity steam sterilizers built for professional mushroom farms, mycology labs, and commercial substrate production. Available in 310L, 550L, and 1180L chamber sizes, each unit sterilizes 450 to 1,500 pounds of grain per cycle at a true 14.7 PSI — the throughput of roughly 40 pressure cookers, in a footprint that fits a garage or compact production room.

Which Commercial Autoclave Size Do You Need?
B-310L — the entry point into commercial sterilization. A double-decker chamber that handles 150 three-pound grain bags per run in a footprint under three feet wide. Right for farms currently juggling four to six pressure cookers or a vertical autoclave that has become the bottleneck.
B-550L — a single-deck chamber with the widest opening in the lineup, which makes loading and stacking bulk substrate blocks easier than the double-deckers. 235 bags per run. The best fit for most farms scaling from hobby volume into steady weekly production.
B-1180L — 500 bags and 1,500 pounds of grain per cycle. This is production-line capacity. At 101 inches tall it needs real ceiling height and a dedicated 70A circuit, so plan the room before you plan the purchase.
How These Compare to Pressure Cookers and Vertical Autoclaves
Most growers start with stovetop pressure cookers, then move to a vertical 150L or 200L unit as volume grows. Those are excellent for small-scale work. The gap opens above that: once you need to reliably hold 15 PSI at real volume, the conventional answer is an industrial autoclave, and many of those systems run well past $100,000.
Blue Myco fills that gap. These are portable commercial sterilizers that reach the same working pressure at a fraction of industrial cost, and they pasteurize and sterilize in the same chamber — so one machine covers both grain spawn and bulk substrate.

Frequently Asked Questions
What size commercial mushroom autoclave do I need?
Work backward from weekly grain volume. The 310L handles 450 lbs per cycle, the 550L 700 lbs, and the 1180L 1,500 lbs. With a 3.5 to 4 hour cycle you can typically get two runs per shift, so a 550L running twice a day covers roughly 1,400 lbs of grain daily. Buy for the volume you expect in 12 months, not the volume you have today — but do not buy capacity you will not use regularly, because a half-loaded chamber costs the same in power and time as a full one.
How is a commercial autoclave different from a pressure cooker?
Scale and consistency. A pressure cooker sterilizes a handful of jars or bags; these chambers hold 150 to 500 bags. More importantly, a commercial autoclave holds pressure and temperature under automated control with safety valves, low-water shutoff, and a programmable timer, so every cycle is repeatable. That repeatability is what eliminates the contamination variance you get from running multiple cookers by hand.
What electrical service do these require?
All models run on 220V. The 310L draws 9kW on a 50A circuit, the 550L 13.5kW on 50A, and the 1180L 13.5kW on 70A. Each model can also be configured for 3-phase electric. Have an electrician confirm your available service before ordering.
Can these sterilize bulk substrate as well as grain?
Yes. The same chamber pasteurizes and sterilizes, so you can run manure-based and wood-based bulk substrate alongside your grain spawn program without a second machine. The 550L single-deck chamber has the widest opening, which makes loading large substrate blocks easier than the double-decker models.
Do these actually reach 15 PSI?
Yes. Operating pressure is 14.7 PSI with a 45 PSI maximum rating. Time to reach operating pressure is 60 minutes on the 310L, 80 on the 550L, and 90 on the 1180L. This is the specification that separates a true commercial autoclave from oversized pasteurizers that stall out below 15 PSI.
Can I see one in person before buying?
Yes. We run these units at our own facility in Woodstock, Illinois and welcome appointments. Call (815) 333-6716 or email jeff@midwestgrowkits.com to schedule a visit and see a full cycle run.

Red sorghum sprouts offers higher antioxidant levels, easier digestion, and rich plant nutrients. Sprouting red sorghum improves its health value by increasing beneficial compounds and reducing barriers to absorbing its nutrients.
Mycelium shot through the casing layer in 2 days. GtPlat. 2/1
Outstanding materials at the lowest cost I could find. Would not pass up this offer if you're serious about growing
This definitely does the job and it’s an excellent product for the price. It took be about 2 hours to set it up and make all the necessary modifications. The FAN solution that comes with it is at best temporary but it will due the job until you can save up for a better fan.
I plan to make tinctures for the messed up nerves in my arms, and other chronic pain bs. Don't want to support too many opportunistic companies, so I just chose the source and be patient. Holistic care and responsibility is a game of patience and understanding. I appreciate your services! Be well, do good! Try to waste less. Oh, the small black gloves are useless unless you have the hands of a small child.😅
Just stirred it, don't worry🫠no stir bars or magnets have ever been needed here.
Awesome growth 10 days after inoculation. Very happy! Would recommend this priduct and this company!
Working good. Lights my closet just enough for the environment I need! Thanks!
It's started good. Let's hope it continues to grow so I can break a shake it!
Bought the 3-Pack Premium Quick-Colonizing 5-grain Jar (32oz) and inoculated 9 days ago. Love it! Colonization quick and clean. Highly recommend!
So when i got this i was worried because of past experiences. Leave it up to midwest to be nice a patient with me. The team at bonsai gives great support . This flow hood is meant to run a little higher than normal clean room standards because most people need this working from home . This thing is nice and laminar. Very inform . With a speed contoller i average about .45 m/s across the face. It passed everyone one of my agar grid tests . Which blows my mind becuase i ran it through three diffrent 30 mins agar grid tests . Ive used a few flow hoods and this one is my favorite . Perfect for any home or small buisness.
"Upgraded to the MycoClimate 44Q and the difference in consistency is night and day. The dual-chamber water-bath heating keeps temperatures rock-solid without drying out the substrate like standard heating mats do, and the automated HEPA air pump takes all the stress out of fresh air exchange—even tucked away inside a closet.
i saw germination in my jar within 2-4 days!! I ordered a 3 pack and i injected 3 different strains and they are all colonizing and germinating very rapidly i see ne difference in rate of germination for genetics they are all moving about the same speed im happy with my purchase!
100% RELIABLE EVERY TIME I LOVE YOU MIDWEST THANL YOU TEAM
Reliable and I know what I am getting. Pretty quick colonization.
I got the grow bag instead of jars this time because I am not interested in the steps of the jars.
Been there done that.
I am not an expert🤓 but now I have enough knowledge and experience to call myself an apprentice.
The thrill of the process is gone. Just give me the dam mushrooms.
I am hurry up and waiting😉.
Seems to be working is all I have to say at this point day 7. The green is reflection not mold.
