Presto 23 Quart Pressure Cooker/Sterilizer - Model 01781

I live in a drier part of the country and decided to add these to my tubs. Glad I did. They come in handy especially after the first flush. I always notice my tubs get little dry after they fully colonize and I don't get the amount of droplets like when you first mix it all up. I sometimes over-mist also, these gauges let me see exactly when to mist and when to skip it.

Snaps right in and works like a champ!

Where were these years ago?? I love these little things! I can easily tell when my tub is starting to get too dry and when I need to mist. I could have saved some tubs if I had this in the past!

I've spoke with a few people here before buying and all my questions were immediately answered. Since they run both the 150L and the 200L, these guys are great. They helped me figure out the best sterilizing times with my particular grains I am running and how to stack my bags to maximize space. Whenever I call I am transferred to a tech and someone almost always answers and is very willing to spend time on the phone. These guys have the best price and best service. I will be back again soon for another unit next month.

I bought one about 19 months ago, out of the warranty period, was moving locations and something must have come loose inside during the move. I called Midwest and spoke with Brian and Jay about 3 times last week and they were so helpful. Brian walked me through on a Facetime call and he noticed a wire was hanging where it wasnt supposed to be. I plugged it back in and it was running like new again, just want to let you guys know how much time you saved me and anyone on the fence about buying any autoclave from these guys should pull the trigger, the tech support alone is worth it. I can't say enough about their team but want to share this experience. Peace and love guys! - Ray

Very easy to operate with plenty of room for my bags. Actually this machine can fit a little more than I expected! Run times are a little longer to get to pressure when I max it out but it sterilized like it should and am seeing zero contam in my bags! I have it hooked up to a 40AMP breaker in my garage and even though it draws 36AMPS, that breaker works fine!

I was impressed with how easy this thing was to put together—took me less than fifteen minutes, and the step-by-step instructions were clear. The vinyl and zippers feel tough right out of the box, and once I flipped on the humidifier and fan, it was obvious the design was solid. The digital humidity control held steady the whole time, so I didn’t have to keep checking in. (The controller is easy to use, but just make sure you are in the right mode, you can switch between Humidification and De-Humidification.) Within 9 days I had strong, even flushes across different varieties. For a compact setup, it runs like pro gear and makes growing a lot simpler. For the money you can't come close! 5*+

The Tabletop Ecosphere made dialing in conditions stupid easy. I had my grass-loving mushrooms fruiting in just a few days after moving them over to this setup, literally without babysitting humidity or airflow. Setup was quick, the chamber’s solid, and it fits right on my counter. For mushies that a tub or big tent wont work, it’s hands-down the easiest way I’ve grown these so far.

I wasn’t sure what to expect at first, but the Tabletop Ecosphere surprised me. Putting it together was simple, and I didn’t run into any confusing steps. Once running, the humidity stayed right where it needed to be, and I didn’t have to constantly mess with it. Within just a few days I had pins forming, and the mushrooms grew out strong and healthy. It’s not a big setup, but for the amount I wanted to grow, the size is perfect. I like that it doesn’t take up much space—it just sits neatly on a counter and does its job. For me, it took a lot of the stress out of growing and made the process way smoother than trying to manage everything manually.

Chestnut is a "Shy" mushroom.. It likes to just hang out until its ready to "pop", but when it does, it produces a TON of mushrooms. One of the best stir fry mushrooms I have ever tasted. Just give this guy some time and it will eventually come around!

I love the fact that I never have to buy petri dishes again! I throw my spent plates in the Dishwasher, then in my Presto Pressure cooker for 20 mins and they are like new! Zero contam!

Colonized my grain spawn quickly and incoulated a 2'x3' area under my pine tree in a bed in my yard and just looked today and I can see little pins! This process takes awhile but I am coming back here 6 months later to post this!

I have been looking for something like this for years! This really makes the process contam proof! Willy Myco mentioned this in a Youtube Video and he was on point! I can now easily pull liquid anytime without a flowhood!

Comes with everything you need and fits on my Quart jars perfectly. I actually leave the middle hole capped and use the deep draw needle to suck up LC when I need it. I think its much easier than going through the injection port many times and leaving room for contam to enter.
