Always have a backup hole. Words of wisdom
Hey now! 😆
A big Thank you for sharing all of your sourced materials. I know this takes a lot of time and effort! You've saved me hours of sourcing..
Good to see you back again Eric!
Nice work Eric! Thanks again for sharing
Can you tell me more about how you fold the bags? I'm having trouble getting clear answers about it. Thanks for your videos!
6:20 "It will plug that hole and make a bomb" :D This seems like an important step
a fairly terrifying thought
Hey Eric, I get your explanation. Thanks, do you have any written plans????
And where do you get a stainless 55 gal drum?
Thanks in advance!

Hi. 75-80 degrees is enough to sterilize sawdust, you can simply fill in 60-80 sawdust with hot water, and put them in a warmed place and when you finish forming the packages, the first packages will cool down and you can add mycelium, I have never had any harmful spores. tested 5-10 pieces
75-80 Celsius?
I hate to keep being a wet blanket but having your flow boxes in a humidified area is a very very bad idea they're going to go bad so fast. We had to dramatically dehumidifier one of our labs in Ann Arbor Michigan because it was ruining flow Hood filters
Its not humid in there, the steamers are on PID's the only time it gets humid is unloading then the bags dry quick.
@@MyersMushroomsFarms I'm glad that it's under control that's a good thing but I don't understand how being in a PID can have anything to do with it??? Pids are basically feedback loops the control temperature or humidity or whatever.I use pids from my days in the robotics industry I have a whole box of them. So I basically know what they do it how they do it. But you are steamers running in a PID would have nothing to do with how humid he gets in the general area of the steamer. Unless you mean not a lot of extra steam escapes because it's just kept in a balanced rate??? even then I don't really understand the statement
I'm not trying to be an asshole I just don't understand honestly.
I think I'm going to build one of these myself but base it off of temperature it is simple PID with a t type probe.
@@ClownWhisper pid set 5F below boiling means very little steam escapes
How you control the temp?
You should have it on a PID temp controller. You're just blasting heat out through the steam outlet which is being lost. You just only cycle it on as needed to maintain the temp at the top of the chamber.
It doesn't matter if you need the humidity. A high pressure mister system would be much more efficient than boiling huge amounts of water.
Yes we have ours on a digital time temperature PID.
Smart Myers 👍🏼 how much was the expense of your total diy steamer
Just getting to the point where I need to sterilize bigger loads.. Do these steamers cost a bunch on electricity?
where does the inkbird come into play? i dont see any probes in your barrel.
Do you know the barrel thickness?
@Myers Mushroom Farms : You mentioned that you wished you could find that high temp hose at 6' long. Why don't you just buy a couple brass replacement ends and cut down the hose you currently have ?
I did find em, I use stainless steel braided washer hoses now.
Does it work for grain
Thanks for the shearing!
Question: Is it necessary the barrel to be stainless steel?
If you want it to last. Plastics will hold up for a bit but I hear they warp after time. Plus if you go with steel you can eventually modify to push 1-2 psi
Hi Eric! I'm thinking about building one of these, but I don't quite understand the 5gal bucket lid under the barrel lid? It's used to create a spacer between the bags and the barrel lid vent, or am I wrong?
your correct my friend, look luck :)
Cold in El Paso? I worked in Las Cruces in the winter and I have never felt cold even in the middle of the night in the middle of the desert I mean you get a little chill once in awhile but nothing cold then again I'm from Michigan LOL
it gets down to 20F here and im exchanging outside air every 6 mins.
@@MyersMushroomsFarms wow nice that's weird I was there in the winter I think I was in there February 8th and I never felt any coldness I heard it frosted in the desert but I didn't experience it and I went on some real early morning hides behind the organ mountains big mistake I was tracked by a mountain lion it came down it was about three football fields away from me I was watching it with my binoculars and it was headed towards me slowly I'm lucky to be alive
Hi please respond do i need float valve or can i just fill with water like pressure cooker I dont have water pressure at my farm yet
Because of the long cooking time you can’t put enough water in. And opening to fill up would open to air and contamination ... self filling means it can safely refill on its own when needed and still remain sealed
@@perfectstranger232 What if you have a designated boiler that pumps steam into a separate barrel? How much water do you think you would need to run a 24 hour cycle?
Have you had issues with the styrofoam insulation boards melting? Dow says these blue insulation boards are only rated to 165F
Only if steam contacts it.
Myers why 19psi isn’t better 15psi is there much of a huge difference on getting more flush’s?
If ur talking about sterilizing I believe conventional wisdom is for every 1 additional psi you can lower sterilization time by 10 minutes
boom
7:11 what kind of bags are those? do you use this system for grain or bulk ?
I guess they're unicorn grow bags, i sometimes use them they're good, check them out on Instagram @unicorn grow bags
this is for bulk substrate, use pressure cookers for your grain spawn bags
is there anny problems if i used a copper cylinder
should work fine.
Are you selling these instruments and what's the price? I'd like to order several for my farm.
yes bubbasbarrels is manufacturing them, check the link in the description
It's possible to construct something like that with an old oil barrel?
these are actually already repurposed - so yes as long as it's clean and in great condition and doesn't have any residual chemicals or etc on the inside
where did you get the flow vale
all the parts are in my kit link in the description
Surely doing this by electricity is alot more costly than propane ?
absolutely not. Propane is more expensive, and dangerous.
@@MyersMushroomsFarms wow I'm surprised. That's great because alot easier to do inside as well. Thanks man
can you sterlize grain jars like this?
sure
@@KevinLaPage-ff6bj have you done it?
@@xstnzsound1069 I do not have this large of a setup. However if you cannot increase the temp through pressure as a pressure canner you would just increase the duration of time the spawn jars are in the barrel. Hopefully the vid creator will weigh in for you on this. Take care
yes, technically you can but i would rely on a pressure cooker for that. i can fit 10 qt jars or 6 5lb large unicorn bags in 1 $160 presto 23 quart PC. I'm in the middle of building one of these large 55 gallon sterilizers but it's for substrate bags not grain jars.
Man, I don't get it. I find all these videos about the steamer build, but never heard you talk about the fundamental principle. How's this system different from a pressure cooker. How do the pressure amounts and temperatures compare to each other? Why does this one take a full day for a cycle? I guess this one uses less pressure, but can get up just to the right temperature for sterilization.
Sterilization is a time temperature formula for lethality. Lower temps just take longer. This were shooting for 200f for 4-6 hrs while an autoclave is doing 240f for 20 min.
@@MyersMushroomsFarms Awesome! Thanks a lot!
@@MyersMushroomsFarms 4-6 hours? i thought it was 20-24 depending on capacity and heating element/power supply?? you really confused me with the 4-6 hour thing. could you please elaborate on what you meant by that? i'm halfway done building my own, can't wait till its done. just finished the PID now onto the barrel. and also thank you for all your videos and knowledge you have shared with the myco community.
@@siandrusko9073 total run time is longer but core temps 4-6 hrs at 195-200f. it takes anywhere from 8-20 hrs for the cores to hit that.
So you aren't sterilizing under pressure?
atmospheric steam, its all you need
@@MyersMushroomsFarms even for your grain or just sawdyst spawn and bulk sub?
I don't understand the oxidized layer part I'm an organic chemist and stainless steel should entrust in just hot water anyway. I mean I understand oxidation will inhibit rust development but if it's a stainless food-grade type of table it should never rust with just hot water introduction unless you seriously got it red hot at one time
You are a chemist, not a machinist. Look it up, its a thing. I learned it from welding SS and brewing where rust is a big deal on vessels. When welders weld SS they etch it with acid. Passivation of SS look it up
@@MyersMushroomsFarms funny thing I am a machinist the chemistry is just a hobby well Machining is more of a serious hobby and a money-making thing. I'm not the master machinist per se I've just been working with metal for many many many years. I have a couple of meals I am hurting to lathe of an old Logan I'm getting a monarch pretty soon.
@@MyersMushroomsFarms will ya I didn't realize you got it red hot like I said in my original post if it was just cut on a bandsaw they probably would not ever rust unless it was heated up a lot. I work with 304 stainless continuously every single day for a little side money so I do have some experience with it. But absolutely you heat it up with a torch or a welder and it's going to rust like hell I didn't realize. Again I'm sorry I'm not trying to be a dick LOL just trying to understand
@@MyersMushroomsFarms can I ask how much you paid for your drum I'm having a hard time finding one. I would really like to do one slightly smaller perhaps 30 gallon..... While I'm sitting here writing this I'm thinking I have to stainless steel kegs in the basement I most certainly could use one of those and fashion good lid for it
@@ClownWhisper just drilling and cutting the SS with an angle grinder heats the metal red hot on the cut edge. I paid like 800 fot my 85 from bubbas barrels. having ss makes it last forever and not get rusty, stays nice and sterile inside.
Dude, you need to stop fucking with the comments on your product list on your kit.co website. One guy commented with the hole punch that it didn’t work-the hard way, and i can’t even make a comment. I don’t know where the fuck you’re from, but i correct my mistakes to 100%. I thought that was the essence of your core principles. Integrity first, Service before self, Excellence in all we do. I guess that shit doesn’t apply since you’re out and not wearing ABUs/stripes anymore on your product list for those that dont want to pay for the over priced bubbas barrels.
