Do I need really need a PC?
    #23745554 - 10/17/16 01:03 PM (7 years, 3 months ago)

I'm trying to inoculate half pint jars of rye berries with LC (clean). However I've been reading that steam sterilization doesn't kill endospores therefore I need a PC for sterilization if I'm trying to inoculate grains. Not sure if this is actually true since I sterilized my BRF jars just fine using steam before incoculation with no contams whatsoever

So any opinions on this? Or should I just go ahead and steam sterilize and shoot em up?

Some have steamed them with success, but for 8 hours or more. Some say brown rice contains little or no endospores and is more selective about what grows on it (cue shitstorm).

I have tried that at least 20x w/o success, the best I had was on 6hrs and even then by wk 3 the contams started.
I have done well with flax seeds, steamed them loose in a basket(to hydrate), then jar'd them and steamed for 90mins with good success but it will not break up like berries so you may as well stay with BRF..
Popcorn works well on a 2hr steam after hydrating and breaks up well...

Every time I go to Walmart I see pressure cookers for 28$. Just get a cheap one. I personally wouldn't want to waste all the time and resources for something that may or may not sterilize them.

Pressure cooking makes it easier with small amounts. Streaming makes sense for farms because doing 200lbs of grains and 40 sub blocks is needed for a day production. Get the cheap 70 dallor ones at walmart. As to ms being better then lc is easy. Lc saves time if clean and full of myc. Most sugar lc can't contain more then 12.3% by volume. Most times you can't ready get lc perfectly clean without agar and other thing you need higher psi sterile stuff. The result is myc growing in your liquid with heavt amounts of bacterial life. You shoot up with the bacterial life inside the lc into grains. Boom of bacterial life in grain spawn making myc weaker and slower growth vs even spores water with light bacteria infection. Where once the spores germinate they soon out run the bacterial life.

When i sterilize i just put a towel on the bottom of a pot, pour enough water to cover the jars 30-40%, put on the lid an boil for 1 hour.
After the jars has cooled down i inoculate them and that is all.

I have done this every time and only had 1 contaminated jar during incubation.

Highly recommend this method due to itยดs simplicity and speed.

Good luck with your growing :smile:

Just'd like to bump this. ended up buying a PC for about $100. Sterilizes BRF rye , manure, peat, etc just fine in as little as 15 mins (PSI ~ 13). I grow everything starting with PF tek, not contams so far in any jars I've done. PC definitely worth it.

Boiling definitely does the job for the most part, rye grain included. I believe the most important part is  sterility during inoculation

Also why I like LC. If it's done right it will be sterile and also hydrate substrate when u inoculate.

I need a third hand to facepalm right now......

We say PC BRF jars for 60 minutes and grains for 90 minutes(and these are minimums) because thats how long it takes the center of the substrate jars to come to temperature to ensure proper sterilization and to ensure the death of endospores.

And please explain to me how anything can dry out when the PC is filled with steam....I am dying to hear this one. Me and everyone else who has been doing it for decades must not know that our jars are dried out after 2 hours of sterilization in a 100% RH environment.....I guess I missed that part in basic logic.

After my first steam sterilizer run cooking 24 hours that top grains dried out in all jars in all 4 rows. So it can dry out while cooking. Point being it needs to be cooked proper timed to kill everything even with pf cakes. I don't know why you hate lc pussyfart? If it's clean being knocked up with agar there is nothing faster way off production of clean cultures.

I feel like no one mentioned you can boil/steam brf jars because the fact that there are no endospores there whereas grains do and it takes longer to kill them, hence longer pc time. Like the tc said, those are minimum times. I did read somewhere that you can boil grain for x amount of minutes 3 days in a row and that works for those without a pc. And just for fun I experimented with boiling time on the pf jars, I got away with 25 mins and had great success (which I do not recommend, just follow the tek). As far as drying out, I've thankfully never experienced that.

As I see it a syringe from a vendor is far more likely to be contaminated than a LC I've made myself. Would think that a TC as yourself would feel the same so that's why I assume you make your own prints in a sterile environment.

Would you recommend a noob to shoot up their grains with a syringe from a vendor? Cuz that's how I would have interpreted your post a couple of years ago..

What are you asking?

The reason why I feel MS is better than LC is because in a spore syringe, if there's bacteria it doesn't just multiply rapidly and take over all the inoculant. A spore syringe can have a few bacterial drops, but not every drop will be contaminated. An LC is pretty much either clean or fucked. And it can be hard for people to tell if it's bacterial. If you don't have agar, 100% MS > grains is much better than MS > LC > grains.

I'm sure people can make clean LCs with spores, but the point is that unless you're inoculating with agar, it's more risky than just spores by themselves.

Wrong. It most certainly does happen. Learn some thermodynamics.

EDIT: Yet I'm sure that the amount of water in substrate before PCing and the composition of the substrate are a major factor in whether or not it loses moisture. Think about what happens when your PC shuts off. The jars retain heat way longer than the surrounding atmosphere within the PC. Now think about the relationship between cold and hot air.

i just got done pcing about 40lbs of birdseed over 3days. its totally awesome.

it all is pressure cooked at 15 psi for 2hours. this is a industry standard that
people do everyday here all day 365 for 20years.


not an outlandish opinion.

Well it goes without being said that a larger amount of substrate requires a longer sterilization time .... Now that is common logic. No need to PC half pint BRF tek jars for over an hour, what a waste of time lol

That it is indeed possible to dry out substrate by over PCing. And I don't "think" that I have sterilized grains, it addition to basically anything else that would be sterilized , I HAVE sterilized them in that timeframe and not once had issues with contamination.

Not pulling anyone's leg here. Just stating facts.

As for my point in this thread, it's that you really don't need to PC for as long as most of the teks on these threads say.

Oh don't worry, I'll keep y'all updated. By the way I'm not trying to argue with anyone. Of course I want to hear the input of others, that's why I'm on these threads.

Ironically, I do feel as if some people posting here suffer from some minor cognitive dissonance.:eek:

what southpaw is basically saying is that since the outside of the grain
was at temp for a few minutes it should kill everything.

but thats like saying i cooked you rice to eat but only the outside. the inside
of the rice is still hard.

Fair enough, sounds like a good experiment for the sake of science.

I've done coir monotubs (bulk sub bucket pasteurized...), cube cakes, pf tek manure jars for pan cyan, all sterilized for no more than 30 mins with the exception of my manure jars at 45 mins. The manure got dried out in the PC, like a crispy & brittle cake. Let me repeat... these were all more than successful grows.






And I don't disappear. I am always lurkin :wink:

Btw pics were requested and here they are :smile:



Thats pan cyan LC in a 50/50 honey maple ratio. Sterilized 30m in PC. There's barely any liquid left in the jar yet I'm surprised at how thick the myc has become. Hasn't been in the fridge yet.



First pinset on my latest grow. 30 min pasteurized spawn (dehydrated manure, small amount of gypsum & unspent coffee, coarse verm) 15 min pasteurized bulk sub (just plain dehydrated manure with verm).

NOTE: Before inoculating ANYTHING with the LC I always make sure there is distinguishable and thick myc. Give your LC a couple weeks of growth before using it.

I neglected these for a few days so they became dry. Applied a casing layer as soon as I could (thin layer of crushed dolomitic lime, peat, coarse verm; sprinkled fine verm on top) and peeled away the sides of the tray away from the myc and funneled some water underneath. I'm aware this could cause side pinning but don't really care. Next day I saw these pins.

At this point I also set a space heater, fluorescent light, and cool mist humidifier to a 2hr on/off cycle with a slightly cracked window nearby.



Zoomed out



These 4 trays weren't fully colonized, about a week behind the first 2, when I cased them. I probably should have waited but did it all at once. However not too worried and will sprinkle some more fine verm on top in a few days.



My first BRF jars as a "noob." They came out just fine, despite the fact that they were only PCed for 30m.



And last but not least my latest batch of cubes put in a FC a few days ago. Only doing these instead of a monotub because they smell nice.

how can the perlite function when its in a bag like that? it cant btw.

wait..wait.. you were asking about needing a pc? and people said no you can steam with pf..
then we went around in a circle jerk and now your back at a pf cake you PCed for 30min?

wtf is the point of this thread dude.:confused:

Bag has pin holes in it, because I don't want wet perlite on my rug... And i think you mean what's the point of the fruiting chamber if there's a bag on the bottom? Either way the perlite does its job by retaining moisture, and I have plenty of ways of ensuring that the air doesn't become stagnant...

Besides that, my point is that I'm right about everything I've said so far, because it works :smile:

I will, I will jeez. What do u expect me to pull agar plates out of my @$$?

I'll put time stamps on the pics and everything when I get around to it. But at the same time agar is a bit different than rye, BRF, or manure. It's much more prone to contams. But I will try to do it as clean as I can.

As I mentioned before, the most important part to avoid contams is using proper sterilization techniques during inoculation and make sure u are inoculating with clean, strong myc. People on this forum seem to emphasize the step that involves PCing/steaming/doing whatever to your substrate is more important than that. I disagree, and I look forward to proving y'all wrong :evil:

Well, I've posted my results and I have no reason to lie to you.

I'll leave you with this.

Mushrooms are a natural phenomenon. There is no pasteurization process in nature. Consider evolution. Has anyone ever considered that over pasteurizing substrates could lead to a lower quality product over X length of time?

Have you ever seen the movie Bubble Boy?
Look forward to continuing this conversation.

Why do you like agar mushboy?
I think I already know the answer, but I am here to hear opinions.
For me, it's the ability you have to isolate strains... It is no doubt more precise than trying to use LC, but LC can still be used in the same way. If not much less efficient.

I agree a little bit my first 20 or so bacths of grain were pc for 90 mins instead of 2 hours or 2.5 hours. And they were sterilize enough to live with. Then i reliezied that advice changed for a reason. The stardred is 2 hours that kills 14% more endospores. Running a pc another hour on a 1000w stove or my case two pc then for hour is 15 cents. Isn't your piece of mind per grain run worth that to you. Since i swicthed over to two hours pc time I've only shut it off earlier once because i was passing out and re cooked it the next day.

Ok so heres a tek. You make agar plates and cook them 45 mins. You drop spores on them , you make tranfers until clean all in still air box. You tranfer clean into a cooked lc in still air boox. You prep grain, soaking 24 hours and drain to air dry 1 hour. You load up jars with aready made lids with ship and ge filter, cover in foil. Pc 2 hours at 15psi. Let cool down. Knock up sterility with syringes pc in same cycle and suck up lc. Inject into grain jar small amount. Repeat each day with new jars for new grain. Once colonized grain jara are done, mix coir in a bucket with water and then mix in grain and drump in pastic tote with lid cracked. Mist when needed, pick shrooms. Repeat, repeat, repeat. Done a tek for you

I just wanted an elaboration really..to clear things up for me as well as for others.

I assumed you were talking about LC's inoculated with a clean agar wedge, because MS syringe -> LC seems to be a certain way to fail and did not even occur to me as an alternative. Also the OP says his LC is clean.

Id never inoculate grains with a ms syringe, mainly because I don't like to wait for failure when I can wait for results, and wouldn't advocate it.

Cleaning ones inoculum is easy and encouraging people to use dirty inoculum seems to be a disfavour imo.

Yeah agar is the best but I assumed he didn't have agar, considering he didn't have a PC, and sounded like this was his first time doing grains.. I automatically don't trust anybody saying their LC is clean at that point. Even if it grew in brf.. bacteria doesn't affect brf nearly as bad as it does in grain spawn.

So yeah 1 drop of spores to grains is way better than a noob made LC, unless you can do agar well.. in which case for practice dropping wedges to grains and g2ging is IMO better for noobs than LC anyways.

I just took his word for the LC being clean. Perhaps I'm weird in that way, but others like me could misinterpret your wording and use ms to grains because a trusted cultivator said so.
I just care about the success people have with their cultivation. Wasn't out to get you personally. 

If what the OP said about his LC isn't the case I agree 100% with your reasoning.

Everyone says there of is clean until they see contam hit the jar or sub before it fruits. Even my last of big batch should have been clean since I used a clean wedge but all 49 jars knocked up were bacteria infection and made vingar smelling jars. Its best to test this out but until you see fruit your never 100% sure you did good. But same plate of agar I knocked up different jar of of at same time and spawn looks and smells fine. Lc is like a sword you live by Lc you die of lc

yep, the forum is full of non stop threads with people with useless dry grains after PCing for over 60mins, to think all these idiots had to do was reduce the time to 13mins. You'd think they would have seen all the other threads and know it would be a total failure.

I really share your confusion...

Let me clear that confusion for you mate. We pc for 90min because we want to raise the RH in the kitchen :grin:

Edit: and that's why AA pressure cookers suck :tongue:

:eek: the amount of people who post without reading the entire thread is fairly mind-boggling. Sometimes this place reminds me of the comments on Yahoo answers.

I never had a problem with dry grains, I presoak and cook. I'm talking about other types of materials.

Yeah agar is the best but I assumed he didn't have agar, considering he didn't have a PC, and sounded like this was his first time doing grains.. I automatically don't trust anybody saying their LC is clean at that point. Even if it grew in brf.. bacteria doesn't affect brf nearly as bad as it does in grain spawn.

So yeah 1 drop of spores to grains is way better than a noob made LC, unless you can do agar well.. in which case for practice dropping wedges to grains and g2ging is IMO better for noobs than LC anyways.




Also, being a noob and being stupid are two different things. My LC is clean. And i favor it over agar because I can literally have gallons of clean LC. Its so much more versatile. But agar is fun too. Id like to make some agar LC someday

I'm trying to inoculate half pint jars of rye berries with LC (clean). However I've been reading that steam sterilization doesn't kill endospores therefore I need a PC for sterilization if I'm trying to inoculate grains.

So any opinions on this? Or should I just go ahead and steam sterilize and shoot em up?

That was the original topic of the thread, which seems to have expanded to another question about sterilization time

If you are into this hobbie , i would get one for as cheap as they are personally , you could get an ok with a rubber seal and the seal will last awhile and the new ones are cheap and the PC will save you so much hassle worrying about contams during that phase

:whathesaid:

This thread has gotta be the biggest shit show I've seen in awhile.. either op is trolling, or has no idea how to articulate his thoughts properly..

Bumps this thread saying how he sterilizes for 15 minutes so things don't dry out, wonders why people even go above 1 hr, and inoculates with liquid to replace water lost, then explains how grains drying out isn't an issue?? Because the only thing you're supposed to be PCing longer than an hour is fuckin grains, IDK what other substrates you're even talking about.. if you mean pftek, 1 hour is plenty.. I'm not entirely sure about 15 minutes, but as long as all mold spores are dead, it really shouldn't be too hard either. No endospores to worry about..

And like I said you can inject pftek with a bacterial LC and it can grow just fine. Bacteria has an issue with pftek. Try inoccing with agar to 100% know if it's clean or not, the next best option would be grains, but that is nowhere near as good at identification as agar.

Other substrates like manure get pasteurized.. CVG can get sterilized or just hydrated so it's not like people even care about how long to sterilize that shit..

So what other substrates are getting PCd longer than 1 hour?

Let's not even get started on the clean LC with no proof.. and also let's not even get started on the fact literally 0 mushrooms have been posted. I'm sure all the people with LC issues before they got into agar were just stupid, as you put it, and you're just godly right?

Perhaps he's talking about bags or bottles with both grain and manure/CVG :grin:

Eagerly waiting for cultivation to evolve here. Perhaps it's all a scam from the electricity companies that made us sterilise for longer than 15min.

I think if that ever was found out that mushroom growers everywhere would just start jumping in front of trains. Omg think of the 100s of thousands of hours wasted pressure cooking all the grains, cakes and lc and agar . no worries mate my last 3 pc bag runs were only 2 hours at 15psi instead of 3 or 4 hours those 6qt bags stay super hot for like 6 hours after the run.

Not sure why you are putting manure substrate in a PC to begin with. That should be pasteurized not sterilized.

Pasteurizing horse manure can be a bit tricky, so if you can sterilize it and inoculate it and then let it colonize in a sterile environment you've made it easier to use a good and cheap substrate.

Check out MudaFuka's bottle TEK.

My only issue with cultivating has been getting the pasteurization of horse manure right and since it's free sterilization is quite beneficial.

The microbes one wants when pasteurizing isn't really needed since the substrate is colonized in a sterile environment and no contaminants are there to be fought off.

Lol once again I'm not bullshitting. This definitely happened. And the grow was still successful. In order to correct the dried out manure, I simply added water.

I went from PF manure jars (BRF,gyp,manure) crumbled to bulk sub (plain manure PCed at 45mins (THIS IS WHAT BECAME DRIED OUT, NOTE THAT IT WAS NOT HYDRATED PRIOR TO PC) and put into tin foil baking trays.

I've used this tek 3 times now with great results. Each tray usually has about 4 flushes

That's not the definition we use for mycology. In dairy they do partial sterilization with their pasteurising

In mycology we do 140-160F core temp for 1-2 hours.

Partial sterilization is 170F for 10m in most cases.

Dairy and juice use UHT "pasteurizing" which is 250-275F for a couple seconds or so. That's partial sterilization.

Maybe its just how I think, but I will always consider pasteurization to be under the umbrella as "sterilization." But of course things have different meanings in different fields.

Not really look up pasteurization units (PUs)

Uht is partially sterilized with shelf life approaching a year in dairy

Htst is still just pasteurization giving a shelf life of a couple weeks to a month

There's all different kinds of pasteurization. Only uht is partial sterilization

Sterilization aims to kill everything, pasteurization does not. But the general goal is each is very similar, no? So if I were to refer to these processes in a general sense, please tell me, what word should I use????????

EDIT: Ill just say "heat processing" from now on

Something is not 50% sterilized.  It is either sterilized or it is not. 

You are trolling at this point.

Quit editing your posts after you've been corrected by someone.  You're trying to make yourself look better, and failing.

http://www.revoxsterilization.com/article/sterility-assurance-level-sal-vs-log-reduction-understanding-difference

sanitation is a 99.9-99.99 reduction (3-4 log reduction)

disinfection is a 99.99-99.999 reduction (4-5 log reduction)

sterilization is a 6 log reduction at least 99.9999 once you get to 0 theoretical organisms. so it's not just 6 log reduction it's 6 logs past 0 so you have a SAL of 10-6. six logs past 0 so there's a 1 in a million chance of a survivor. since sterilization has to be expressed as a probability

sanitation and disinfection can be partial sterilization if the CFU load is low to start with.
like cleaning a stainless pipe with caustic, then rinsing with water. the pipe is now surgically clean, free of any soil or debris, then either 170F water is ran through the pipe or a sanitizer is ran through the pipe. neither of which is sterilization may still be considered partial sterilization in this instance for this purpose.

we sterilize grain jars, that's not going to correlate over to anything the beverage industry does.
