How to Make Sterilized Grain Bags for Mushroom Growing

[@brennonmorning9682]

Thanks for sharing your knowledge. I want to add a manufacturer's recommendation from Unicorn Grow Bags. Unicorn states that you should not "Gusset Fold" your bags and instead "Flat Fold" them. The way you folded the top of the bag before sterilization by folding in the gussets in before folding the bag down is considered the gusset fold. Instead you should flatten the opening of the bag with no folds and then fold it down and under the bag.

[@PhillyGoldenTeacher]

I can't believe I missed his videos on flat folding. I'm very happy you pointed that out. I will definitely be flat folding going forward with my bags.

[@patricknevermind8529]

Bro, thank you.

[@TearringNable]

Curious, why would it make a difference between folds? Would it make sealing easier or is this for added grow room?

[@kdock13]

@@TearringNable The gusset fold means that your impulse sealer needs seal through 4 layers of plastic, making 2 seals, instead of 1 layer. This increases the risk of blowouts/leaks. You should also adjust your sealer so that you get a good tight seal in one pulse without burning the bag. Doing a second seal in a different spot is definitely a good idea.

[@80polishprincess]

@@PhillyGoldenTeacher can you tell me where you got your hood? This is a piece I'm thinking of either buying or making. Do you favor the bags over jars?

[@pottervi]

I started my journey into mycology about 15 years ago before youtube was really a thing. I had to read for hundreds of hours on the shroomery, and watch the couple vids RR had. Your videos are ultra clear and to the point. Simple teks explained very well without any bs that you don't need. I wish your videos were around back then

[@holothurie]

Same here. Thank you Sir PGT

[@adamxt3hxpwner]

But still john, thanks for all your research over the years. the last 15 years myco has come a long way.

[@pottervi]

@@adamxt3hxpwner oh fer sure. I hardly got into agar because you couldn't get supplies as easily back in the day. To start I had to go buy agar strips from an Asian market and grind it up with my coffee grinder lol. But now with Amazon and youtube it's cheap and easy. I'm excited to try the 2oz condiment cup thing. Also making a flow hood looks a lot easier now. Its amazing

[@LarsLarsen77]

And you usually got the worst advice ever on shroomery. I actually had to figure everything out by trial and error myself because the "tek" was always a failure.

[@pottervi]

@@LarsLarsen77 it wasn't too bad. Was able to grow more than I needed so everyone benefited.

How big of pot do you use ?

[@ericcartman7102]

Thanks for putting this up! As of this week I was curious about stepping it up with bags, so funny you upload right after my curiosities. The universe is running on all cylinders today

[@dustinbrady8900]

You have a very kind soothing voice.

[@Vorpal_Wit]

Hey Sensei. Can you cover prepping the bags for fruiting - like where/how to cut the bag for the first and any subsequent flushes, things to watch for/avoid, etc? Thanks.

[@ScottWConvid19]

This isn't substrate. This is grain spawn. You don't fruit grain spawn unless it's a cordyceps fungi. You add the fully colonized grain spawn to substrate

[@TheNativeNation]

Word bro. Glad to see ya back in class!

[@gp8699]

Thanks for mentioning why you leave the filter patch on the outside when you fold the bag to put in the pressure cooker!

[@ronnienoneyabusiness2844]

I had problems with bags but i wasn't pcing them long enough...thanks for the info pgt

[@thomashugh7086]

Thank you for posting a new video I'm so stoked to start trying my hand at gourmet growing. That and reishi and cordracepts eventually

[@theresasteinbacher]

I love your video. I noticed you didn't wash or cook the millet like you did for the brown rice. Is this because Millet is a small grain? TY. Theresa

[@OrgoneDevices47]

If you dont have a Impulse Sealer for the end sealing, a vacuum sealer works if u press down a lil bit n do it like twice...

[@longfeatherlong8228]

Also aluminum foil on both sides and an iron.

[@SquashDaBeef]

@@longfeatherlong8228 the wife's hair straighters with some paper towel also works great :)

[@peppergrowmienola4850]

This was awesome info. As a mycologist I am looking to widen my skills with agar and grain bags. This video has me confident I can make sterile bags of grain no problem. 👍

[@PhillyGoldenTeacher]

Wish you the best on your journey! 🙏🍄

[@AaronAlso]

Safety tip: You can use a butter knife to lift the vent for 10 - 15 sec to encourage sealing.

[@michaelhudson3445]

i really like the mesh gate panel over the saw horses i'm gonna have to do that excellent!

[@MiguelRodriguez-wn8mc]

good explanation of what material could be used as an air filter for the grow bags, if you want to make them yourself

[@Readlong247]

Thank you for suggesting adding coffee grounds to the bag to soak of moisture. I didn't have any but I did toss about quarter cup of brf into each of my two pounds bags

[@UMepher]

I've seen some people add a little vermiculite as a sort of moisture buffer. It'll help keep any excess water from pooling but will release it to the grain if it's too dry, I guess.

[@LarsLarsen77]

It's not just the larger volume of grains that takes more time. The plastic bags are more insulating than glass is, that is they have a lower thermal conductivity. Even massive mayonnaise jars cook faster than even small bags.

[@shellieb1792]

I am loving your videos! I am a newbie to trying to grow mushrooms. You are making it easy for me to get the growing experience that is needed to be successful. Thanks so much.

PGT! it's nice to see you back. I hope everything is going good for you. I'm just suggesting a video about all your supplies that you purchase. I have bought most of the stuff you have used and shown us, and it could help a new mycologist a lot. Everything I bought works great. Thanks for everything, man.

[@PhillyGoldenTeacher]

I'll add that to my list of video ideas. Thank you for the suggestion.

[@avadakedavra6695]

You taught me everything I know man!!! I’m doing an uncle Ben two right now then doing some mono tubs. Thanks for the new vids I was hoping to see some new stuff. One thing I’ll say is following everything to a T I still have trouble getting lots of pins. Only One dubtub I’ve ever had pinned a lot. I have “gotten it down” in my head they just won’t pin across like all the videos do, even though most show the best results possible and don’t show the problem grows I feel like I get less than normal results… TIA!!!

[@misfitmaniac3084]

Yooo Philly Geee on a dailyyyy!!

[@doncromwelljr4926]

Should i add gypsum to my grains while they soak? By the way. Your videos are an absolute godsend...

[@UMepher]

I think these days gypsum is considered pointless and bro science. Some folks have been using it for decades, so you definitely can use it, but plenty of people will tell you that it does nothing to justify adding another step or ingredient. Same with soaking and or simmering grains to hydrate before sterilizing. That used to be considered an essential step, but I'm just getting back into the hobby after an extended absence and it seems that a lot of knowledgeable folks have great success now without bothering with any of this.

[@cyberdurden1284]

[@rPackyyy]

What length of stainless-steel screws did you use to elevate your trivet?

[@Muay_Thai_Mycology]

Thanks for the videos mate! I’m finally getting back into cultivating after years of foraging 👌

[@EvolvedCognition]

So I'm inclined, due to ease of access & your video supporting that brown rice is the best grain for spawning, to use brown rice. In this vid there's an opportunity to elaborate on what the language "Now here I have some oats [or interchangeable grain?] & bird seeds that I've soaked overnight with some hot water." This suggests the water was kept hot for a 7-8 hour period; how was this accomplished, assuming that language is accurate? There's a fan in the frame, was that used, post soak, to decrease overall moisture levels? If so, for how long? Inquiring minds need to now the minutia without a need to guess. :) Thank you!

[@TheShift_OfEnergy]

can I use a big steel boiling pot and a plate to keep bags above water? just beginning

[@marcusbostick3246]

can you use Black cow manure for mushroom grow bags

Can brown rice be used? If so what’s the process? It will be for pink oyster liquid culture inoculation

[@KillerKlown707]

How are you only using 3 quarts of water for a 2.5 hour long pressure cook? I have the same pressure cooker the presto 23 and I need to use just over 4 quarts and I got it rocking right at 15 psi the entire time

[@kloii]

I'm really struggling with sealing my bags. They come out of the PC with beads of water between the layers of plastic. These beads make the impulse sealer not work properly.

[@bqoutdoors2334]

If I put one two pound bag into shoe box’s how many shoe box’s would I need for one 12 or 6 shoebox. Thanks

[@mattt9634]

Few questions can you use 90% iso, and how long does the gran bags last before needing to be inoculated?

[@HelpMe_OrNot]

Use 70% iso as 90% will evaporate before killing much bacteria. For grain jars, it is best to inoculate as soon as they have cooled down (1-3 days storage max). I assume the bags would be similar. A veteran would know much more than me, but I stick with making the jars/bags I'm going to use that day to help prevent contam. I hope this helps! Mush love and best of luck on your journey!

[@mattt9634]

@@HelpMe_OrNot thanks a million bro!

[@UMepher]

It seems counterintuitive, but 70% is proven to sanitize better than 91% because the water content allows it to sit longer on the cells of the nasties you are trying to kill. I've never seen any data pertaining to how great the difference is though. And the sooner you noc the better, but if you've cooked your bags long enough with a proper hydration level, a few days shouldn't make much difference.

[@dch7774]

Where do you get the bags

[@junerobinson1220]

When we are saying overnight .. what does it really mean ? Overnight doesn’t have to be 24hrs so how long ideally we allow grain to soak in bags?

[@thesuburbanelectric]

Why do you run Millet without pre-hydrating, but not the Oats?

[@waynegreenway5445]

Great video Sensei. How long after processing in the pressure cooker are the bags considered clean and viable? How long can the be stored for at room temp or refrigerated? Thanks!

Hi PGT great video. A quick question, I don’t have a flow hood, would it be advisable to seal the bags before the sterilisation process? The filter should help exchange of air anyways…

[@UMepher]

Some people say go ahead and seal them, some say they will burst, with .2 micron filter patches being more likely to cause bursting in the PC than .5 micron. Others seal and wrap them up in various things to discourage expansion. Another option is to fold the tops over twice and secure with 2-3 binder clips, which may allow pressure release, if necessary, but will keep the bags closed well enough otherwise. You can then seal the bags without first removing the clips or unfolding, or simply leave the clips in place and skip sealing.

Does it have to be millet or can i do rye?

[@byzantium100]

Question: what happens if you get as much air out of the bag, seal and pressure sterilise them. Will they explode? I came across a video where he seals then pressure cook them.

[@Yewgeni-sj8uy]

If you get enough of the air out I don’t think it would explode but I think that it could still damage the micropore patch. Just seal the bags after pressure cooking they will have a vacuum seal after PC ing anyways

[@4.23.21]

Should I wrap the bags on aluminum foil?

So hey PGT is there no need to soak millet ?

[@badmachine7862]

Thanks for all the good advice. Do you have a recipe for sawdust spawn bags using hardwood fuel pellets. There are several that have varying amounts of water, some with gypsum some not etc. Want use it to inoculate outdoor beds and reckon the critters would eat grain spawn.

[@LarsLarsen77]

You can't put stainless steel in a pressure cooker, it will cause galvanic corrosion of the aluminum of the pressure cooker. You can, but not if it's touching any of the aluminum which it would have to be to hold the base up like that.

[@Slothen]

one thing i don''t get, is why not just impulse seal it before doing the sterilisation in the PC? the air should escape through the GE port anyway, right?

[@Yewgeni-sj8uy]

Not fast enough tho. The bag would blow up or the GE port would get damaged

[@MacCelium]

Thanks for all you do.

[@dobb1984]

If you're doing a grain to grain transfer, can you do that before you seal these up?

So if iv got a cloned sample in an ergot cup can i just buy uncle bens and cut open the bag and put it into another air tight bag with the ergot and just use that ?
