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.

[@chitsu1388]

I just want you know the things you put out there, the information you give, the tutorials you show, they save SO many people. You have healed many people, and will heal many more. Mush love

How did the grow go?

[@johnwayne420]

Thanks for the video and knowledge I was just going to upgrade to bags good timing. I hope all is well

[@misfitmaniac3084]

Yooo Philly Geee on a dailyyyy!!

[@gp8699]

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

[@AaronAlso]

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

[@MaggieF59]

Thank you for sharing this. I finally found a video I could easily understand and follow.

[@PhillyGoldenTeacher]

I'm glad it helps! 🙏🍄

[@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

[@pkgmsu]

And this guy is awesome so much helpful information

[@cyberdurden1284]

I just ordered adhesive injection ports with your promo code. Thanks.

[@tmorrissey5112]

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!!! Mush Love from CO.

[@marskat8530]

Have you been using a liner in your tub? He recently made a video about this and it made my grow 10x better

[@tootegozy4998]

Thanks for the clear instructions and a great video. I grow oyster mushrooms and didn't know that I can put my grow bags into the pressure cooker.

Wish you the best on your journey! 🙏🍄

[@JohnSmoke-ih1ow]

Thanks Ohilly

[@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

[@sgtpepper.6511]

Excellent. Thanks..!!

[@failure2leisure847]

Awesome thanks!

[@pamelajohnson5056]

Loving the lessons. Thanks for sharing your knowledge.

[@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!

[@adamxt3hxpwner]

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]

@@PhillyGoldenTeacher hello sensi. Can you help me with my rye ? Can I just soak the rye in cold water for 12 hours and then use it as inoculum? I'm new to mycology and you really helped me out. Thanks

[@markmettles9148]

Love the vid! Was curious what kind of laminar flow hood you use? Tried looking through your products used but didn’t see that at all.

[@doncromwelljr4926]

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

TY! PGT

[@tyo6896]

Clever mod friend 👌 😀

[@toddwmac]

Thanks PGT, great stuff as always. Do you usually use LC in you bags or do you also use agar? Your agar videos got me hooked on working with agar but I've not used bags yet and was wondering if there are any tips. Thanks!

hey PGT, can you make a video on your room set up and stuff

[@christismith659]

Thanks so much for this! How long do these bags keep before you need to innculate?

[@HiTechFX]

Thanks brother, your insight makes the process easier.

[@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.

Hahahaha dude drew is awesome I had no idea u recommended him. See and this is why ur the master my friend

[@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!

[@miladbozorgnia3571]

Great video. Thanks for sharing. I apologize if you’ve already answered this question but how long do you let your millet soak in the bags after adding the water before putting them inside the pressure canner? Thank you very much. Your instruction style is GOLD!!🙏🏼🙏🏼

[@excelself]

He doesn’t soak them per say just adds the water 9:29 after all it’s called “no soak millet”

[@dontwasteammo1271]

Thank you.

[@PhillyGoldenTeacher]

Thank you as well for being a part of this journey! 🙏

[@iminvisible0]

Haha, I did the same thing with nuts and bolts to make a trivet 😄 Depending on the diameter and material of your holy plate, a bolt leg in the middle will prevent it from sagging under weight.

[@markchick8385]

Use Aluminum.Or as I did You'll have a rusty mess.

[@TheElan5]

You always release videos right after I try something for the first time 😂 You’re the man. Can’t wait to take a stab at this no soak no simmer millet tek. Can you do it with bird seed that’s had SF seeds poured off?

[@PhillyGoldenTeacher]

It's possible with birdseed, I personally haven't done no soak no simmer on birdseed with bags, but I have done it with jars. There will be a video coming out about no soak no simmer grains in the near future here.

[@TheElan5]

@@PhillyGoldenTeacher Amazing, thank you for this! I've seen a few teks circulating that I want to try. It just baffles me that whole white millet is more expensive than bird seed. Thanks for all you've done for this community!

how long did you let the millet soak for?

[@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.

[@magesticmushroomgarden6914]

ive always been fine pressure cooking oat jars for 1 hour.

[@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.

[@omg_wtf]

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

[@426superbee4]

can use malt o meal for the medium. for spores

[@Parikchp]

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…

[@etnobotanicaperu]

THANKS FOR SHARING MY FRIEND, the birdseeds hydrated in hot water ? or cold boiled water, For how many hours ? thank you and that you are very well,

[@marcusbostick3246]

can you use Black cow manure for mushroom grow bags

[@shardj5151]

Does the micron filter pressed up against the plastic like that not prevent air flow too much?

[@thesuburbanelectric]

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

[@Akovdan]

PGT we gotta get you a new mic bro

[@davidkalk2451]

PGT, greetings! If a grain bag is faulty after, pressure cooking, can it be rebagged and reprocessed? Rookie mistake, maybe: before sealing I opened the top and fluffed the oats from the outside. Then I doubled sealed it with my food saver. Did I infect it enough to need to reprocess or pitch? On top of that I pressure’d 3lb. Bags for only 90 minutes. Opinions and suggestions?

[@greatwhitecoyote]

If you're using millet, does it change the prep work for grain bags ?

[@Hooger7]

Do you need to moisturize the millet like the oats?

[@dobb1984]

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

[@abgoldate]

I wonder if you could use the same 1:2 water/grain tek in jars also.

[@longfeatherlong8228]

I do.

[@shaunm1983]

I feel like going to bags just for the easy break and shake

[@Thebigbendfungicompany]

Nice modification on the PC plate

[@RenaissanceSteve]

Is bird seed better to simmer or no simmer for bags?

[@feelsoezy]

Hey PGT I am following your broke Boi guide but I'm just looking for the next step placing them into containers after jars. Did it get removed? Where can I find it?

[@patches1107]

Will an Instapot work to sterilize? it doesnt quite get up to te same PSI but maybe extending cook time will help?

[@luisrobles386]

Does millet no soak no prep tek effectively kill all endospores ?

[@Shroomvizion]

What do you recommend jars or bags? I’m trying out making bags myself. 50/50 success with purchasing pre sterile bags. I like jars a little more.

[@TheOffCycle]

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

[@oneguyfungi]

So hey PGT is there no need to soak millet ?

[@michaelholbert5042]

If you have millet mixed with bird seas, do have a different water to millet ratio than shown in this video?

[@raysosa3531]

I have a quick question for you. I have a Crockpot pressure cooker. The manual says it goes up to 10psi. I know to sterilize popcorn for mushrooms it has to be 15psi. If I were to simply leave them in longer than 3hrs would that suffice?

[@dmjreptiles]

Hey, where do you get millet?

[@user-bb7sr7kr9z]

Does this also work with popcorn?

[@maribellelebre6809]

Have you tried quinoa?

[@Beinhartwie1chopper]

Can I use hulled rye or is it going to be too mushy without the hull ? All the rye that I can find is already hulled.

[@modeob88]

Millet works to colonize magic mushrooms ? What do you think is the best best best food for colonize ? i had tryed rice, but have problems with the exact cooked point :(
