[@michael_rodriguez]

I'm actually very happy to see someone use a grain to grain method with the bags. It's hard to find a video that explains grain to grain using spawn bags. Everyone else is doing liquid culture inoculation, but honestly there are so many videos of LC and hardly any of G2G using spawn. Thanks 🙏🏼

Try 1 piece of colonized grain on agar or agar to LC. The combinations are endless.

Nice upgrade. The "sealer" is actually a spacer for the bottom to keep your jars/bags off direct heat. ;) Been canning vegies with one of these for years... love them.

Thank you! You are so right! I started using it the correct way! So much better cause it does not rust!

[@jordanmercier3616]

@@BoomerShroomer you can use a 5 gallon bucket lid to keep the bag from sealing off the vent port, they're almost all polypropylene and can withstand like 500F before melting. It will deform a bit, but it won't rust.

[@BoomerShroomer]

@@jordanmercier3616 you’re going to end up melting the spawn bag. The spawn bag starts to melt around 250F. You want to sterilize the bag around 212F for 2 hours or 15 PSI. More heat will melt it.

@@BoomerShroomer oh no, I'm saying you can use a 5 gallon bucket lid on top of your bags to keep them from sealing the vent port on your PC, the plastic the bucket is made of won't melt in your PC, not to cook grains at 500F. It won't rust that's all.

[@erik_carter_art]

Might have been good to inoculate the three bags with an equal volume of liquid culture. This could remove any slight edge introduced by accidentally giving one of the bags slightly more or slightly less of the pre-colonized grain. Regardless, really fun experiment! :) Testing different ratios and combinations of these and other components would be fun too!

[@juanjoserojas1919]

You're unbelievable, thanks for share, greetings from Colombia !!

[@nachocheese132]

Glad it was helpful! Make sure that if you are using the bigger pressure cooker to sterilize them long enough! If you have more than 4 bags then do at least 3 to 4 hours! That’s really the only thing I had an issue with.

Hi Ashley! First I have to thank you for making everything so simple! I have came a long way since watching your videos. I still watch them daily before I attempt a new method you have shown me. Thanks for your help and making me a pro! I do have to ask where you find your bulk grain? I can't seem to find Milo anywhere locally. Do you have a vendor? Thanks so much!

[@BoomerShroomer]

I get mine from the local feed store called Fenton Feed Mill. Have you tried a farm store?

[@mdoggm13093]

Milo is also called sorghum in case its listed with that name

[@Arthurxxxx]

helped a lot! thanks!

[@BoomerShroomer]

Glad it helped!

[@chrishimes5656]

Hi Ashley, thank you for the great content. How long will a spawn bag last after sterilization (shelf life?) before it needs to be used? ✌️

[@jameswposthumus2490]

Hi Ashley, I've watched a few different videos and I find it interesting that after soaking seeds you transfer them directly into the bags, no drying time needed? Clearly that method is producing success. James

[@martinvasquez2240]

Cool video but I been reading through the comments and you tell someone you leave the grains to dry for 20 min before u put them in the bag and another person you told them you don’t let em dry you put them straight in the bag. Good video but missing the little details that people want to know. And your experiment would be more accurate if you weight it out the spawn before you put them in instead of eyen it

[@henrikgustafsson6581]

Is there alternatives for people with no presssurecooker?

[@christian9506]

One thing to mention is the cost. 50lb bags of milo and millet average around d $50. Whereas the whole oats are $15. It’s also easier to find oats pretty much year round. But I do agree that the smaller size of the milo(sorghum) and millet do allow for more inoculation points and more than likely faster colonization.

[@BoomerShroomer]

The local feed store where I live sells 50 pound bags of milo for about 25 bucks and the whole oat is about 12 bucks per 50 pounds. Maybe you can find it cheaper at a farm store or feed store in your area. I usually do a mix of milo and whole oat. I am making a new spawn bag video to show my go to recipe after using it for 6 months now.

[@christian9506]

Very cool! Thank you soo much!

[@barbarossalynn7271]

[@BoomerShroomer]

I get my unicorn bags from myersmushrooms.com/shop and my grain from the local feed store called Fenton Feed Mill. Yes, you can use jars.

[@mikehancho1613]

I wanted to like whole oats because of the price but ultimately had a lot of stalling with whole oats. Millet is my go to. Also with millet it's easy to see any contamination because millet is really light in color!

Milo is my go to. I just can't stand the smell of millet. lol

Please don’t take that the wrong way just could not ignore that lol.

[@g-lurk]

a couple questions: 1. what kind of sealer do you have? I have a Foodsaver, but have not yet used it. 2. do you make your own spawn bags? I see yours have AE patches? If i were to make my own, could you recommend a specific bag to purchase? 3. when you sterilize, you just fold the top over to close it off, and only open it when G2Ging? Then you seal (without vacuum) after you've inoculated them? Thanks for your videos, they're very helpful! I look forward to your response!

[@tuchavito0303]

Hi Ashley, your video is really helpful, I have a question, did you touch the inside.of the bag when you were pouring?? It seems like so, so I can tell that I'm way to paranoid with contamination when opening and inoculating bags.

[@II_superluminal_II]

I think the more experiments you do the more people can be confident in getting into mycology

[@donnbialik9085]

Hey Ashley, now that you are doing liquid culture, have you considered repeating this experiment? I think the amount of spawn/LD added to each bag should be more precisely dosed to get the most empirical results. Also, the size of the grain create a significant difference between the empty space in the give volume. Seems like milo creates a sweet spot regarding the space the mycelium has to grow verses air exchange. There might be other factors involved, but my hunch is that each species of fungus might slightly prefer different grain sizes (and obviously each grain type or mix of grain/sawdust/wood species also play a factor in rate and vigor of growth). I wonder if rate of growth impacts quality/quantity of fruits. Have you read anything about this?

[@BoomerShroomer]

I am working on a new spawn bag video. Been capturing footage for months now. Should have something out in a few weeks.

[@crazsilversc2884]

Can you use pasteurized manure or not? As a beginner grower I have found some premade bags on Amazon and they have that in them. Is there anything that should stay away from if growing medicinal instead of gourmet?

[@nicocerta3271]

Where do you store a grain bag after inoculating? In dark or light? Do you keep it warm?

[@sindrerudshaug]

I get good prices on whole oat. Can I make a mix of whole oat and something else and use also oat in the tub? Or just go with the Vermiculite, Perlite and Gypsum?

[@samTollefson]

Thank you for your very informative video! I am new to this game so I may not understand how it all works, I don't know why everybody seems interested in the race for the fastest-growing spores. It would seem to me that the final production weight would be the most important factor in growing shrooms or growing anything for that matter so long as there is only a week or 2 difference to maturity. What am I missing?

[@bliitztf72]

So do you not have to let the grain dry for a little bit? Or can you just drain them and put into bag straight away?

[@hi_1833]

Isn't it harder to seal the spawn bag with the sealer when the top is wet after sterilization? Have you faced this issue? And in case the spawn bag were to be inoculated with a spores syringe, wouldn't it be better to pre-seal the bag before sterilizing it? I have head that can cause the bag to bust inside the pressure cooker though, but others do recommend doing so. Any advice?
