[@mtsafer]

I almost exclusively do liquid culture to sterilized master's mix bulk. I use a silicone sealant as a SHIP, and I put about a half inch of boiled popcorn at the top of my bag. I inject from above onto the popcorn. I found that I had mixed results injecting directly onto bulk, but including a grain layer to start the culture on has made it 100% success rate.

[@Mossycreekmushroomsofficial]

Yeh, it's the grain pocket I'm trying to get away from. It adds another step to the production process. Also, I wouldn't consider that LC straight to bulk. You are still using grain as the intermediate step. Though it's one part in the lab.

[@jeremylastname873]

I learned a long time ago that pasteurized substrate behaves very differently from sterilized substrate. So, it’s been a year. How’s this progressing?

[@spidertickles9710]

I've done this semi consistently. Top inoculation helps and the more LC you use the better but adjusting the moisture level of the substrate to accommodate the extra from the LC is something I'm still working on. Just a disclaimer, I am a hobby grower so take what I say with a grain of salt🤷‍♂️🍄❤

[@Mossycreekmushroomsofficial]

It makes sense to me. You've been doing this with Master's Mix?

[@TheKellisunshyne]

Well you sound pretty educated on the matter for a hobby grower.

[@mansrevenge]

Even if you used an entire syringe, 10ml of fluid wouldn't make a big difference, right? At 5lb blocks or larger the effects should be minimal

[@MissBlackMetal]

​​@@mansrevenge well, Andrew said that he uses 10cc of LC per bag of bulk substrate, but OP said that "the more LC you use, the better the results"; so assumedly, you could be adding quite a lot of extra moisture to the substrate. So, assumedly, you'd have to predetermine roughly how much LC you'll be adding to the substrate, and then factor that in to the preparation of the substrate so it's not too moist when you do go to add the LC in. Just a fresh newbie here, but that's the understanding I'm getting from OP's comment.

[@mansrevenge]

@@MissBlackMetal It's a good assumption, but the quantity is negligible. 10cc of liquid + or - should have no effect on substrate consistency. Especially when doing bulk.

This is part of our sinister plan to get away from disposable plastic bags. Shaking is one of the biggest problems for hard containers, so we've been trying to find good ways to get away from it. Also need a good solution for the container itself. If anyone has any solutions that don't suck too bad, please let us know. Would be awesome to say goodbye to disposable bags.

Benjamin erickson: I use garbanzo beans aka chickpeas. They shake up so, so so so, easy and rebound so fast that in less the two hours I see growth again. Never beat a glass jar again, use garbanzo beans my friend. 🍄❤️

[@davidafenderson3446]

Based on the McKenna jars tek only I use 1 gallon anchor hocking jars instead of mason jars. Check out McKenna jar tek. Ok, my tek is based on the McKennna tek but I put 1/4 grain and 3/4 bulk subs in glass jars (wide mouth anchor hocking) and inoculate with spore solution. Now I’m going to use LC and fill the bottom 1/4 with straw. Much cheaper and no more plastic bags. ❤️🍄

[@jrcicirello]

The sinister bags can be substituted with biodegradable bags. The main drawback is the cost is not really commercially friendly. The cost is quite expensive compared to the regular bags used. However, the foot print of the bags verse any other farming on a commercial level is quite large compared to mushroom farming.

[@Mossycreekmushroomsofficial]

@@jrcicirello Also, there are currently no biodegradable bags for mushrooms on the market yet. All listed as such as actually oxo degradable. Which is actually worse IMO.

Hi andrew i wrote you about it as a comment to your "Making a Grain Spawn Master using liquid culture and agar." video. i usually put dry rye into my substrate with 5-10% (dry weight) then pour the water in ,seal and put a frogtape at the future injektion spot. then pressure cook. my bags do hold the pressure and do not tear. after cool down i put the bags into my flow hood, lift the frogtape half way, inject LC in that steril plastic spot, and cover again with the frogtape, wich is still sterile at the sticky side. no need for alcohol. no need for for grain spawn. i do shake my bags afterwards and they colonize in around 12-20 days. works for me 100% . keep up the good work, bro!

[@Mossycreekmushroomsofficial]

The only issue I have with the grain pocket approach is that it is an extra step in block production. It might help save you from needing a HEPA filter, but it's more labor.

[@brucekidd6133]

Hey! Glad to see someone else making this work! I do liquid culture to bulk with 80/20 sawdust and wheat bran mix (with a little added gypsum). I've made it work for Oysters and Lion's Mane so far but it's many weeks slower than grain spawn.

I partially think the heating process from the pellet mill degrades the lignin to a degree and allows the mushroom to colonize easier, since they have to break down the lignin anyways. I wonder if this would work with non-pelletized straw. One person who got this to work is the infamous Agar on Shroomery who was able to colonize his "Myco Nitro" mushroom compost straight with LC.

Hi there. Thank you for good and usable content. I have had great success on Cannabis waste. It is legal to grow here in South Africa, so I started trying to compost and use the waste in a waste none production system. I take the wet (fresh) bio waste, pasteurise it, ad it to some pasteurised kraal manure and course compost mix (I pasteurise the ingredients separately, for no other reason than logistics). I then inoculate with liquid culture (a distilled water and 4% honey mixture). Within 4 days I see mycelium growth on the Cannabis. Note: I always mix the parts well, then add a layer of cannabis bio waste wich have been dried thoroughly on the top then drizzle the LC over from the top. Under ideal circumstances I have had a personal best of 20 days from inoculation to pinning. Though the norm is 30 days. This is done in a Southern hemisphere coastal area with a relatively stable environmental humidity of 75% and temperatures ranging between 25 and 27 Celsius.

Inovation award of the day goes to you man good man. Ta-Da! I’m mixing a new batch of LC from my oysters and wine caps right now just to try out in a week or two. Maybe I will try a McKenna jar approach but I’m going to use 1 gallon anchor hocking jars instead of mason jars. Pack them with straw heavy bulk substrate and inoculate with LC. I hate using plastic bags so if you haven’t heard of this here is a quick run down on the tek: Glass jars, 1/2 full of grain. Once colonized and consolidated you pop the lid on front of a flow or inside a SAB and fill the jar almost full with substrate. Allow it to consolidate again, then casing layer, and finally fruiting conditions. Ok, my tek is 1/4 grain and 3/4 bulk subs in glass jars (wide mouth anchor hocking) and inoculate with spore solution. I have had great success and it could rid the industry of plastic bags once and for all. 🍄❤️

[@Mossycreekmushroomsofficial]

Yeh, I don't really like the glass jars when I tried them as fruiting containers. Too much to get the myc out.

Thanks Andrew! I inoculated (5) 10-lb master's mix blocks with Ganoderma Sessile and all of them fruited successfully. Yield was slightly lower than what I would have if I would use grain spawn to inoculate. Although I think it is very practical to use this method for the kind of species that we don't grow very often like reishi, turkey tail, etc. Just to eliminate labor and time on preparing grain spawn.

[@padoco73]

I've been having some limited success with going directly from LQC to substrate. Granted, most of this is due to my being new and just not knowing any better, but this is what I did... First, I put a dollop of high temp silicone on the side of the bag, effectively creating a makeshift self healing port. This is where I made the injection. Second, I've only done this with Shiitake into a substrate comprised mostly of oak pellets, and with King Oyster into a mix of soft maple shavings, oak, & wheat bran. In both cases, these were in an Instant Pot for 3 hours for pasteurization...which may give you an idea of the size of the bags (they're smaller). Third, the growth has been rather slow. In the case of the Shiitake, it's been almost 2 weeks, but there is definitely mycelium growing. The KO showed growth after about a week and is definitely going faster. Fourth, and this is really showing that I didn't know what I was doing...I used 100 CCs of culture, not 10.

[@Mossycreekmushroomsofficial]

I have done this by using a handful of oat grain thrown in the bag with the bulk sub. place it in a way that it sits on the side of the bag somewhat buried. inject through the bag is you did and hit the grain "pocket", mycelium jumps from grain to sub with full colonization in 4 to 5 weeks.

I've grown Hericium on Hardwood sawdust and wheat bran, pre-sealed my bags and PCed, inoculated via LC syringe through plastic and cover with micro-pore tape (Might switch to a non-breathing tape because the filter patch doesn't need help in my opinion). I normally inject a few different spots to try and speed up colonization. My first run I did all of my work in a still air box, but second run I did it in open air (In my messy bedroom of all places) just being sure to heat sterilize my needles and clean my injection spots with alcohol and I've had no contamination issues.

[@jefflambert7513]

You've had pretty good results with this? Is colonization time a lot slower compared to gain spawn? Although I guess consider the time it takes to spawn the grain and then go to substrate may not be much different.

[@cullsans]

@@jefflambert7513 I have since built a laminar flow box and have been using the traditional grain spawn method and I do have more robust grows when using Grain Spawn but my first several flushes of Lion's Mane were using the technique listed above. You can increase colonization time by using more LC if you have some to spare, but the colonization speeds are definitely slower than grain spawn.

[@richardhubbard8695]

I've had success with LC to bulk using sterilized and supplemented straw in PP5 quart containers. I havent tried bags for this, it's just too messy to work with the straw in large quantities. Colonization times were similar to grain inoculated in the same fashion with LC. The substrate was finely chopped straw and whole wheat flower.

It might be a cheaper route for new people to try just buying a 50 gallon drum with a lid, building a stand, and then burning wood or sawdust or even burning oil or ethanol or propane to heat the water.

Just to clarify, this is only rice straw pasteurised, when you said it did not work for sterilization method...... Is that the learning .... I mean that this will work only with rice straw and only if it is not staralized. I draw a lot of inspiration from you, and if it is according to His will I too will start a mushroom farm soon. Thanks again

This is wheat straw.

I am so going to try this. Thanks Andrew!

[@Mossycreekmushroomsofficial]

Do it. You are welcome.

[@jedoran]

I'd be interested in whether you could just swap a percentage of hay pellets into a master's mix to give the LC a foothold. If so, that would lower the cost of the inputs significantly.

[@spencerstephens7594]

Are you just trying to avoid shaking and spawn to bulk proccess? If so you could try doing a small layer of your spawn in your bulk bags and innoculating that after sterilization..

[@Gabi-he6rw]

I made few little bags with sawdust mixed with grounded wheat and corn(about 1-2mm pieces), sterilized in the pc and inoculated with lions mane LC. They are already fruiting. I am also in testing for a one step LC inoculation on pasteurized substrate for lions mane. I dont know though what is a reliable recipe, to have fast growth but also not too much nutrients in order to contam. I will also try the bubbling lc tek but I dont have the materials yet and I still have to experiment with what i have. Thanks!

[@sarawaasdorp1569]

THE GOAT mix. oh man, that is great!

[@shadetreephilosopher5568]

I've tried this a couple times. I put a layer of cooked oats over the top of hydrated masters mix, put a spot of rtv silicone pressed down with packing tape on top of the bag. Pressure cooked for 2.5 hours. Used a syringe through the silicone to spray 10ml of lc on top of the grain. Broke it up and shook it after 14 days. Fruited it after another 14. I tried this because I don't have a flow hood and thought I would eliminate possible contamination this way. This yielded around 16 oz first flush on 5lb blocks (I was average about 25oz using conventional methods). There were lots of aborts. And both blocks I tried got contaminated with trichoderma before second flush came in.

[@Mossycreekmushroomsofficial]

Very nice. I've definitely seen it with the grain pocket.

[@tims.440]

Shade, why do u think you got lower yield and more contamination? Have u found any way to fix those issues? Thanks

[@shadetreephilosopher5568]

@@tims.440 I think the lower yields may have been because the mycelium moved on into the bulk substrate before it had gotten as much nutrients out of the grain as it normally does. Not sure why the contamination kept popping up though. It's been awhile since I've tried this so I'll probably take another crack at it soon.

[@tims.440]

@@shadetreephilosopher5568 ah. Maybe you could put the grain on the bottom rather than top, and inject thru bag to bottom grains.

[@on.belief]

Thanks for the great videos!!! We just had a bag of grain that had green mold growing at the top. Why does that happen? Or more importantly how do we prevent it from happening in the future?!

[@pablo6305]

I have problem with straw. It does take off but it so easy to contaminate and dry up in my bulk sub.

[@marcelatalmazan4271]

I actually recently bought a big bag of some oat grains from a feed supply store and didn't realize they didnt have the husk removed and I was disappointed till few days later when I realized i can probably inoculate them just like that and fruit them right away since they have all the extra nutrients from the husk.I am trying lions mane right now.We shall see how it goes.

[@Mossycreekmushroomsofficial]

Yep, I buy mine as Whole Oats. Still have the hull.

[@achozenshaman]

From 1:40-2:40 he talks about straw, but he keeps mixing up his words so I’m confused. He talks about sawdust pellets, grain and straw and it’s unclear what he means because he switches his words. Maybe he misspoke? “It is literally the straw.” 2:09 “And we ran out of sawdust pellets.”2:19 “And he through some on top.” 2:24 (meaning straw?) “And when I came in and inoculated them, I sprayed the liquid culture over the grains and the pellets that were there....the straw took off way faster than the grain.” 2:26 Can you please clarify? Thank you for the great info!!

[@jrcicirello]

Andrew, you could go direct with pouring directly on too if your substrate before closing your bag then also inoculate by injection towards the bottom as well. I have been doing this with Master’s Mix for some time now. Not sure why you are getting contamination on top of your atmospheric steam processed bags unless you are not running your sterilization cycle long enough. Maybe use sterilization indicator strips in a few bags towards the top of each run like we do. Just ideas being thrown out there for you. We use an Eric Myers style DIY sanitary stainless steel drum atmospheric steam sterilization style system. Not sure if you are still using your trough style steamer. Now for the clincher. We can pre-sterilize our grow blocks for use later and still have nice clean no contamination blocks 6 weeks later. This has proven a great asset during these extremely cold nights (-18) due to our steamer being outside and running our water source off the outside faucet. Your trials with the GOAT mix is fantastic and have talked to Seth as well as placed an order to run trials here as well. Yes, I will share our results with you and the community as well. Keep the stir bars spinning and making that LC, Joe & Darlene at NWA Urban Mushrooms

[@Mossycreekmushroomsofficial]

Hey Joe, I absolutely could do this. That said, I'm getting contamination on top as a failure of the filter patch. It isn't on all bags, just two of them. Pouring on top would work better I think. Please do share your results! Keep Spawning Culture!

[@jrcicirello]

@@Mossycreekmushroomsofficial same issue with filter patches. 11 out of 100 have contaminated in the last 2 weeks. Have a call into Unicorn. Not sure if there was a problem with that set of 100 or what. Have not had that issue before. Will let you guys know about pouring direct since I just inoculated 20 bags yesterday.

[@bigmomma9371]

I'm actually about to try this. I was thinking the same thing

[@cognitivedissident9825]

Just hydrated pea straw, pine shavings, and a hardwood block designed to be burnt for bbq (zero additives). Mixed together at field capacity, bagged and in the PC right now. Tomorrow I'm gonna inject gold oyster LC.. Will this work? Oyster genetics are very aggressive in my limited experience and should go bananas.. I hope

[@robbiebenavidez2788]

I had 3 all in 1 grow bags spawn + grain and 1 contaminated but other 2 it seemed like they had rapped growth on the sub and the spawn but I will try just sub in a week let you no how it goes

[@tims.440]

Update? Howd it go?

[@alexc1105]

I've recently innoculated a load of shoeboxes of cococoir and vermiculite with like a jar of liquid culture... tried to mix it really dry so it wouldn't be too moist when I added the LC but seemed to have gotten it damn close to field capacity. I's been a little slow but so far so good.

[@Mossycreekmushroomsofficial]

Wet Sub = SLow Growing

[@alexc1105]

Yeah. I tried mixing the substrate up with a litre less than the recipe suggested for a 650g block... but as I said, seemed to be very close to field capacity before I added the LC. Wasn't like a smoothie or anything.... just a touch too moist

[@alexc1105]

So it colonized ok... eventually.... but it basically didn't fruit.... there was no nutrition in there at all.... schoolboy error!

[@recless8667]

Have you considered putting in a dab of RTV onto the side of the bag to create a self-healing injector port? Tape isn't sterile, it would make sense to put a series of RTV dots on the bottom of the bag, layer straw on the bottom of the bag, followed by a layer of grain, then the substrate in the packing phase, then inject into the straw layer through the RTV ports with say 2cc of LC each to spread out the inoculation over a larger surface area.

[@longride1993]

Has anyone heard of or tried using sugarcane bagasse as a bulk substrate? I've reviewed multiple experiments resulting in higher yields using it but, I don't see anyone using it or selling it?

[@themyceliumnetwork]

I tried sterilized goat mix knocked up with 10ml LC with no luck yet. wondering if I just need to add a bit more water to the straw than to the HWFP....

[@ToothlessInKentucky]

Thanks for sharing your research.

[@cryptobotboi4459]

Any follow up on this?

[@jidun9478]

You know I have been thinking on something else.... Has anyone done any studies on feeding the blocks after the first flush. I am new and been following you fro awhile but I can't help but think that the mycelium is using grain and the soy husks etc as the primary food source and the substrate bulk more as a house to live in.. it seems to me maybe we could bump up production by injecting sterilized malt extract into the block after the first flush and maybe more... What do you think or has any one tried this that you know of?

[@dougsrefinishing]

I'm not quite sure if this is along the lines you are going for.. I have had success with preparing and pasteurized coco coir/ vermiculite, to field capacity and mixing it 50/50 with prepared/simmered WBS. Jarring them like a BFR cake and pressure cooking for 90 minutes at 15 psi. After inoculation it thrived and colonized quickly. Once birthed there was no need for further substrate and produced some monsters. This might be a small scale of your attempts.. say it was done to the scale of using bags🤔. Just throwing this out there! Love your videos and shared knowledge!!✌

[@Mossycreekmushroomsofficial]

Great video, as are all of your videos. I find them very informative and I have learned a great deal about mushroom farming-especially how much work is involved. I am planning on growing some for our family so I watch and read on mushroom farming as much as possible - and I like how you are very precise in your operations I have a question for you. I noticed that some of your fruiting blocks have air in them and others don't. Is the goal to get as much air out of the bags or is some air necessary?

[@Mossycreekmushroomsofficial]

Thank you, and yes I try to squeeze as much air out as possible while the bags are fruiting.
