Gary, I really appreciate the QC / Test portion of this video - I need a lot more of this sort of thing for our process. We're learning the hard way as we go and your videos are super helpful - thank you! Where are you getting your QC plates and other lab supplies if you don't mind sharing? Thanks again! George in Idaho
Neo Geo Thanks for watching we appreciate you’re support! We get our QC plates through Hardy Diagnostics and our lab supplies we source all over depending on our needs : ) Hardy Diagnostics and Thermoscientific are good brands
Really informative video I learned some key things that I will be doing from now on with my LC it's very easy to pick up what you are explaining I like how detailed your videos are. Will be hanging out watching for the next one after I subscribe. Thanks Gary
I work with almost the same setup, but I insert an sterilized automatic syringue in the big jar through a silicon tube and a needle. The grain jars have an injection port, so I can inoculate hundreds of jars in minutes without opening them, saving time and possible contamination. Also, I seal the bags before sterilization, and do the same as before through an injection port.
@@FreshfromtheFarmFungi Also, I'm working with that setup to inoculate logs in the forest in a most sterile and fast way than the traditional, with only a battery drill and a peen hammer. With the help of two friends, one drills narrow but deep holes in the log or tree, another insert the syringue and inoculats it, and the third one only needs to close the hole with the peen hammer, like when you make a rivet. This way, there is no need to drill big holes and fill them with spawn, or using wax or stoppers to seal it. But I'm still not sure about it's viability.

Greetings Gary, your videos & the information you provide are some of the very best. Thank you for your commitment to excellence and your willingness to share some of your hard-won wisdom with the rest of us! I wanted to ask you about your blood agar and the hektoen enteric agar plates you utilized in this video. Do you make your own, or do you purchase those plates pre-made from a supplier? I would sure love to see you do a comprehensive video on quality control strategies... thanks in advance for your response, Merry Christmas to all of you out there in Colorado.
This reminds me of my work in the OR. Wouldnt hurt to wipe the tube tip before placing the syringe with alcohol wipe to avoid any contaminates on the tip of the tube.
I'm amazed by the informative and quality content that you produce. I'm an aspiring hobby mycologist but I have plans of perhaps one day making it official. I've absolutely fallen in love with mycology. I'm starting from practically nothing but I have full intentions of one day having my own mycological business and lab. :) Mush love
I use my own maple syrup that I make and water. The way I figure It, it comes from a hardwood maple tree. Tress are what mushrooms love. So it contain s the same carbohydrates it’s used to.
Hi Gary! Thanks for another awesome video, thanks for sharing! I couldn't help but notice the cracks in the walls of your lovely laminar flow hood. Is there an interesting story behind that, perhaps one that involves a pressurized vessel unexpectedly coming apart?
Great video Gary! Curious how you got all those cracks in the acrylic windows of your flow hood though. I just bought an AirScience Flow like yours and I’d like to avoid that happening!!😮 Keep up the good work man!
It happened from setting bulk substrate bags against the sides it caused it to heat up and cool down which made the cracks. I replaced them fairly cheap (100$ from the hardware store) but now I only use this hood for culture work and have a horizontal ffu type unit for my bulk substrate inoculations. I love the air science hood it was just a user error on my part haha
I finally had success with inoculation of Morchella around my new house. I found one variable that allowed almost 100% success. All the other spots I tried did not fruit. There’s something that everyone sees every time they hunt Morels but they never take note of it. That’s my secret. 3 years straight with success. It’s not really how you make your spore slurry or grow your mycelium but rather, it’s where you put it that matters!
@@FreshfromtheFarmFungi October. no spawn. Just spores from nothing special except dried morels from spring. Distilled water reconstituted and then 48 hrs with molasses. Then straight into some slippery elm leaf mulch. Then placed in *specific areas* No offense to your scientific method but nature doesn’t allow for complete isolation from mirobrobes and does just fine. I’m just a simple man with a simple plan :)
I use a three way valve in some ozone therapy. It's probably not the best solution, but it would be straightforward to have a line in to the valve, and the other two spots connected to the syringe and the needle, in a linear fashion.
Hey Gary I know this is an old video, super appreciate your video been following along for years. My question would be do you have any advice for using these media extraction lids in a SAB environment? Especially as far as keeping the luer lock sterile
Don't have to speak directly into mic, 20 something in, almost blew my speakers lol. Thanks so much for the help, though. Can't wait to get some started myself.
Thanks for watching! We sterilize everything at 15PSI/250F for 20 min (liquid) 60 min (tools) 90 min (substrates) depending on batch sizes and the sterilization pouches or strips are great for confirming sterilization

I’ve spread many mushrooms while dropping spores placed them A blender with molasses water mix and store them in jugs shaken every day and spread around my yard . Mushrooms galore . I’ve done this with amanita s as well
@@FreshfromtheFarmFungi that’s a good idea. I think the reason molasses works well for me is the fact that mushrooms love sulfur and some sugars . Now I’m going to try your method. I’ve never tried honey but it makes sense honey is anti bacterial . I wonder if when I hydrate the honey more, will it lessen the anti bacterial strength. My bees take a long time getting the honey to the exact hydration so it won’t mold . This is very interesting maybe I’ll add a touch of organic sulfur.
Hey Gary 👋 I gotta get me a media extractor!! Thing is awesome man😎 Does the hose unclip from the jar lid to use on multiple LC Jars or do you have to move the lid and all to another LC container. Cleaning it out in between of course 😉
Hey thanks for watching! They are all one piece so I use a normal lid for storage and have the extractor lids on hand in a sterilization pouch - reach out to Matt at Lions Mane though he would appreciate some feedback and can make custom orders if it’s in his wheelhouse
@@FreshfromtheFarmFungi Yeah, I was just watching this and wondering if there is any reason I couldn't make my own DIY version of this lid that would fit on a mason jar. 🤔
Gary, I would love to see a video of recovering a culture which is contaminated into pure mycelium with QC to prove it. We ran into some recent issues and lost a bunch of cultures which we'll need to re-purchase or somehow recover via plating and maybe antibiotic cleansing - your thoughts on this are really greatly appreciated! Mush love
Neo Geo There are many methods for recovering contaminated mycelium - I prefer to just restart with fresh cultures as it introduces lots of potential to spread unwanted contaminants. I do not like using antibiotics for many reasons but mostly because it is unnecessary with proper techniques. This raises the importance of backup stock cultures 👍🏻
A lot of times it appears as the mycelium has over taken contam but often times it will comeback down the road in the process. It hasn't happened every time but enough that I agree with Gary... I prefer to not wait it out and possibly lose it. I would start over and keep that sample too if you want to see how it fairs. But in my experience somehow it has a way of returning.
Hey! Love this video, the media extractor, and your technique. Are you using a vertical hood? Are there specific qualities I should look for in a honey? What size test tubes do you use for your slants? What type of tissue culture/solution was in the vial you used to inoculate the honey LC and how big was it?
I have the best honey on the planet gary, u was wrong about that, i got American holly holly, and tupelo honey, the tupelo is green, and has a different kinda sugar than all others, u can freeze it , and it stays liquid, its the only 1 that doesn't crystallize when chilled, and the holly honey is clear, but ive never saw it 4 sale, i only had a small amount of that 1, but i ate it all, its 2 rare 2 use with lc!.
Hey Gary! Once again, another super video. I am all about QC, that being said, would you share which of the blood agar plates you purchase from Hardy? There are a lot of them. Also the one you use specifically for salmonella and coli?
Referencing to when he says use just honey : Use whatever broth for the LC you want and whatever works best for you, you're not gonna be able to see contamination anyways and you should always be running agar before you noc anything
Hi Gary. Nice video. I like watching your videos. Please at what intervals do you mix your LC on the mixer. And how long? Sorry for translation. I'm sending you greeting from Slovakia. I wish everyone well.
thanks for watching! I usually mix once a day for a minute or 2 at the least and sometimes longer to break up larger growth. It can keep mixing as long as it is sterile it won’t harm the mycelium. MUSHLOVE
@@AspireBlack It really depends on the strains and genetics of the mycelium being stored - I prefer to store genetics on slants long term. But in LC cordyceps will last the shortest before degrading and some species like reishi can last for years.
Thanks for all your videos. What do you think caused the contams for your Cordyceps LC? 90 minutes at 15 psi was too short? The slant culture? Honey? How do you keep from being paranoid and losing your mind trying to locate the source of the contamination? Would you have had more confidence if you hadn't been making a video. Are you confident the media extractor isn't picking up bacteria with that hanging port?
The contamination probably occurred from poor technique by me during inoculation of the culture into the LC (yeast or bacteria from my skin probably dropping into the vessel - just takes one viable cell to enter the bottle and multiply exponentially). The best way to find out where or when is to leave out blanks or let the LC rest at room temp for a few days before inoculating. It should remain clear if it’s sterile and will plate clean. The original culture was clean because the next round worked fine. There is always human error in mycology however small or rare, which requires a lot of patience and monitoring and trial and error 👍🏻 MUSHLOVE
I’m wondering if I am the only one concerned that you just pulled the tube from the Cordyceps jar and placed it directly into the morel jar? Wouldn’t their be Cordyceps mycelium in the tube still.. and also, isn’t that running the risk of transferring a possible contaminant from one jar to the next? How much are these extractor tops? Seems like it would be better to have one for each jar.. or am I over-thinking it? Regardless.. great video. Thanks for sharing.
Thanks for watching! I think they take pre-orders on their site : ) Also, we purchase our QC plates from hardy diagnostics (that way they are third party tested and certified) but they are made the same way as any other media - MUSHLOVE
dude, thanks so much man. such a great video, no one has made such a in-depth tutorial about liquid culture. why am i not using that extraction technique!! idk if you'll read this but can i ask what is your job title?
Hey thanks for following along! I am a mushroom farmer, scientist and entrepreneur - professionally, a Medical Laboratory Scientist but have found a passion for growing food and mushrooms are my gift I embrace MUSHLOVE
I thought at the 24 min mark when you moved the extractor from one jar to the other jar. You did not sterilize the extractor. Would that contaminate the culture ? Or did I miss something
Loved your video. Do you sell liquid culture? And if so, what would it cost for the moral culture? I am just getting into mycology, and the moral is my target. I am also getting into different varieties of oyster, and medicinal as well. The only thing i don't have is the flow fan and the moral culture, but i am working on that. Thank you for your time and your video, very knowledgeable my friend!
@@FreshfromtheFarmFungi apologies for the correction, we Brits are terrible pedants. May I take this opportunity to thank you for your vids. I find them the most informative resource on practical mycology on YT. Keep up the great work!
I would love to hear a follow-up review or comment! Are you still using the media extractor? Also, after the jar is done, is it easy to sanitize and clean the tubing?
yes I use these still Im making another video with a new ad-on but they are easy to clean I replaced the hose about twice a year because it gets loosened
Hi Gary. I didn't see a cap on that media luer lock connector and I did not see you spray it with alcohol before connecting your sterilized pipette. Any insight into this. Was something missed in editing? Thanks.
it was in the flow hood and this was before matt added caps to that contraption- there is a back flow valve so any fluid only went from the check valve forward. Not ideal but it worked
Hi Gary I am starting to use these media extractor bottle setups and have a question- at 19:00 in you take OFF the lid to re sterilize- why?? Isn't the point of these lids to have to NEVER take the lid off? Are you concerned about the liquid in that extraction tube sitting there? I am wondering because when I PC my bottles with these lids on (and not screwed TIGHT just loosely on) that tube will fill up, and I am wondering if I should be concerned with that tube sitting full like that long term?
Im going to do a followup video on these after a few years use - I took the cap off to clean it thoroughly so I could run another batch through it - they get clogged with mycelium over time and it’s better to stay ahead and keep it clean before it gets plugged. Sitting full shouldn’t effect it as long as it was sterilized properly 👍
May I buy MOREL liquid spawn? Can you send to THAILAND? If posible please give me the price+shipping and payment method such as Pay pal or Western union. Thanks
Back with another question for my Fungi Guru😊 Question number one when pouring agar into Petri dishes I'm assuming the steam on the lid is from my pouring it in too hot and I should let it cool more unfortunately I already started the process so I just turn the lids upside down for about 10 minutes and then flip them over. What negative effect does the moisture have inside the Petri dishes? Second question and I'm sure you probably made a video of it already if so please just tell me the name and I'll go watch it LOL but the question was what is liquid culture made from and why can you store it so much longer than agar Petri dishes
Condensation isn’t a huge deal you can let them dry out in front of a hood - the LC is made from honey and water 👍 It’s a 3d matrix compared to a 2d plate so sustains longer growth
it can work but the grain is round and can hide contams while the agar is flat so any contams will be visible which makes it cleaner. Both can work but agar is preferred
I screw it tight and make sure there is headspace for fresh air then when mixing in the hood take the cap off to allow for air exchanges. They make these lids with a filter patch as well
@@FreshfromtheFarmFungi I see. so you mean enough headspace is the key correct? I would like to try growing a smaller culture in 50 mL tube as a seed culture of bigger bottle. I guess it can be done. Thanks
@@FreshfromtheFarmFungi if the tube screw tight for several days with a lot of head space, (80%), do you think it would be okay to leave it unopened for several days until the cultures fully grown?

Thanks for watching! I think they take pre-orders on their site : ) Also, we purchase our QC plates from hardy diagnostics (that way they are third party tested and certified) but they are made the same way as any other media - MUSHLOVE
I use raw honey for cultures. It works way better than malt extract.
Use both 😊
dude, thanks so much man. such a great video, no one has made such a in-depth tutorial about liquid culture. why am i not using that extraction technique!!
idk if you'll read this but can i ask what is your job title?
Hey thanks for following along! I am a mushroom farmer, scientist and entrepreneur - professionally, a Medical Laboratory Scientist but have found a passion for growing food and mushrooms are my gift I embrace MUSHLOVE
Please tell me what’s the name of that first gel and the second one? Liquid culture process
Hi gary what type of tubing did you use for your LC? I heard some type are permeable.
Love the videos Gary! Thank you 🙏
I thought at the 24 min mark when you moved the extractor from one jar to the other jar.
You did not sterilize the extractor.
Would that contaminate the culture ?
Or did I miss something
Any luck on the morel growing ?
You meant grain spawn......also a Injektion port on the jars would be good
Loved your video.
Do you sell liquid culture? And if so, what would it cost for the moral culture?
I am just getting into mycology, and the moral is my target.
I am also getting into different varieties of oyster, and medicinal as well.
The only thing i don't have is the flow fan and the moral culture, but i am working on that.
Thank you for your time and your video, very knowledgeable my friend!
check out our ETSY store FreshFungi! MUSHLOVE
Hi Gary, you seem to refer to syringes as pipettes. There is a difference between the two I believe.
yes, there is
@@FreshfromtheFarmFungi apologies for the correction, we Brits are terrible pedants. May I take this opportunity to thank you for your vids. I find them the most informative resource on practical mycology on YT. Keep up the great work!
Brilliant
I would love to hear a follow-up review or comment! Are you still using the media extractor? Also, after the jar is done, is it easy to sanitize and clean the tubing?
yes I use these still Im making another video with a new ad-on but they are easy to clean I replaced the hose about twice a year because it gets loosened
Hi Gary. I didn't see a cap on that media luer lock connector and I did not see you spray it with alcohol before connecting your sterilized pipette. Any insight into this. Was something missed in editing? Thanks.
it was in the flow hood and this was before matt added caps to that contraption- there is a back flow valve so any fluid only went from the check valve forward. Not ideal but it worked
@@FreshfromtheFarmFungi thanks for the reply!
Hi Gary I am starting to use these media extractor bottle setups and have a question- at 19:00 in you take OFF the lid to re sterilize- why?? Isn't the point of these lids to have to NEVER take the lid off?
Are you concerned about the liquid in that extraction tube sitting there? I am wondering because when I PC my bottles with these lids on (and not screwed TIGHT just loosely on) that tube will fill up, and I am wondering if I should be concerned with that tube sitting full like that long term?
Im going to do a followup video on these after a few years use - I took the cap off to clean it thoroughly so I could run another batch through it - they get clogged with mycelium over time and it’s better to stay ahead and keep it clean before it gets plugged. Sitting full shouldn’t effect it as long as it was sterilized properly 👍
@@FreshfromtheFarmFungi right on man I look forward to seeing that, and thanks for the quick reply! cheers!
Hi, so you don't use Peptone any more or don't think you need it...interested to know...thanks!
Love the importance of QC. What’s the rate of liquid cultures that have failed at the QC point?
It varies throughout the year because of environmental patterns but usually 3-10% is average for me
What is the syringe you are using to draw out the liquid? What mls but also tip size (1/4?) What are the complete specs on the glass pipette???????
I'm not sure it came with the setup - Lion's mane equipment and supply store in Denver has the info on that
What about an extra long needled syringe that can be reused and re-sterilyzed. Does that exist? I will have to look..
awesome. im excited for you LOL go for it!!!
How much rice per Lc do you use? Great content btw thank you!
When will it be back in stock
How come the grain jars you don’t have the self injecting port or a gas exchange filter disk?
the lids flipped like this and the threading is enough space for fresh air exchange
Bees 🐝 and mushrooms 🍄 ❤️
I'm working on getting my family started on both. Can't wait to try using our own honey in our liquid cultures one day!
could you make a video on how to make those lids for the media bottles?
matt from lions mane equipment and supply in denver makes them if you reach out he might be able to help 👍🙂
Dude what happen to your flow hood? Cracked and broken? 7:24 Prob the cleaning chemicals and fatigue??
It’s the combination of bleach and the heat from substrate bags - Im in the process of fabricating a stainless steel housing
4-5 days of cooling to room temp?
Is there a reason that you need to use these media bottles for LC instead of just using ball jars?
no but the openings are smaller, so less chance for contams
Try highland honey tim brod is the owner his company is located in the Boulder Longmont area
Heck yes
May I buy MOREL liquid spawn? Can you send to THAILAND? If posible please give me the price+shipping and payment method such as Pay pal or Western union. Thanks
Back with another question for my Fungi Guru😊
Question number one when pouring agar into Petri dishes I'm assuming the steam on the lid is from my pouring it in too hot and I should let it cool more unfortunately I already started the process so I just turn the lids upside down for about 10 minutes and then flip them over. What negative effect does the moisture have inside the Petri dishes?
Second question and I'm sure you probably made a video of it already if so please just tell me the name and I'll go watch it LOL but the question was what is liquid culture made from and why can you store it so much longer than agar Petri dishes
Condensation isn’t a huge deal you can let them dry out in front of a hood - the LC is made from honey and water 👍 It’s a 3d matrix compared to a 2d plate so sustains longer growth
Thank you for the video. How do you make blood agar plates and green plates? What is there except for agar and water? Thank you.

Where did you buy the extractor? Mushlove
Lions Mane Equipment and Supply in Denver 👍
How's you're morel projects going? 🍄♥️
If you have the right Hardwoods around your place try inoculating the roots with your Morchella spawn
lots of aspen and oak
@@FreshfromtheFarmFungi target your aspen for sure!
What size pressure cooker do you use?
hey man big fan, is there somewhere where i can contact you personally? id love to talk shop !
email me
Can you tell me what you need to make mushroom juice?
Is the blood agar required or could you do the QC with potato flake agar?
potato is fine
What’s the first gel & second gel please let me know
Thank you!
Where is the water?
is the air exchange of the spawn jars from lids upside down and loosely screwing the bands on?
yes it doesn't require much at this stage
Can you please specify the types of QC agar you are using their names I cannot transcribe and find of hardy s website.
ua-cam.com/video/iHYBu3rXHes/v-deo.html
Is it a bad idea to put a single piece of grain spawn in a liquid culture jar? Or is it a must to start LC with agar?
it can work but the grain is round and can hide contams while the agar is flat so any contams will be visible which makes it cleaner. Both can work but agar is preferred
@@FreshfromtheFarmFungi thank you, I was debating it but now I'm gonna give it a go.
how long can a master liquid culture be used for commercial production? how long before you throw the master liquid culture out and start a new one?
It depends on genetics, nutrients, sterility etc. some can last years
Ah awesome
Hello. Nice video. So I wonder if you keep the bottle cap tighly close, not allowing gas trasnfer during lc incubation?
I screw it tight and make sure there is headspace for fresh air then when mixing in the hood take the cap off to allow for air exchanges. They make these lids with a filter patch as well
@@FreshfromtheFarmFungi I see. so you mean enough headspace is the key correct? I would like to try growing a smaller culture in 50 mL tube as a seed culture of bigger bottle. I guess it can be done. Thanks
@@FreshfromtheFarmFungi if the tube screw tight for several days with a lot of head space, (80%), do you think it would be okay to leave it unopened for several days until the cultures fully grown?
