Agar vs. LC (Liquid Culture) Cultivating mushrooms and using different media to grow mycelium

One of the best comments on KZbin! 🙌🏻

[@BIBIwood]

As a hobbyist, I find it harder and harder to justify my use of LC. LC is great to quickly multiply your mycelium to inject vast amount of grain, but that's not a situation you encounter often as a hobbyist. If you are going to do LC properly you need to use agar anyway: you will inoculate your LC with agar, and you will want to test each of your syringe on agar for contaminations. So I find it easier just to skip the whole thing and just transfer the original plate on additional agar, and chop those plates in halves or quarters to directly drop them in the grain jars.

[@FreshfromtheFarmFungi]

yes it is for fast multiplication - some species take forever to grow like bluefoot, king stropharia etc. and using Lc saves a TON of time which helps with beginners and impatient folks like myself ha 👍

[@HeyHeyHarmonicaLuke]

I've been reaching the same conclusion, I've made 6 LC jars now but haven't used more than two 10ml syringes from each. Soon I'll try agar to grain

[@Sssanbo]

So much happier not using LC. Had some terrible results. I can go from agar to grain just fine .

[@FreshfromtheFarmFungi]

@@Sssanbo this is interesting to me and makes me want to ad more plates to my shop thanks for the feedback everyone!

[@Dewey_Boondye420]

@@HeyHeyHarmonicaLuke if thats the case you could probably skip it all together and just use grain to grain.. add a few colonized grains to your uncolonized grains. maybe clone the genetics you want on agar once then colonize a jar and from then on out gtg would save an extra week or two. if ur just growing small amounts as a hobbyist none of this is really needed.. i like lc because weather i use it or not i can keep a jar of each of my best genetics in the fridge for years.. i like to have lc for keeping my genetics.. spore syringes/prints for backup. i mostly mess with the lc though cause its faster and you can see if theres contam.. best of luck! mush love to ya!

This is really great info. I'm just moving into the LC and agar medium and moving away from spore syringes. Having good quality information like this is priceless, thanks.

[@FLORIDAMANIAM-he2lz]

Spores syringes are awesome for finding what you want. They are a shotgun blast of genetics

[@jefolson6989]

When I got interested in growing I bought a kit that claimed it had everything I needed and it was fun and easy. And a spore syringe. I didn't use half the things in the kit and didn't even hear about LC until I had failed several times with spore to spawn tech as instructed. LC opened the doors to finally have some decent flushes. There is much misinformation in the mycology arena. There will always be variation in methods etc but it seems like there is also on purpose elimination of essential facts. Certainly there was from the company I bought the kit from. Everything could have been purchased at home depot or the 99cent store for half the price. And those who sell spores don't want you learning about liquid culture because it hurts their business. The whole spore to spawn, especially Uncle Ben tech is in my opinion the worst practice promoted to the public. Serious growers discover that fairly quickly and hopefully learn about LC and agar work. I should have bought the book first. I wouldnt have purchased the kit. But thats the usual way. First the sins , then the bible.

[@JubeProductions]

@@jefolson6989 those kits aren't too bad for an individual that isn't interested in learning about mycology and just want the quickest way to grow shrooms so they can trip balls on Friday night. There is a market for that, and those people don't want to take the time to understand what they are doing and to get those supplies themselves. The problem is when people want to learn about mycology, and they buy these kits, then fail miserably, they don't continue. They give up figuring it's a scam and it's going to be too hard. I was more interested in learning about mycology than getting high. I took the time to research everything, and get a solid understanding of how to grow, before I attempted my first grow. I used spores syringes with the PF Tek. The first time I did it I followed the steps exactly, without any adjustments. I did this in order to gain a solid foundation into mycology. Once I had that understanding I was able to experiment. I changed things and found what worked and what didn't work. I had many more successes than failures. But even with failure I still gained experience. I don't grow on a commercial scale and I only do it for the fun of the hobby. The fruits are just a bonus, that can help me with my own personal insight. I use psilocybin to better myself and my understanding of my position in this world. I wish that it wasn't illegal and more people grew mushrooms for the fun of it. I wish the knowledge was easier to get and more people weren't deterred from the hobby. I also wish more people were able to experience the benefits of psilocybin, not just for a good time, but as for a tool for self improvement. It's so strange to me that it's illegal for me to cultivate mushrooms on my own and invest them as I see fit. This is something that is here in our world for a reason.

So I came across a video last year of someone putting a silicone tube in their LQ when they made the lid. I believe the tube was just attached to a 1 way valve and then was red siliconed to the lid just like the filter is, and the tube went to the bottom of the jar. And then they could attach a 3-way luer lock valve along with a syringe when they're ready to inoculate. Then they just suck up the LQ in the syringe, twist the valve and push it through the 3rd way to the spawn bag. It looked very productive and time saving but unfortunately I can't seem to find it again, just wondering if you've seen the same thing or anything similar.

I have noticed with my chestnut mushroom liquid culture it is not totally clear compared to my others. The other jars are crystal clear with blobs of mycelium. Took a fresh piece of agar and grew it out and made another liquid culture and got the same thing. But both produce mushrooms with no contamination. It seems like some of the mycelium do not like to socialize and just stay suspended making it a little less clear.

[@FreshfromtheFarmFungi]

it could be a polyploid or two cultures but pholiotas can be weird and spontaneously mutate at the leading edge. They are strange indeed

[@OracleofOcala]

[@The_Inca_Stargazer]

Personally I don't use liquid culture. I only produce enough mushrooms for me and my family, liquid culture seems to be more for volume producers. And agar doesn't add any more water to my sterilized substrate, I work real hard to get my grains hydrated and dry. Liquid culture adds back too much water. I can add agar pieces from an entire plate and it won't change the hydration level at all. But if I were inoculating 100 bags of substrate I can see the advantage of using liquid culture vs. dozens of plates of agar.

If it is possible to put quarters from separate cultures together… let’s say two different oyster mushrooms in on dish and then take a culture from where they come together… grow it out put it to spawn… will that produce a hybrid if fruited? I understand that you would have to isolate the spores from the grown fruit and do selections to gain from the hybrid… but would it be a hybrid, and could you do the same thing in liquid culture?

I am a little confused about the honey. I heard that already a few times but still have questions. In honey one of the only spores of anything that can survive in it are from the bacterium Clostridium botulinum, which can cause botulism. That can get fatal really fast. I'm sure you can get rid of the spores and bacteria, but improper sterilisation puts people at risk, doesn't it? If it's not, I would love to hear from somebody with much more knowlage than me why that's the case. And if it could be a problem maybe a disclaimer would be nice to have.

[@FreshfromtheFarmFungi]

clostridium is ubiquitous in nature and present almost everywhere in the soil and is why it’s so important to sterilize your culture media just like canning vegetables. This honey solution is diluted and sterilized and clearly supports the growth of the fungi being cultivated along with many other organisms like yeast (mead is made from honey). Also, this solution is just a media for the mushrooms to grow to transfer onto grains or other substrates. Quality control the media on agar to ensure sterility - all of this info is covered in my channel. There are a lot of people doing lc’s in the industry and I am very careful about ensuring quality control and try to make that clear.

yes try the vendor “nothing but air” on instagram he refurbishes flow hoods and has good deals and sometimes gets smaller ones - also hood ratz I believe makes 2’ x 2’ ones or look on etsy - these are usually hand made and sometimes do not work as well as professional engineered ones

[@ranjanty]

Gary if I was to make some spawn plugs with LM and insert into hardwood logs now (Jan 5th) will the next freeze kill the mycelium? I read that it can take up to 12 months for that to work.

[@FreshfromtheFarmFungi]

It may kill them, I would wait until spring and you should get fruits by fall but why not try a couple anyway and see what happens they have amazed me before with resilience

[@ranjanty]

Please can you answer this Q, can i use Regular white sugar in this media Like PDA using Sugar or honey insted of dextrose glucose, and what the ratio would be? Thank you

[@FreshfromtheFarmFungi]

I never tried sucrulose but it might work start at 1% and work your way up from there I don’t recommend going more than 4%

Why do people add yeast to pda and what are the beneficial differences between PDA and and MEA?

[@FreshfromtheFarmFungi]

for nutrition - there are micronutrients in the yeast and different sugars between these two recipes

[@mskinetik]

What size needles do you generally use?

[@FreshfromtheFarmFungi]

I usually use 14g or 16g depending on the thickness of the mycelium

[@grounded7362]

When making LC would it be okay to use a Microppose Synthetic Jar Lid Filter Discs with a Adherable Injection Port? Or would the filter size be to much for growing LC since the entire lid would be filter? This is all I have at the moment.

[@FreshfromtheFarmFungi]

it might work ok for a run or 2 but it will start to deteriorate over time and is risky long term

[@FLORIDAMANIAM-he2lz]

A lid with two holes works fine . One hole with rtv as an injection port and the other hole with a piece of filter disk rtv sealed to allow sterile gas flow. I end up using the jar before anything falls apart . Then i just reuse the lid and make a new port and seal a new filter disk.

[@gowthamshetty5674]

Bro can we directly introduce liquid culture to the woodchips/rice straw substrates? Please help me

[@FreshfromtheFarmFungi]

yes it can work but you need to pasteurize the substrate or the nutrients from the liquid media will get consumed by contaminants quickly

[@maxplank3782]

Can you reuse a syringe by sterilizing it with alcohol?

[@FreshfromtheFarmFungi]

it wouldn’t be completely sterile - some endospores could survive but it might work well. I used to soak the rubber stopper in disinfectant overnight and sterilize the plastic in a pouch in an autoclave that works really well but now I use glass syringes whenever I can and those can be autoclaved hundreds of times 👍

[@tyo6896]

I fill with alcohol, and also leave the needle submerged in alchol... I hope it's killing those spores cause I just did some LC transfers and spore to agar... I'm new, so I can't vouch for effectiveness.

[@jefolson6989]

I believed that , logically , one should be able to innoculate LC directly to substrate but I dont think its ever been done. LC , IMO, makes the grain too wet, and causes mold and rot before full colonization. Forget Uncle Bens! The rice is already over cooked for our purposes. Adding more liquid is a disaster. So I went back to grain jars, innocd with small ammount of LC. It works but not tremendously fast.

[@FreshfromtheFarmFungi]

I have gone straight to bulk from Lc it works but isn’t ideal for my space because I quickly fill my incubation room with mostly uncolonized substrate. I will be doing a video soon to try to mitigate this issue. But yes, under-saturating in preparation for lc is going to give better results

[@FLORIDAMANIAM-he2lz]

I have innoculated hundreds of lbs of substrate with liquid culture.

[@jefolson6989]

@FLORIDAMANIAM-he2lz cool. Your own substrate right? The uncle Ben method never worked for me . And some reccomend spore to spawn directly into Uncle Ben bags. Just too wet to start with.

[@rafals5113]

How long can I keep liquid culture in room temperature?

[@FreshfromtheFarmFungi]

as long as it remains sterile some can remain viable for months or years they will form a layer at the surface like a scobi

I cant get rid of l.subtilis ! So bad How can the mycelium breath in liquid culture shouldn’t it be able to breathe oxygen in ?!

[@FreshfromtheFarmFungi]

there is a .22 micron syringe filter that is built into the lid for gas exchange - you need to plate and subculture from the leading edge until the contamination is resolved and no longer present (the mycelium should outrun the contamination)
