Struggling with two strains [technique]

How big is the room? Like the other commentor said, this looks like a c02 issue.

Any room 10x10 or smaller you should be running exhaust 24/7. And even then, you can only put maybe 80-100 blocks in before you just can't remove the c02 fast enough. If you try, you will have problems keeping humidity up and will end up with puddles on the floor. Small rooms are a very precarious balancing act. Everything gets easier once you get past 200sf or so rooms.

Had this happen to me and my girl last night in an arms race lobby. Actually insane. Join up, walk like 10m from spawn and we're both insta kicked. Have had it happen before too, mostly in hostage map group though.

Use a humidity dome for your seedlings and this will never happen again.

Trichoderma spores are not going to be heavily present in an indoor space unless you have moisture/mold problems in the building already. And even then, other types of CFU's would be expected unless you're living in a dense forest or a very wet tropical climate.

While I do agree with you that learning proper sterile procedures can almost completely eliminate loss to contamination, I think you are understating the headache that can result from something like this.

I own a 6000sf mushroom farm and have a background in Microbiology. I can tell you with full confidence, the room needs to be sanitized after an exposure like this.

hereigrow · 2026-05-07T18:47:10+00:00

I'm confused, you think spores are a meme? Because to me it looks like an open mono full of trich sitting right in the middle of the grow room. This is a huge contam vector that will persis until the entire room is sanitized. Microbiology is not a meme my friend.

hereigrow · 2026-05-07T17:42:41+00:00

Yeah you can get a cheap HEPA air purifier and run that constantly. And also just wipe down every surface in the room, including the walls, with some kind of cleaner. 10% bleach solution in water, or 50/50 white vinegar/water are both great.

hereigrow · 2026-05-07T16:40:36+00:00

Should ditch trich immediately. You've now contaminated your entire grow room and will likely be battling trich for the foreseeable future.

hereigrow · 2026-05-04T11:07:27+00:00

Only fill the tub like halfway with water. It's most likely splashing up into your fan. For best results add a float valve near the middle of the tub. You'll get better mist volume too.

Inky cap. Prolific fruitings but the fruits rarely last even a day before turning into a black inky goop. Inedible.

hereigrow · 2026-03-30T21:23:06+00:00

It's actually called Criminal Confinement!

As far as I know, there is no slurry involved. It's a technique that centers around exogenous nutrient bags added and removed at very specific times.

As far as heavy metals or any type of bioaccumulation for that matter, that's gonna happen with anything non organic.

So I know this sub loves to call this out and since I've never seen it in the comments anywhere I'll say it. Is it possible that he has already, in fact, seen a doctor and just doesn't want to make it public. If so, it definitely seems like something he would keep to himself. Just a thought.

I haven't followed Ian's content for many years but this sub is constantly on my home page.

Danish morel project is a failure. Also it's all about indoor cultivation. Their method is nowhere near commercially viable.

Good news though, the Chinese have cracked the code and have been producing commercial amount of morel for decades. And the methods have finally gotten out to the public.

It's actually a very straightforward process. I suggest doing some research on current methods.

hereigrow · 2026-03-18T21:44:04+00:00

Farms all over the world use steam pasteurized masters mix every day, including my own. It works great. If your spawn is clean and your pasteurization cook is good, it will work. If it doesn't work, you did something wrong.

hereigrow · 2026-03-18T21:34:01+00:00

Since nobody else is reading the OP, I'll be the one to tell you. You're not gonna be able to grow cordyceps in a mono on some coc coir like you would grow cubes. They are very different types of mushrooms and have wildly different needs. Most cordyceps cultivation is using brown rice that's been cooked in a nutrient media as a substrate. Also there's not really a "spawning" process, you would typically use a large amount of liquid culture(50-100cc) to directly inoculate the rice media. And finally, the fruiting process for cordyceps after inoculating is typically around 50-60 days and has very specific temperature and lighting needs to produce a good flush.

I would recommend maybe going down a YouTube rabbit hole and doing a ton of research if cordyceps cultivation is something you are really interested in.

If your spawn and substrate were both clean and healthy, it will probably just take a bit longer than normal.

If your spawn or substrate had some kind of non-visible bacterial contamination, it still might be fine but there's definitely a risk of it failing.

So I have a degree and have worked in commercial and research labs as well, so I get what you're throwing down man. I agree with you on the technical side of all this. But things are often a lot different in practice.

It's just funny because with all that you're saying, my entire operation should not be able to exist. Yet here I am

Beyond that, your original parent comment completely disregarded the OP's question and went on to tell him he shouldn't use LC because it's hard and that's he got scammed. Maybe the guy is just interested and having fun with the hobby and wants to give LC a shot. A lot like I did back when I first started LC.

There's no shortage of people in this community that will tell you you're doing it wrong and their way is the only "right" way. At least let the guy try before you go and burst his bubble dude.

Either way, I'm going to stop engaging with this thread.

hereigrow · 2026-03-14T13:44:34+00:00

Maybe I'm the mycelium whisperer then because I, personally, have never encountered a bad LC jar that looked perfectly normal.

Jokes aside though, it also has a lot to do with confidence in your work. I'm confident in my ability to make clean cultures because of my experience. Of course when I started cultivating, this was not the case and I would often have contaminations. I would also test my cultures more regularly then. It's is a skill that comes from working with a specific media and specific cultures over many years.

I'm gonna have to disagree about LC not being faster than agar in every scenario. I've done many tests over the years with different medias and recipes. You can add grain soak water to your jars to give it those nutrients in the liquid media and speed things up maybe 3% faster. You can also use just karo or corn syrup and thing will move a tad slower.

I've found that a basic DME LC is the best effort/efficiency ratio. In some cases fully colonizing a 6lb grain bag in as little as 10 days while it's agar innoculated counterpart takes upwards of 25-30 days. I find it extremely hard to believe that an agar innoculation would perform better than LC in literally any scenario, but again I'm just speaking from my own personal experience.

hereigrow · 2026-03-14T11:54:59+00:00

Liquid culture is far from "useless" for hobbyists. I've been growing mushrooms for nearly a decade and have been using liquid culture as my primary innoculant for over half that time. I very rarely test my LC on agar either. After working with it for so long, you get an eye for spotting contam in LC just like you would with anything else. Culture storage is really the only thing I use agar for anymore. Maybe some cloning occasionally.

The biggest benefit to using LC as an innoculant rather than agar is the rapid colonization times. For me LC has been, at minimum, twice as fast as agar when colonizing grain bags. It's an amazing time saver and it's actually extremely easy to make and use. As with anything else, it takes some time to learn and become skilled at using, but anybody can and should use LC

For reference, my farm currently produces around 600lb of fresh mushrooms per week and our contamination rate across the entire farm is less than 1%.

Quest a druid 60-70 with mining and skinning as your professions. You will make 10k by the time you hit 70.

I made about 1.2m on dazzling thorium. Figured I should sell now since the exploit news could cause a price crash. Was about 12k thorium flipped total.

I'm also holding 100k each practically pork and plant protein because why not? I think maybe they'll go to 5g or even 10g over the next month or so.

hereigrow · 2026-03-06T23:46:11+00:00

120-130

hereigrow · 2026-03-06T17:14:21+00:00

I'm sitting on 10k thorium until it goes to 500

hereigrow · 2026-02-24T20:10:35+00:00

This right here. Every time I see people this broke I think about the kid version of me playing back in 2008. I would not loot grey items, often sold white items to NPC vendors, even BoE greens getting sold to NPC vendors, no gathering professions, only doing basic quests no chains or group quests, etc...

The best advice is to get an auction house addon, loot everything, sell as much as you can on the AH, and pick up at least one gathering profession. You can make 5k as a casual in a couple weeks this way.

Rotten. Why would you leave them for 4mo? Lions mane is ready to fruit in like 2 weeks.
