First Lions Mane and Shiitake 75

Here's my first try at Shiitake 75 and Lions Mane.
Trying to find a good tasting gourmet species for my basic greenhouse with little spore load that can grow good around the low 80's during the day without being too c02 dependent.
Tried pink oysters first last year but I absolutely hated the smell of them. Maybe the other oysters smell better, but it smells like rotting fish to me, while they grow and handling them. I dont like that their spores are unsafe either. Don't want to duct out my house or breath in spores so that lead me to Shiitake and Lions Mane.
Since I wanted warm weather mushrooms, I chose Shiitake 75, but could only find it in agar plate form, so I got one plate of 75 and one of Lions Mane. I didn't want to wait the week or two for new transfers to get done, so I just used a third of the culture plates I bought for master jars, then made a few plates and a few agar slants for each and put them in the fridge with some of the original plates still for use later on.
I went from each culture plate to 5 master jars, used 2 to expand to 10 jars, and threw the other 3 in the fridge for g2g later on, I'm just trying to get it down to try some new mushrooms and in case my agar plates contaminated I wanted to be sure I had the best outcome.
For the lions mane I used the 10 rye jars to inoculate 10 supplemented sawdust bags, with wheat bran which I bought a huge sack of.
The greenhouse I made is a cheap version of gr0wers automated one, it is just the shelf, 3mm thick poly, tarp tape, and a zip wall. Taped up like a christmas present. It was all easily obtainable in one trip to homedepot for around 100$. For the humidifers I use two ultrasonic coolmists, one on top shelf one on bottom, both plugged in to the same humidity controller, with an evaporative humdifier that pushes the air around decently with fresh air from the room going into it, I hoped it would be good enough to keep the c02 low while leaving it half unzipped and a fan running in the room moving the air.



The only downside to this style plastic shelf is once it gets covered with spores, its very hard to clean off because the plastic is textured, so the spores are there for good. Bleach or alcohol doesn't seem to do much.
The lions mane all finished two flushes within the 8 weeks of the shiitake blocks sitting.


But I never made it to full tooth development, they only got this big then some started to turn pink and yellow so I assumed they were stunting and harvested them early, I really wanted to see the long teeth, its the main reason I picked Lions Mane, I thought it was very c02 tolerant... Well it is, you just wont get the teeth. I tried it with it completely unzipped, still didn't help the second flush. After the second flush I thought they might need a dunk for a few hours which made them all contaminate with trich.
For the Shiitake 75 I searched for a recipe that someone had trial and error with already to figure out how little amount of wheat bran I needed, since over supplementing 75 will make them mutate from what I read, and also too much rye per bag, I did half a jar each (300 ml) to each bag, making 20 shiitake 5 lb blocks out of these 10 rye jars instead. The recipe for the four 5 lb shiitake bags I used was this.
-Half cup bran -24 cups fuel pellets -Half cup gypsum -28 cups of boiling water(Whatever is required for field capacity) -300ml spawn per bag
After exactly two months, I put 10 bags in the fridge for 3 days, then took them out and smacked the sides about 30 times, almost breaking the first one apart, stripped the bag then rinsed the blocks off. It seemed like mycelium wasn't as solid in the middle and some parts of the outside, but after a few days in the greenhouse the entire blocks became all white, then all brown a few days after. I still have 9 bags I was going to compare results from 3 months waiting instead of 2, and am wondering if that's why I got a little amount per block. I flipped them upside down because most of the popcorning was on the bottom of the bag, not sure if they shouldn't have been flipped or if its better that way.

 This was the best one so far but noticed some trich on the bottom, where i have it sitting on the bottom of the bag, I just stripped the whole bag off except the bottom piece for it to sit on, instead of trying to clean my shelves for hours.

Also I'm really unsure of these brown spots I'm getting under the caps, and on the stems, it kind of looks like some type of bacterial blotch, or is it just normal for shiitakes to get this discoloration? Wanted to know before taking them out the fridge to eat.


So not sure what I should do next time, if this is from still too much supplementing, just want to know what I can do to make them do better next time maybe no supplementing all together or 1/8th to 1/4 cup per four 5 lb blocks? Or to just try another strain that I don't need to worry about over-supplementing.
I'd like to know how others deal with getting the Lions Mane teeth to develop in a greenhouse like mine, because it seems like they really need constant air exchange, much more than most kinds of mushrooms. I know it needs an intake and outtake fan, but am trying to avoid making a humidifier with piping in, just want to keep it simple with coolmists inside instead of building my own humidifier bucket.

Yeah 75 kinda sucks as a strain. Not the best quality mushrooms, giant stems, probably my least favorite of shiitake strains I've grown. I would recommend trying another strain for your next go on shiitake. I always had good luck just using a whole quart of spawn per bag, and not any bran when I did shiitake, that way you don't have to sterilize the bags either, I think it's easier and I didn't have problems with mutants in any strains I grew.
Not sure where you heard lion's mane was co2 tolerant, as you've seen it's definitely not. Maybe try king oysters?

I've had some great S75 flushes and then some absolute shit S75 flushes. Tracked my sub recipes & growing conditions, but couldn't really figure out what makes this strain tick. Eventually moved on to other more consistent shiitakes. The big mushrooms S75 would produce were great for burgers though.

I'm guessing you got low yield on the shiitake because of the high temps. I don't think s75 or almost any strain is going to like fruiting at 80f.
The blotching could be from the high humidity coupled with poor fae. (Anyways they look fine to eat)
Btw even though the spore load is lower you can still develop allergies to shiitake and probably the same goes for lions mane. It is a much better practice to exhaust outdoors. Seems like you need to revamp the fae anyways, what's stopping you from putting a tube to the outdoors?

Lions mane needs high humidity with a constant gentle breeze to get teeth instead of coral. Definitely not c02 tolerant

Yeah I am surprised by these giant stems, I will try it unsupplemented next time with the couple jars I got left in my fridge, I figured 75 is the only shiitake strain I can do around 80 degrees, but I'll probably try a different shiitake since temperatures will be cooler in a few month's then. Kings look cool to grow too that's a good idea I might try those as well, thanks!

Good thing I thought I had to throw these away from the brown spots.
I just haven't got around to ordering the disc humidifiers, the exhaust ducting, pvc and two blower fans. Wanted to see if I could get away without it. The next greenhouse I make will be made that way with ducting out a window.
I had no idea it went the same for shiitake and lions mane spores. Thought it was only oysters.

Constant gentle breeze was not mentioned while I was looking up info on them, thanks that makes more sense explaining it that way. This is what I read, as well as heard in videos, so I didn't think it was going to be crucial.
Fruit Development: Temperatures between 15-20 deg C. Humidity at 90%. Ensure not to spray fruits directly when misting. Fresh air requirements are relatively low.

Was that from Stamets' book? That book is incredibly outdated.

No I do have the newer version but im not that far into it yet, I read most of the first one I know its from the 80s.
I got into gourmet after seeing a few different channels on youtube, one of those being FreshCap who has a website on growth parameters for most types as well as selling his own spawn, supplements, etc so I figured his write up on each was solid. Even said can still do good in sub par conditions so I wasn't expecting them to do worse than oysters which did pretty good in the same greenhouse.
