Hey shroomery community. I'm facing low yields in my grow room right now (P. pulmonarius) and I can't fathom why. I have grown P. ostreatus and Hypsizygus ulmarius before with no problem, great yields. Perhaps its just the strain but I thought you all might have some input. If you could refer me to some other useful threads, too, that would be fine.



Below are some pictures of my current flush, pretty low tech. The bucket is straw, cardboard with a little gypsum. The bags are straw and gypsum. Both are inoculated with sawdust spawn. This is day three after pinning initiated and the caps are starting to flatten out. They aren't aborting, they just aren't growing as big as I expected at all. My assumption is that my problem is due to a lack of nutrients. My humistat reads 78 because I am flushing the air. I do a full air exchange about 6 times a day and mist the whole room afterwards to bring the room back up to 90% humidity. The temp stays around 70. I'm ordering a timer and a mister this week. I'm also getting ready to set up a separate colonizing room to have better control over the cycles but I'm not ready for that yet. Please ask if you need to know more details.

Consider asking a mod to move this thread over to Gourmet & Medicinal Mushrooms, where you'd likely get better responses.



To my knowledge, P. Ostreatus is not all that fond of straw. Have you tried any type of wood substrate - chips, fuel-pellets, or even sawdust?



Edit: Ignore my question. I was skimming your post and assumed, by the title, that you were using pure straw as your substrate.



Edit #2: Okay, so, upon further reading your post, I do want to mention that some cultivators have had very hampered success with oysters even with indoor conditions as aerated as yours. The oysters are very demanding of FAE.



Otherwise, you could curry some insight if you explained your entire process from the spores to now, but I'm stuck on the FAE possibly being the issue. Wait and see what another user says.

they all love straw, they actually perform astoundingly well on straw.



from the looks of the fruits though your fruiting conditions are piss poor and that's why.



looks like way way way too low FAE and too warm for that species



you should look in gourmet mushrooms, this section of the forums is for actives.

Thanks, how do I ask a mod to move it? I thought Mushroom cultivation would be a good place but is this forum mainly for psychedelics?

Thanks for clearing that up, Bod. I always thought their ideal was wood substrates. I'll have to take some better notes before I get into edibles.

Bod, You think CO2 is too high even though the bags on the shelf are producing more poorly than the bucket on the floor (implied: CO2 sinks)?

This forum is used mainly for psychadelics...but not limited to it.



This is a mushroom cultivation forum.



People say to post over in the Gourmet section only because the really knowledgable people with gourmet and medicinals hang out over there.



Not everyone is cool with psychadelics over there, so they hang out over there.



But listen to Bhodista. Its your fruiting conditions.



You need way more FAE.



Think turbulence when u think air for oysters.

Both like hardwood sawdust, and both can be fruited out of jars, but performance is better with a larger substrate. Oysters do very well on straw as well. You can use quart jars to pressure cook some sawdust, and then when the grain jars are fully colonized, spawn them into the sterilized sawdust and fruit out of the jar as in the first picture below. The second picture is a laundery basket with several quarts of oyster spawn mixed into about 1/10th of a bale of pasteurized straw. The third one is Lion's mane on a sawdust/woodchip block that was sterilized and grown in filter patch bags. You can also grow oysters and lion's mane on newspaper or old phone books the way this reishi is growing.

Get the idea that CO2 sinks out of your head. It mixes with air it does not sink. It will sink in huge valleys not in a room. I work at a brewery with literally 10,000 gallons of beer fermenting and the co2 exits through 5 gallon buckets at an astonishing rate, we don't suffocate even in the winter with the doors closed.

Also, definitely don't colonize in the same room as you fruit.



Fruiting oysters is a tricky game when u first start. Gotta keep your humidity high and your air exchange constant.

You want holes all around to create circulation. It's a myth that CO2 settles to the bottom and needs to be 'drained' out. If that were the case, we'd all be dead from the CO2 from the power plants, car exhaust, etc. sinking to the surface of the earth, but the fact is, CO2 can be measured in the highest reaches of the upper atmosphere. It simply mixes in with the air and goes where the air goes.

If CO2 was heavier enough than air that it settled to the bottom, we'd all be dead from CO2 poisoning on the surface of the planet. CO2 mixes with the air. To get rid of it, you exchange the air in the terrarium. You can't simply drill a hole in the bottom and expect it to run out like water. CO2 is found high in the atmosphere, not just at the surface. It's the same in your terrarium. In a completely airtight container, the CO2 would sink to the bottom. Such is not the case with our growing containers.

You have my thanks for finding that quote. So, wood and straw are quite viable.



As well, this board has a bit of a misnomer to it, but you will indeed get more extensive results on that board, OP. I haven't had to use it yet, but there is a function on the site to message the modifiers to request a thread's transfer to another board.



I'd simply PM a mod, if it came to be necessary.



Are your outdoor conditions viable for oysters? There has been well-documented success of outdoor grows for oysters even in surprisingly cold regions. Excess warmth, however, I'd work cautiously around.



Post Extras:



Okay, thanks everybody! I'll try and get this thread moved. I apologize for my lack of understanding in that respect, I'm not really a computer person....



When I was cultivating Elm oysters and P. ostreatus in coastal North Carolina, I used straw (and logs) but I could just put them outside and mist it once and day and they'd be fine, 70%++ relative humidity. But here in Colorado its only 30% on a good day so tweaking an indoor space to make it happen on a budget has been an interesting challenge. I'm consulting with someone here on the western slope growing oyster bags on sawdust in a root cellar with passive ventilation that naturally stays at 55-65 degrees, 50% humidity with constant air flow. I gotta build me one of those.



Thanks, again

oysters are not to picky about their substrate, they've been cultivated to digest crude oil even.



oysters love low temps and lots of air, the humidity thing is a bit of a trick but i'm sure you can find some clever things to do outdoors if you look around long enough,.

Also, I was under the impression that if CO2 was high, they would stretch as if they were looking for sunlight. They haven't done that, they have a normal shape, just small....
