Stones question

Im just growing out a culture of Psi Mexicana to grow some stones and shrooms.
I want to use a 2 quart bottle to try a stones grow and wondered if:
-Do they have a history of stalling
-Should I use a wedge, grans or a LI

The big jars have issues going anaerobic in the center...what variety of me you got I know jalisco doesn't make stones well but fruits great...the a strain does the opposite
--------------------
  It doesn't matter what i think of you...all that matters is clean spawn I'm tired do me a favor

In the book GGMM Stamets recommends lower moisture content for larger jars because of this. I feel stones can do with more moisture, I am pretty sure RR recommended lower moisture for stones though. But in some old thread I was asking about higher moisture and some respected user like Workman agreed, I might have suggested a mixture with some well hydrated rice to supply a water supply. I know the old sporeworks "philospophers bags" seemed to have quite a high moisture content. I had rice grow with only tiny stones produced but it did well growing stones when mixed with quite moist coir.
Most stone producers create most stones at the interface of the glass and grains, so small jars might get a higher yield per gram of grain. ATL#7 create stones throughout but mexicana is one which does have growing more up against the glass. Some people doing bags will lay them out flat because of this, so you get more stones at the surface.
I have also wondered about adding additional moisture during a grow, injecting sterile water. When harvesting you can see grains totally dried out.

So I think im going to drop a wedge into a pint jar and do some grain to grain as I want some musies too. Gunna try a 1q and 2q jar for stones. Just found some quart pp5 plastic boxes so gunna bottle tek those.
You can use the grains after u harvest the stone too right?

Yes you can spawn the grains after

I like using bags. Averaged 17 dry ounces of stones per 5 quarts grain in bag with a dozen bags. Plus, they are so much easier to harvest than jars. This last run of bags I did I simply used an lc. Took about 10ish days for the entire bag to colonize. Now I'm waiting another 5 months to harvest.

Workman said he increased the temp at the start when growing ATL#7 to get it to colonise quickly. This seemed to be just to speed things up, and these days many people would advise against this as it would increase the likelihood of contams growing. Once colonised he would drop the temp. But maybe quick earlier growth allows earlier shaking before stones are forming and might be a good idea.
You can keep your grains purposely dry and add shitloads of LC, I have done this in the past with stones & cubes. I think it might be more beneficial with stones as I do not like the idea of shaking them as stones can by trying to grow from the start.
In this thread I added loads of LC to a large jar. In hindsight I know my jar had far too much moisture, a jar that size should have far less moisture as it risks going anerobic, as cronicr said earlier. But it did colonise quick. I was also using spores direct to LC and the low spore producing strains are probably more likely to have more contams per syringe.
The jars look fucked early on, but that is fairly typical of stone jars.

Uninoculated Philospher's Bag - Consistancy is like modeling clay and appears to consist mostly of rice. Syringe passed through the injection port and easily into the substrate. When the inoculate was added it flowed out of the substrate and into the space between the substrate block and the bag. I used a full 10 cc syringe since I had it available and I wanted to speed things up. A few spots of growth on the surface of the substrate were visible in 4 days at 85F and quickly spread. It reminds me of mycelium growing on the surface of an agar plate.

I don't know about the mixing. Maybe you shouldn't. But you are incubating at too high of temperature for quality sclerotia. I am incubating at 85F just until I see the start of sclerotia (to speed full colonization) and then lower the temperature to room temps 68-72F by bringing it into the kitchen. I just put them in a brown paper bag on a shelf and leave them alone. I have noticed that overly high temps causes excessive buildup of metabolites (yellow mycelium piss) and that can't be good.
At 13min 59sec you will see a commercial operation in the netherlands allegedly incubate at 28C/82.4F, which is possibly only at the start too. Alleged growing capability of 18,000 tons a year.
at 14min 50sec they are cleaning them with water.
