True, the thread got loaded with misinformation from a bunch of trolls.
I bet someone will try it, but whether or not they post it is another story.

If you order an oyster mushroom syringe from Workman you can have fruits and pictures within a month. Oyster is much, much easier to grow than cubensis, but hey, we'll understand if you're afraid to post pictures on the internet. Just something to give us a general feeling that this won't all contaminate horribly would be nice, because I'm pretty sure this will all contaminate horribly.

RR doesn't understand the physics of his tek, obviously making shit up and changing his story about the difference multiple times.
There is no nuance that allows water to be heated higher because the surrounding atmosphere is more humid, that is fucking absurd. And if there is such a nuance then point it out by name.
His tek is in no fucking way sterilizing the flour, I don't care how many disagree.
He was obviously wrong about what constitutes steam, so I wonder what else he is wrong about.

It doesn't contaminate. I'll prove it to all of you later.

Another point of evidence is that suggested temperature is 72-75 or some bogus made up shit now, when it used to be 85, and it is 85 in the real world, but the cakes aren't sterilized so the incubation at optimal temperatures can germinate the spores that weren't killed in his steaming.
Germs don't spontaneously generate because of heat. It's because they were never all killed in the first place.

There is a limit to how much water can be a constituent part of an air mix. The ratio of water in the air to the maximum amount of water in the air for any given temperature is called the relative humidity, and once you reach saturation evaporation ceases. In a pot it doesn't completely cease, since moisture is being lost as the lid pops up, but yeah, there's direct correlation between the boiling point and the partial pressure of the gas above it.
This is why water boils at a cooler temperature on mountains.
If you don't believe it, either stick a thermometer in a pot of boiling water and compare it to the boiling point at sea level on a chart and see how it correlates to your elevation (yes, it IS that documented) or boil a pot of water and put a lid on it. Then take the lid off, and then put the lid on it.

Thanks for the offer, but I can go to the store and clone one.

Water boils at lower temperatures at a higher altitude because there is less pressure, not humidity. IE: the boiling point is when atmospheric pressure = vapor pressure.
A lower atmosphere therefore reduces the vapor pressure required to match it.
the water inside the little pot that he is boiling is never going to reach 250 degree's.

I would suggest an experiment for you, put a thermometer in a cake that is boiling using RR method and then do it with the lid off and more water, there will not be much, if any difference.

You have several fundamental misunderstandings of how phase transitions occur, and if you can't be bothered to look any of this up I think I'm going to have to decline participating in this conversation any longer.

Listen, do you think you are increasing the pressure by covering it with a lid? If so by how much? Is it even 1 PSI? Why wouldn't the tray do the same thing being covered?
The atmosphere outside of a pressure cooker isn't increased when you are pressure cooking, only the pressure within the container is.
There is fundamentally no difference that I can see.

It would be 1 PSI if the lid weighed one pound per square inch.
A tray won't do the same thing when covered because it's not surrounded by moist air which conveys heat much better, and because the partial pressure of water surrounding it is low and any crack or leak in the aluminum will allow gas to billow out.

Is there a difference in the temperature acheived in a substrate in a PC regardless of the container that is within the PC or no container within the pc at all?

I can't believe I just read all that. What's harder to believe is that RR got sucked in by a troll. That's some mighty fine trollin
Just for those who lack exerience and/or may consider the validity of the OP:
Sometimes doing things wrong can actually work. The folks that are arguing against the OP are really trying to establish what's best practice for best chance of success. They are also trying to establish the science behind the best practices.
The appearance of water vapors does not require boiling water and therefore is in no way an indicator of adequate temperatures for sterilizing.
However, boiling water provides steam and steam is enough to sterilize BRF cakes for 90 minutes and whole grains for about 8 hours.
Steam sterilizing in jars locks in most of the moisture because of the equalized pressure and the presents of 100% humidity at boiling temperature.
The heat from the steam transfers to the core of the jars...given enough time.
Because the oven is dry, the water vapor will transfer from the substrate while it's heating. This will result in slower heating of the substrate and simultaneously drying it out.
Given enough time, the end result could possibly be sterile substrate, but likely will be very dry. But, sterility is still unlikely because vermiculite does not transfer heat very well. Vermiculite is sometimes used as an insulter for this reason.
As soon as the substrate begins to cool, the substrate won't be sterile anymore. This is because the only contam barrier is a piece of foil. You will not be able to secure the foil enough to make it an effective contam barrier.
Flours and grains are very rich in nutrition and will contaminate very easily unless kept in a sterile environment. The exception is, of course, when they are completely dry.
If you are actually trying to be successful at growing mushrooms, do not follow the OP's tek.
No matter what you are trying to do in the oven, the result will likely be, at beast, improper hydration. Water baths and steam are the preferred methods of sterilizing and pasteurization because of the control of heat and moisture. Regardless of science and understanding, decades of experimentation have proved this. Ovens suck for mycology purposes.
