Pressure Cooker Problem
    #21825874 - 06/18/15 10:21 PM (8 years, 7 months ago)

As a preface, I have attempted to grow mushrooms only once and with the PFtek. I had to abandon the grow after colonization. I also don't easily remember all the steps of the PFtek, (although I think I could remember it with effort). With this being said, I believe that when using the PFtek to grow mushrooms there will be a small contamination.

Pressure cookers have a rubber seal which lies between the lid and the pot. This rubber will be heated and off gas, and then contaminate the substrate. The substrate will have a small amount of rubber (which itself may have pesticides and other chemicals). The mushrooms might (not sure how mushrooms absorb nutrients) absorb these chemicals from the substrate. Therefore the mushrooms will have some impurity.

I believe that any impurity has some physiological therefore psychological effect. It may be imperceptible and in this case likely is. Impurities in psychedelics irritate me because they may alter the effects.

Please comment.

If you're worried about the rubber seal, get an AA. No rubber gasket on an AA:shrug:

Whats an AA?

Gasket eh, good word to know.

I wont be able to grow at home for a couple of years.

It's already kinda hard for me to get shrooms. I have two friends, who are in the same friends circle who I can ask, but this time I'm gonna want to know who grew the shroom's from the person who is selling them and if I can talk to him directly. This seems kinda sketchy I don't even think I should ask about who grew them.

What do you guys think?

Also I remembered that the odd material underneath the cans lids will be a source of contamination as well.

AA stands for All American. They use a metal on metal seal. Furthermore, the small amount of rubber that's in the jars will not "contaminate" your substrate. Toxins in plastic such as bisphenols are not present in canning stuff in a high enough quantity to matter, and said bisphenols certainly won't be absorbed/leached by mushrooms. Contamination refers to competing organisms in your substrate, not deleterious chemicals that may or may not be exuded by heating plastic.

I wouldn't pry into your friend's sources if I were you. If you want to grow discreetly, inoculate 6 PF cakes, and once they're fully colonized, blend them up and mix the slurry into some pasteurized coir/verm inside a clear plastic tote. I will be publishing a stealth grow tek here in the coming weeks, if you're interested.

You can rest assured that this is utter bullshit. :super:

Like I said in the other thread about plastic lids, I work in health foods and deal with this topic all the time at work.

"Were these shrooms grown in a BPA free monotub?" :lol::facepalm::rofldrunk:

They were grown on rye too so they're no good for your bullshit "gluten intolerance" :lmafo:

lol, I refuse to pander to the tinfoil hat fucks any further. I grew up in a time before hand sanitizer and lysol wipes. Back when the playgrounds were all metal and concrete and before anyone even knew what bisphenols were. I grew up in the days when gluten was just the stuff that makes bread dough stretchy and everyone drank tap water. At a year shy of 30 I'm happy and healthy. Just sayin...

Why do you think it is bullshit?

Plastics give off vocs even at room temperature...

I don't think it is unreasonable to think rubber would off gas at the temperatures present in a pressure cooker. And since it will be enclosed with the substrate, the substrate will contain an impurity.

I just want to feel out what other people think about this before backing it up with citations etc... but your guys claims aren't rigorous either. The burden of proof is on me though, so have your fun lol.

What is the humor in this? "Were these shrooms grown in a BPA free monotub?"
It isn't that you think that since shrooms are involved one wouldn't care about impurities is it? If that is the case, keep in mind that shrooms are an incredibly low toxicity substance, and that this is one of the many reasons people love them.

My AA's, of course, have no gasket. But, I believe that the gasket for my Mirro PC is silicone. Pretty inert stuff...

The air that we breath, anywhere on the planet, will give you more toxins, in a day, then all those gaskets, and even monotub liners, will impart to a lifetimes supply of mushrooms. Prioritize your worries. Eat right, exercise, drink alcohol minimally,  don't smoke cigarettes, practice moderation, and all will be good...

It's not unreasonable to think that, but just because you think that doesn't make it true. And if you DO think that, well...that's an exercise in ignorance.

For example, AND why it's bullshit:

At what temperature does rubber "off gas"?

Answer that for me.

I'm not saying that rubber and plastic don't exude volatile organic compounds, but I am saying that the amounts exuded are completely trivial and insignificant.

and I'll go as far as to say that IF 'impurities' are exuded, the mushrooms don't absorb them; rather, they digest them or, and more reasonable, there are no 'impurities' to begin with, and that's why they use rubber in the first place, cause it can handle the pressure cooking process, duh.

Sorry but what you're proposing really is unreasonable :lol: However, if it's any consolation the steam in the pressure cooker doesn't really flow through the inside of the jars anyway. That's why it takes so long to sterilize them. And mushrooms don't absorb toxins from the substrate they break them down, with the exception of heavy metals.
