this hobby is so much faster than others...just a pain in the a s s over others.

thanks for helping, everyone.

tried the oven bag in large pot technique

after standing around for 1 hour with water at 160 the core is only 120 or so.

FUCK THIS.

Quitting, resting, relaxing, getting more JARS and will never do the oven bag technique again, most likely. Jars are so much easier

It's highly reliable, but a major pain in the ass




WTF is a pain in the ass about it? First, the substrate/casing is heated to 140F, not 160F before the stove is shut off. Second, it's the easiest, least messy way to pasteurize home-grower amounts of substrate or casing material.

One thing that working 12 hour days in my day job, then coming home and trying to grow mushrooms, help out here, and do videos at the same time has taught me, is to use time wisely. I know of no quicker way to accurately maintain a temperature of 140F to 160F for one hour, then the method I teach.
RR





Wait, RR...is it possible to do this using a "rocker" pressure cooker with no gauge? How do you know what temp you're at when using the pressure cooker with no gauge? Do you just do a certain psi (5,10,15) for a certain amount of time? Thank you



I wouldn't pressurize, even at 1 psi it would translate to 212F

Per Paul Stamets (The Mushroom Cultivator) the relatinship of pressure and terperature at constant volume is as follows.
Pressure.....Temperature F.
1............212
3............220
5............228
10...........240
15...........250
20...........259
25...........267

Yeah; as mentioned before, you really want to start out with 130F+ water. Otherwise...you have some wait in store. How much are you pasteurizing at once?

Enough for a monotub at a time (less at a time, unfortunately)
Used probably 5-10 pounds this first time

Just going to do jars. Standing around monitering the core temp and worrying about contams getting into not-so-sealed oven bag just pisses me off and opens up possibilities for error. fed up with the hassle of ovenbags..fuckit

and theres no way i can add 140F water to a half a rubbermaid's worth of hpoo and get it hydrated correctly. I have to add it, mix it, then squeeze it and I aint doin that in 140F temps.

wow you're really making this out to be a lot more difficult than it really is...

while pasteurizing you don thave to be 100% sterile.. or else you would be better off sterilizing... just put it in the pan and forget about it for 2 or 3 hours.. sheesh. you can handle the 90 min wait to pressure cook grains.. but cant go the extra mile to pasteurize bulk? thats retarded. IMO you should just give up the bulk and just case your colonized grains.

- For hydrating with scalding water, I don't wanna deal with it - I'm not going to be having the same texture/structure substrate every time because of differing sources or recipes or differing components (even for the exact same recipe...ex: aged horse manure vs. newer manure is diff. in struc/texture)... etc..so the amount will not be the same for each substrate.

-Since I don't wanna deal with that this first time I was monitoring the core temp (pain in the ass)

If anything, PCing is easier than this bullshit of oven bags in water.

After doing this I've realized jars ARE better, do save time, and don't make you worry about having an open oven bag


I like to do things knowing they work and do em right...I don't wanna second guess on whether or not my core temp reached this or that, or if the outside is partially sterilized. Plus I find jars just easier. To each his own, and fuck ovenbags in pots from now on...sheesh!

Not using hot water was the fuckup - but I can't be dealing with hydrating with hot water, just is way too much of a pain in the ass to me!

Thanks RR.

And thanks everyone else for your persistant help, really appreciate it as always

vacuum bags are pulse friendly and can handle boiling.
