Ban Lipa Yai Shrooms BRF cakes

today i bought 2kg (~4.5lbs) of popcorn kernels

just waiting on the pressure cooker to show up on my doorstep. i had to have it delivered from a different store location

the cooker is going to be useful for everyday life too, though. they are supposed to be handy

i will probably also use it for making cannabutter/oil and every day meals
 
HAHAHA thats so funny.. but im high lol, my set up looked identical last night, 2 bags of popcorn and my case of jars.. how much did you spend on your cooker? i broke down and bought a new one last night at wally world.. 40 dollars 8 quart, what kinda deals you find lol?
 
mine was 60 it fits at least 12 jars in a circle and could be stacked double high from walmart. day 3 of cultivation no sign of anything yet the internet said something about day 5
 
that's hilarious, srh :P

mine's an electric 6qt, it was on sale for $100

sounds like you got a good deal

i just found out that it might take until the end of the week to get here

but i don't want to start without the fucken pressure cooker :P

good luck donmagicjuan

you cant get around it.
 
You can indeed get around using a pressure cooker. You can progressively sterilize your substrate. If you are willing to be fastidious in every other sense, you can boil your substrate, let it sit for 12 to 24 hours and boil it again, some boil it a third time.

it crossed my mind, but now that the pressure cooker is on the way it would feel counter-productive and impatient to get started when it's only a few days away

but if i hadn't bought one, i would have had no problem doing it that way instead

i tried 5 jars that way, read it off the shroomery, all contaminated.. (popcorn tek)... with a pc and popcorn so far.. 0 contaminated out of probably about 10 or so... im trying to learn all the grains and stuff and figure out which is best for me

If you have a PC, then your contamination rate falls drasticly. I don't recall the last time I got contamination in sterilized jars - 90 minutes for jars, 3.5 hours for bags pretty much does everything in.

do the pressure or temperature which you cook at make a difference in the time you need to cook them?

Most pressure cookers are set at 15 lbs. The little weight (or spring) is set to release slightly when the pressure gets more than that so you are limited. Sterilizers (autoclaves) will go higher - and they retain a vaccuum after the fact so that they can be opened in a sterile space after they have cooled. I believe autoclaves can go up to 18 or 20 lbs.

Temperature is always the same - well, sort of - if the pressure is the same - talk to some Boyle's law experts on this I could be way wrong in the theory. Point is though, if that weight is bobbling, you are at about 15 lbs and what ever temperature that corresponds to.

Higher than 230 or 250 and you begin to caramelize your substrate - mushrooms don't like caramel.

Any wet temperature at boiling will eventually kill almost all endospores. But the presumption is that the temperature is wet and everywhere the same, endospores can survive in tiny places in your substrate for quite some time. Now endospores are grown with a tough shell that will resist very high heats for very long periods of time. All it takes is for a single spore to survive in your substrate and you are done. Considering that there may be many thousands or tens of thousands in your jar, even though your heat treatment kills 99.9 percent of them in the first 20 minutes of sterilization, it is those last few resistant ones that you are gunning for.

The best possible trick is to get those endospores to come out of their shells - offer them an ideal environment and let them live just a little while and then your sterilization will work much better. Of course, too long and you will begin to alter the ph of your substrate making it less desireable for your target organism.

I scored one, a 16-quart pressure canner, for $40 off Craigslist. The old man lives to fish and got it last year to can salmon. Didn't say why he stopped or if he bought a bigger one. But Wal Mart sells them for $69 new. Has a variable pressure counterweight marked for for 5-10-15 pounds. Works like a charm. If you buy used check for the obvious like cracks or evidence of a drop onto a hard surface. Make sure the gasket is not checked or cracked. They warp from use but once worked into place they seal if the rubber is good. Make sure the pressure weight is with it and is the same brand.

Take it from a RN - if boiling killed even nearly everything we would do away with autoclaves, autoclave records that indicate time and whether a full cook or flash sterilization. Test strips included in prep packs are there to indicate if we achieved not only time but temp. Heat equals pressure. Pressure cookers allow higher heat by far than boiling for hours at boiling point. Additionally we do not open the sterile pack until just prior to use in a clean (can't be sterile) OR. Then on, we limit handling to the people absolutely necessary with sterile (that is possible) gloves.

Not even enough time and this isn't the place but using the techniques I have learned in medicine I have never had a crop go bad. Knocking on my head with non-sterile work gloves on.

It is a matter of time. Boiling for long enough will kill all but the most thermophilic organisms. Handily, those thermophilic organisms have trouble living in more moderate temperatures. You would not want to do away with autoclaves because they accomplish this sterilization in short order. Now beyond that, you are aware that it takes far longer to sterilize porous materials than glass or steel. Consider substrates as highly porous and thermal resistant. It is always better to use high, wet temperatures in order to sterilize.

As I said however, many will find that even after their pressure cooking times, if they allow their pressure cooker to cool in a highly contaminated room, contaminated air is sucked back into the pressure cooker and may recontaminate the substrate. This does not happen in an autoclave where pressure equalization can be controled.
 
I've been reading everything you guys posted.

I got my pressure cooker yesterday.

got everything started. started soaking my popcorn

went to start pressure cooking and colonizing today.

noticed they sent me the cooker missing 1 valve. can't use it until they send me one.

fuck. =/
 
i had a new thread with an appropriate title for having changed to popcorn tek too

well... when i get that valve and get some new popcorn started i will post that thread and a link to it in here

everything i read and everything you guys post makes me want to not even consider starting without the cooker ready to go.
 
i macgyvered the pressure valve on the cooker to stay closed with some sugru and heavy duty duct tape.

that sounds retarded and dangerous but i wore goggles in my imagination and if you know what sugru is/does then you'll know it wasn't all that dangerous

anyway i incubated the jars and started a journal here
