using an instapot to sterilize brown rice grain jars
    #27499119 -

So i cooked my brown rice for 10 mins as directed by tek, rinsed, strained it and let it dry on paper towel and let it cool down and put it in jars with a hole in the lid and 2 layers of microfilm over the hole and then put foil over the tops of them, so bam got that part outta the way now my question is can i sterelize these bad boys in this instapot? if so how much water do i put in the cooker and what setting should i put it on and what should i do from here? I also bought some perlite today if thats needed, and waiting for my coco coir to come in the mail

here's a pic of my jars and instapot..ive also made a ghetto spacer for the jars for when i put em in the cooker, i know it looks shot out but hey if it works, it works..any advice from here would be greatly appreciated! this is my first attempt at growing by the way..thanks in advance!

You just copy the link it gives you into a post.



Fwiw the instapot is a gimmicky kitchen gadget not a sterilizer

Fellow nub here. It looks like you're kind of following broke Boi? If so, I'd probably just follow it completely and do the steam sterilization step in a big pot rather than trying to figure out the instapot.

Search for instapot, I know people have used them or atleast talked about them, but I think I remember reading that they don't get to the correct pressures.

Edit: I was curious, so I searched it.  This thread seems to have reputable people talking about using it: https://www.shroomery.org/forums/showflat.php/Number/26520616

Some say to stretch the time out due to lower pressure, some say it does hit 15 psi. 

I don't know man, I'm a direction follower, especially if it's the first time I'm doing something. Variation on a tek is going to make it difficult to troubleshoot.

Thanks,

I don't know any teks that use perlite and coir. I'd be hesitant about any using instapaot and brown rice. But good luck.

I've had nothing but good luck with my Instapot. They're smaller than a straight-up pressure cooker, and they take a little longer to sterilize things, but they work.

I place the metal stand thing in the bottom of my Instapot so the jars don't touch the bottom. Fill about an inch of water, then place the jars inside. Instapots cook at 12psi, not 15psi like a typical pressure cooker, so you are supposed to sterilize for 1.5x the time suggested for pressure cookers. So for grains, people recommend 90 minutes, but in my Instapot I cook for 135 minutes.

First time I ever grew I used BRF for 1/2 pint cakes and did a steam sterilize in a regular cooking pot and it worked

Got a PC after that and moved up to grain

What are you inoculating with?

If you're spawning to bulk you just need the coir, no perlite.

Perlite is used for fruiting Chambers and cakes

Coco coir is used as sub for bulk growing

I've never used an insta pot but sounds like it can work.

I'd try and grab a PC, a small one isn't expensive and should fit at least 6 jars. Maybe can find a new one

Instant pots and knock offs run at 10 or 13 psi. The will work not as good as a canner but if it's that or steam sterilizing the instant pots a better option.

Mine runs 3 hours max and that's what I set it to when I used mine.

If you don't have a proper canner indo highly suggest doing pf cakes though. Running grains is a bit hit or miss and you can start agar and still air box work. Getting good clean cultures and making liquid innoculant, to pf cakes is really Al one needs to have to get a bunch of shrooms

I sterilize rye berries in my Instapot and haven't had a single jar come out contaminated. I don't know why I see people shit on Instapots so much.

I get that a real pressure cooker is better, it gets to 15psi. But as a person living in a small apartment, who does this as a hobby, I don't have the luxury of getting all the best and biggest equipment - and I feel like most users of this forum are probably like me. I use a shitty SAB and an Instapot, and I run grains in glass peanut butter jars with unmodified lids, and I have great results.
