Proposition 122 said:

Calling all Instant Potters. How long are you cooking your agar in the Instant Pot? I have the 6-quart pot if that matters. And high pressure I assume?

I do 1 hour and my control plates haven't lead me to believe that my agar is inherently dirty. I make up 1 pint at a time and just keep the jars onhand for later re-constitution. I'm using 8g agar, 8g LME, and 400g water. unmodified lids + foil just like I would with grain prep.

I have about 8 tubs, relatively small, like 6qt. Would the holes not be overkill for it and possibly dry them out a bit. I have an outlet in the closet I could use a fan on a time limit if that would solve the problem.

Not worth it with most shoeboxes ime as they have loose fitted lids that let in plenty of air per volume

Here's how I did my 27qt mini EZ dial tubs:

Could probably do something similar, I used a 1/4" center punch and a pair of vice grips. Can clean the holes up with a razor blade.

it cracks the tub often. on that many holes youre bound to crack at least one. melting is faster with the extra time it takes to be careful.

Yep and that is just not high enough. I did read that the instapot MAX gets 15 psi but I have never personally tested it.

15 or 16 gauge finish nail is about the same size as a coat hanger. They are also more rigid and have a point that might make it easier to press through. Or I guess you could try putting one into a drill like a drill bit and give it a go. It won’t bite like a drill bit and it might heat up by friction. Having not tried it this theory is wild and unproven. YMMV

I'd love to know where the formula you are using came from to check it as a source against USDA or AMA guidelines. No confrontation intended just a need of my own to check math based solutions.

ive only ever had problems with cracking when trying to drill too fast. they key is to go slow and dont apply too much pressure. if cutting larger holes, a fine tooth hole saw works wonders. but whatever floats your boat!

haha thats rad. i guess if you dont have a shit ton of holes to do, no big deal either way. im just imagining how much heating and melting that would have been for my stockpile of totes

youd be surprised how long a screw driver will stay hot for! i can finish a whole tub with one heating. i dont measure. just eyeball and stab. mushrooms dont have eyes. they dont care what it looks like.

More details in my signature although that is specific to grain.

5000 ft altitude, 10.2 psi gauge pressure, absolute pressure = 10.2 + 12.23 (atmospheric) = 22.43 psi, yielding ~115.4°C

At sea level (15 psi gauge, 121°C), no-pour agar plates typically require 20 minutes for sterilization

Thermal Death Kinetics using the z-value of 10°C for Trichoderma, the time adjustment is 20x10^[(121-115.4)/10] = 20*3.63 =72.6

Or you can totally geek out and go to science direct and their thermal death kinetics page

1/16th inch drillbit isnt going to crack plastic. The bigger bits create torque on the material. Dont push. Let the tool do the work.
