maybe make a flag. Talk more later. Very serious about this.
Wheat is king. If somebody could take that rafiki gif with him holding up simba to the pride but replace simba with a kernel of wheat, I'd like that haha. All about wheat supremacy
@tedoro- I just use feed grade whole wheat. Not sure of its exact cultivar as it isnt listed on the bag.
As for prep I prep jars as shown in the wheat prep linked in the OP, and for bags I just remove from heat slightly early since bags hold onto a lot of moisture and are more prone to burst grains.
Question 3 is answered in the 2nd post of this thread. I show how I noc up these bags and how I seal using zipties

Ah wheat supremacist.

Not sure what I'm doing wrong besides hitting 17 psi maybe once throughout the cycle.
I usually get two bags that pop, which I hear happen after cutting the stove off.
The remaining 4 have super stretched corners that rip immediately upon shaking, so i'm lucky to get one or two useable bags per cycle.
I can't think of any reasons besides the psi climbing too high during the PC cycle.
Do you think it would be better to have the pressure teeter between 14-15 the entire cycle instead of 15-16?

Did you squeeze as much air as possible out of the bags before loading them? And use jar lids to separate the bags from the sides of the cooker?

Yes.
I spend the most time getting the bags as completely void of air as possible.
Jar lids are between the walls of the PC and in the middle of the two bags as seen in the OP.

My thinking is that people arent dropping their heat after hitting 15psi.
Once your pc hits 15psi, are you dropping the heat on your stove? You should be able to drop the heat down to low after it hits 15psi. If your rocker is jiggling then your heat is too high.
It's the only thing I can think of that is leading to your issues.
I can keep my stove on full blast the entire cook and the jiggler will keep the pc at 15psi but you're heating the walls of the cooker too much. You gotta drop the heat on the stove to as low as possible to maintain 15psi but not so low that pressure drops.
Outside of that, I must live in a void outside of the laws of physics cause I get maybe 1 popped bag in a year of cycles.

I use unicorn 3t standard. Ive used their thick bags also but I dont have any issues with the standard ones. All the bags from the op are standard 3t 8.5x5x19

I use the unicorn 3T bags as well.
I find my gas range to be extremely tricky to dial in. I can never get it to sit right at 15. It's usually between 16-17 or it's just dropping below 15 the entire cycle.
I find myself adjusting it (micro adjustments, hardly noticeable) every 5-10 minutes for the entire 3.5 hr cycle.
I have three quarters taped to the rocker weight, going to try 2 and see if that makes any difference in helping it stay at 15 psi.

What is the weight rated without the quarters?

It's the standard presto 23qt regulator weight, rated for 15psi I believe.

I’ve had a bunch of bags expand into weird shapes from the jars or lids around them, but hasn’t been a problem so far.
It’s weird though cuz then some bags come out perfectly fine. Probably related to heat and how much air is in the bag like you said.

Its crazy they expand and pop as unsealed bags. I've gotten that when I preseal.
I agree, if steam is escaping the bobble, then the contents are boiling. If steam is escaping at the end of the cycle, the bags are completely up to temp and could boil within.

if the bags are popping after the heat goes off as mentioned up-thread, I'd suspect boiling on cool-down. Basically, the vapour space in the PC (around the bags) will cool and condense faster than the bags themselves, which lowers the pressure. But if the bags are still plenty hot inside, they will now be above their boiling point at that pressure, and could generate some steam.
Next time try lowering the pressure/temperature slowly- like turn off the heat for 10 mins, then put it back on low for 5 (or whatever is needed to pause the pressure decrease), and repeat for a little while.

I've also noted that upon ending the PC cycle, if there are any leaks... the pressure drops too fast and the description above (hot bags boiling) happens. My Prestos are sometimes weeping a tad in the gasket. I then kick the burner on low and ease it down to zero over a 30-40 time period.

I forgot to ask before, do you normally end up with the top of the grain uncolonized?
All four of mine have a bare layer on top like when I had too much gas exchange on my jar lids. I’m sure it’s not a problem since filthy did that whole tub with bare looking grains but if there’s a way to fix it I’d prefer that.
I was thinking maybe mp tape over half the filter or rolling the bag a little more so some of the filter is covered up.

Ya it happens often with bags. It's not a huge issue usually. Best way to avoid it is to make sure youre using .2micron bags and not .5 for grains, and to really dial in your grain prep for bags.
It's a fine line between perfect and over hydrated which leads to lots of popped grains. Popped grains arent all bad in bags since you dont have to shake but starchyness can lead to slow growth
