Why so much condensation? (now pinning!)

I decided to give grow bags a go. I made an inoculation port with RTV over that that micropore tape. (It popped off after inoculation but I put a fresh piece of tape over it)
It cooled for a good 8 hours but there's a fuck ton of condensation.
How do I avoid this in the future? It had to have come thru the filter patch, as I heat sealed the end shut.
I'm pretty sure the water content was fine because it passed the paper towel test prior to loading.
I also made sure the filter patch was on top and the bag was in the center of the PC.

Paper towel? I think you were supposed to use tissue paper.

Your grain was too wet. Dont get it so hydrated next time. You can get by having the grain a little wet in smaller bag or jar sizes. When you got 4 or 5 quarts of grain in one container its very easy to get it too wet.
Also in a bag all the moisture will go to one spot in the bag when sterilizing. Usually you can just shake it around and redistribute it

Great, thank you for the advice!
It seems it wasn't all the way cooled before I knocked it up. It wasn't hot but definitely warmer than the environment that I inoculated it in. The condensation has cleared up a bit; I'll keep an eye on it though.
I have a bag of pure millet that I've been neglecting to use; I found a good tek here I might experiment with.
Out of curiousity, do you prefer bags or jars? I've lost a few jars recently to green mold, the only variable is using injection ports and not putting RTV around the top of my SFD, so I decided to dabble in bags. I gotta admit, I do love the arts and crafts aspect of making jars. I think I'm going to switch to plastic lids, though.

Also I figured why not make the most out of them and add these injection ports? When it's dry I'm gonna do the other side too.

It's not actually looking as bad as it did. I'll keep a tight eye on it for contams but it was definitely the temperature differential that caused the initial spike.

After breaking it up the other day. Seems to still be good. A little slow because we're waiting until the last minute to turn the heat on, but in digging the inoculation points.

Still going strong, no signs of contams. Hopefully another week. I'm gonna case it with verm/peat/lime. I haven't done a casing in a decade so I'm curious to see how it performs.

Yea I have been doing 24 hour soak on wbs but I am going to lower it to 12 hours, hopefully it will help with the condensation and burst grain issues

I would just spawn it to straight coir. In a mono

Only coir? I've always done coir/verm but this time I decided I'd like to try a casing layer as well. What would be the benefit of straight coir? Doesn't verm help it hold moisture better?

I recently stopped using verm and it actually seems to be growing better. I only use casing layer on PE variety

Yeah these are APEs. My LC is producing some crazy potent ones (as expected) but I'm hoping for a more even pinset. I've only started growing again in the last year but I've never had a nice, even, full pinset.

I believe that condensation might have happened because you sealed it before PCing it
Once you turn off the burner on your stove, it will stop applying heat (duh hehe) to the bottom of the PC which will cause the steam molecules to lose kinetic energy to their environment (the walls of the PC and walls of whatever you are PCing) and thus a decrease in pressure
As the pressure drops, the boiling point of water also drops (inside whatever you are PCing, in this case the grain bag) so that whatever excess water was inside the bag from the start will boil off from the surface. As the bag itself begins to cool its temp will "catch up" to the lowered boiling point (or condensing point now) and the water that boiled off will start to turn back into liquid, and some of that liquid will end up on the bag walls
Basically, it came mostly from the water on the surface of the grains. I know you said it passed the towel test, and I'm sure it did, but it's impossible to remove ALL water, even on the molecular level, from grains by air drying. If you leave the bag open (folded, but not sealed) then some of the moisture would evaporate out of the bag as it cooled
At least that's how I think it works. Physics is hard
