Does water evaporate through the filter patches/polyfill/whatever?

Just wondering about storing PCed grain jars and mycobags before inoculation. I've kept them for quite awhile before and theoretically they should stay sterile as long as anything else canned (that is until the end of the world right?), however might they loose moisture content overtime through natural evaporation? Afaik you can pour water through the patches and it will go through, thus I would assume steam does as well (unless it condenses and falls back into the jars first, I don't know physics well enough to say?). Would the grains naturally hold on to as much moisture as they can and thus it's not a problem? I've noticed as I leave prepped grain jars on a shelf they naturally condensate on the outside so whether this means water is leaving the jars or if it's just cycling around inside them with temperature fluctuations I don't know. Also what about SFD's? Do they allow water through?

You never want the patch to be wet as then contams can grow through it. Also they will dry out water can and will evaporate over time through the patch. Also we pressure cook to make a window for the grain to be colonized by MYC. I could look up some RR quotes for you but basically it's(15psi for 90M) been called "ultra pasteurization" and that sterilization is never complete. That's why extra water leads to contams, the water doesn't spontaneously make bacteria.
This makes me think of a question though and perhaps RR could chime in if he sees this. When is steralization complete. Would something like 60PSI(300+F) for 8hours take care of everything? Aqua regia?

I don't think it's possible for anything ever to be completely sterile as nothing lives in a closed system. Even lab supplies packaged and sealed have *some* pathogens in them and they simply call them 'sterile' and that is the standard by which we go by.

I would imagine there are some truly sterile things on Earth aside from the core of the planet or the upper atmosphere. Perhaps the inner surfaces of the particle accelerators, I would imagine all the radiation+nearly absolute zero would render the surface sterile. Or if you cracked open a piece of cast and forged steel the inner surface would be sterile for some fraction of time.

I feel like everything either comes from the core of the planet or outside from the vacuum of space, thus neither of those case be sterile (where else would we have come from?). Likewise I bet if you looked closely enough at some forged metal you'll find metal eating bacteria or fungi (all metal is is a giant mineral after all). If there is no life there then there is certainly the building blocks of life, and thus life will eventually come from it anyhow. You'd say nothing can survive the heat of a burning star for instance, and yet that is the very place we all came from including, as far as our current theories allow, the entire planet and solar system, our own sun came from another sun even. Where life can grow it will, and I believe that is literally everywhere.

For the purpose of convention and not zen wisdom. I would call the plasma of a star non life. If you want to see it with "don't-know" mind then sure my cell phone is life too. Not everyone is tripping on the 8th level of consciousness. So, for the sake of the argument a virus or prion as a replicating structure that causes changes to it's environment to be successful at creating more of itself. Or something more like that.
