Next round I''ll increase the steam time to 90mins, 24hrs apart...So stay tuned, cause we're gonna nail this thing down...

you inoculate by injecting thru the polyfil right ?

So not usable really..
Any way, the next round of steaming for 90 mins x 2...coming up...
The Rye grass bags are still ok..

normal water amount for cooked rice..
The overcooked rice becomes really mushie and is easily mixed with dry verm...
I figure that actually cooking the rice in water first is likely to kill off most bacteria...
I made some jars also, as a control group...
The bags n' jars were steamed for 150mins..
The blue dots are the innoculation points [1 per bag]..which were then glued shut...
I like the idea of not having to grind the rice then hydrating ,as its all done in one step...
Now we wait...The RGS bags are still OK ,should be germinating any time..

i think i personally would have put a bit less in each bag,
more air, less water and faster to finish
all helps push odds
and these are cheap enough to make a bunch.

Also, the vacuum seal bags are boilable so can handle the heat.
For innoculation you shoot LC right thru the bag and then cover holes with tyvek or in my case a coffee filter (tape the sides down).
I use a roiling boil tho since we are after steralization and not pasteurization.

Also, rolling boil is probably better than just a mild steaming.
Could work. You may want to double bag tho. Water is the worst thing you can get into your substrate.

Pre cooking the rice while hydrating it, is a good prevention method...
The bag which was made with whole "overcooked" rice is looking as good as any,,so if you don't have a grinder - no problemo..
The key ,is to boil the rice or BRF with enough water that it's consistancy is like cream soup ...Then add an equal volume of dry verm .
Make minor adjustments after that, B4 filling bags..
The bags are still strong and supple compared to any oven type bag i've used ..

But, these easily held up to the steam. I didn't have them in the water, instead I used my big pasta-boiling pot with a build in strainer. I just put a few inches of water in (so it was below the strainer bottom), and them steamed the bags for about an hour, three times with 12-16 hours in between each steam.
Three of the bags had popcorn in them, and were about half filled (popcorn was soaked overnight then boiled for about 30 mins prior to bagging). Then in a fourth bag I placed a piece of bread. Initially the bread bag was to just make sure the bags could hold up to the steam, since I didn't want to waste the popcorn. But I continued steaming the bread with the popcorn each time and am now using it as my "control" and so far nothing has grown on either the popcorn or the bread.
One of the bags of popcorn I put a ring of paper-towel tube that I cloned some oyster mushrooms from the grocery on, so it was about 60% covered in mycelium. It's been a couple days since I put the ring in and it looks like the mycelium has begun spreading in to the popcorn, and I don't have any other contams (yet).

As far as PF jars colonizing with out air exchange -i guess they can ,but more slowly..My QT jars never have filters but they're only filled half way, so there's enough air for the whole proccess...

I'd add it if I could.

On the other hand, I found a local hardware store that sells canning supplies, so I can buy some jars. The whole reason I started playing with bags is I was having a hard time finding jars locally - all the grocery stores only carry them seasonally in the fall.

The "Hefty one zip" bags are quite sturdy ,no ruptures so far ,other brands may be less reliable...

and growth stops when air runs out,
as anyone who ever put tape over the pf jar air holes
