FYI I tried raising the fermentation water to 125F, almost no smell/no yeast, but once I drained the water, massive pin mold in a few days.
A few of the oyster jars I had got green mold, I also tried 1 ganoderma jar with spawn that worked well in normal trays, but it quickly got green mold in the fermented grain jar (even though it was on top).

125 F or even a little higher should be good for a lactic acid fermentation but “no smell” is not a good sign. Lactic acid has a strong sour milk smell and the same fermentation also produces mix of other acids that that don't smell so good. I wouldn't describe the smell of a proper ferment as good but it should be strong smelling.

The fermentation should be lethal to molds as long as the conditions are anaerobic and and none of the floating material is allowed to remain undisturbed on the surface for too long.
The process of draining water from the grain is a likely point where mold spores can enter especially the way I like to do it in open air with little concern for sterility. This is why I pasteurize the grain after it is in the jars. The OP's tek may not work without an in-jar pasteurization after fermentation unless you are working in an extremely clean environment. Also, wild yeasts can thrive in the same anaerobic fermentation that kills surface molds so a pasteurization may also be necessary to kill the yeasts.

I was using a solar cooker to get to 125f so the temp was not sustained at night, perhaps the intense light instead of the heat caused the LAB to die off.

Hi I've been fermenting grain and have reached ph4. Do i rinse the grain or just strain it please?
Have got oyster growing like crazy on fermented straw as well. Great thread.

Just to update what's happening with my fermented grain (WBS).
I didn't rinse the fermented grain, but will do next time as it was a bit sticky.
I'd previously made some oyster cardboard spawn from a jar of sterilised millet spawn. I layered the cardboard spawn at the bottom, in the middle and at the top of the jars, with drained fermented grain inbetween. Some jars were a bit wet so I turned them upside down to drain and took the lid off to remove the water. Obviously sterility isn't an issue, so that was all OK.
The jars really kicked off and most are colonised already, 10 days later. Most look perfectly clean, totally comparable with sterilised grain. All but one look perfectly spawnable.
I'm fermenting some straw to spawn the jars into. I'm excited by how well this is working so far. I'm off grid, so this method of growing without fuel consumption is making a huge difference to how many oysters I can grow.
I'm fermenting using river water. It kicks off more quickly than tap water and is more lively. I may also experiment with delph water. In something I read, probably on this thread, there's a greater variety of fermenting lifeforms in ditch water than river water.
Is anyone else out there fermenting grain?

Does it work for cubensis?
