Maybe it is just an artifact of the photo, but it looks like contamination to me. You might get away with using the top part of the jar for spawning a mass substrate like straw, but I would not use it to make more grain jars.

1. If you get a failure and have to toss a moldy mess into the compost, will it break your heart?
2. What are you inoculating the wheat with? If it's one of our more unique mushrooms that don't tend to have toxic copycats, then it should hopefully be quite obvious whether or not you got what you expected. A friend gave me a Lion's Mane kit and it is very different from what I usually see locally, as an example.
There are places that have thrift shops with pressure cookers. However, often with second hand, there may be gaskets that need replacing (that's a regular thing with my large cooker, but less an issue with my new small one). Most of the gaskets are available online if local shops don't carry them.
