Oyster Mushrooms

A few months months ago, I bought grey oyster spawn from Muhroom Mojo to grow in the house. They tasted great. I'd only had oysters a couple times. These  were much better. I decided to propagate them with what I had on hand. I filled a half gallon fruit jar with hard wheat and filled it with boiling water then put a lid on loosely. After the wheat swelled up, I put the jar in the sink upside down to drain th excess water off. After it cooled off I added about 1/3 cup of spawn. Within a week, I could see white mycellium. In another week,it was a third of the way down the jar. I was going to use this to inoculate a bucket of hardwood heating pellets. It's growing so good, I think I'll let it fruit first.

I wonder if I could break the jar?

Anyone have any suggestions for how to increase the spawn? I'm pretty much a beginner, I've grown a couple kids before but no propagation of oysters.

Thanks!

Hi Ken,
I usually use 5 gallon buckets, but there are innumerable methods.

What substrates have you used?

Oysters grow on many substrates. We use sterile grain jars to maintain and transfer spawn. We grow oyster mushroom on straw mostly. Cheap and easy and local. We also like alternating fresh coffee grounds with hydrated cardboard and a high spawn rate in buckets with holes. Some people use hardwood fire pellets. Agricultural waste produce are used worldwide. Oysters grow on almost anything.

I just pruned my apple and pear trees. I used the prunings. I woulnd't normally use apple or pear logs, because they'd be too dense, but chips are often used.  I also put in reeds and pasteurized them in my buckets. They are doing very well.
