One way to get the oysters to grow after the bag is depleted is to let them drop spores onto pieces of corrugated cardboard. Once the cardboard is nice and dusted by spores you layer them in between straw or some sawdust. Like a cardboard straw sandwich. Then you put a humidity tent over the layers and keep everything humid and around 70 - 80 degrees. Eventually you will see white myceleum growing on the cardboard and they will begin blooming into mushrooms. The hardest part is keeping green mold or other fungi from taking over, fairly difficult.

Does a person need to soak the cardboard before the spores fall on it?
Also can you explain to me how mushrooms survived for years and years out in nature, because some people act like everything needs to be sanitary so we can grow fungi. Wont what people are doing just produce fungi with weak imune systems?
No need to soak cardboard as you will be misting the block of mushrooms that are growing already. Too much moisture can be bad. Fungi only grows in their preferred environment. Otherwise the spores just sit there inert. So the key is to give them their right environment to grow into myceleum. Here's a way to grow mushrooms by soaking the cardboard if you alreasy have a block infused with mycelium
Thanks for the information, here is a video that I found about growing mushrooms:
Please help me understand. What is the substance that the guy is intermingling with the wood chips, and how can I make the stuff? It looks like frosted mini wheat cereal
But I am pretty sure it is mushrooms, so how is it made in nature?
That is mushroom spawn, it's basically an auger that has been sprinkled with spores then blended up and mixed with a substrate. Nutrient auger is a bit tough to keep clean of other fungi. You basically have to work in a really sterile environment to keep other fungi and bacteria out of your auger. Here's a long article roughly explaining how it's done https://sciencing.com/make-nutrient-agar-home-6317533.html
Oyster mushrooms are a pretty aggressive mushroom so you can probably get them to grow without auger.
You can also buy already infused auger and inject it into a substrate to try and get mushrooms to grow. https://www.amazon.com/Root-mushroom-Mushroom-Cultures-erinaceus/dp/B07J2X8SWK/ref=sr_1_6?keywords=mushroom+spawn&qid=1584364378&sr=8-6
Thank you for expaining things to me, I am still trying to figure out ow things work.
I guess since mushroom spawn is generally delicate, that is why mushroom spawn is shipped to customers in a sealed plastic bag. Then my question becomes why are customers instructed to cut the bags open (thus getting rid of the sterile environment?)
Once again thank you for taking the time to teach me about this process.
Once you cut open the bag you mist the openings and the new moisture starts the mycelium producing fruiting bodies aka shrooms. The right temperature and humidity is needed though to get them growing.
Wont the hole introduce too much competition (bacteria and other spores of fungus)that will destroy the mushrooms that you are wanting to grow?
:)
Also how does a person create their own plugs?
Is it easy to identify what you are not suppose to eat?
