culture starts out as mycelium on agar plates. you use that tissue to inoculate sterilized, hydrated bird seed in mason jars. once the mycelium has colonized the seed you break it up into individual grains again and add that in layers with hydrated sterilized or pasteurized(most common) wheat straw or hay or whatever you are growing the mushrooms on.

once the oyster finishes the hay it will start to form little white knots here and there. you cut out a hole or an "X" over the knots with a razor and spray the holes a couple times a day with water to keep them moist. most of the oysters i've grown indoors will fruit in the open air with no humidity chamber, though they will fruit best if you optimize an environment for them.

one thing i love about mushrooms is that you can clone them fairly easily, so if you happen to get a really nice cluster you can transfer it's tissue onto agar and essentially grow only the mushrooms that are in the cluster over and over again until the culture loses steam. however even if you've ran a clone until it's no longer productive you can start right back from square one by growing out the original, or "master", culture again. you can also clone store bought mushrooms and get pretty decent results for home use
