I got an oyster mushroom kit (box) from Home Depot a few months ago.
Miracle of miracles, a beginner's luck, grown in basement, it did produce one
very good burst of mushrooms. They made a very good egg omelet too!
Subsequent busts were useless; it is not easy to maintain the right temp/humidity.
It is more fun than just buying mushrooms from the store ...
I will experiment more; next maybe I let nature do its way;
aka.; using dowel plugs (incubation) in short freshly cut hardwood logs?
