Oysters are easy, but, I've found that it isn't as easy as they make it out to be. Logs take a lot longer than sawdust... don't even try cardboard. Kits make expensive mushrooms, but, it's a way to get the ones that don't ship well. I've got a friend that set up a clean-room and he's supplying me with innoculant. I have logs going with maitake, lion's mane, and oyster. I'm getting a room ready to put sawdust cultures in. I'll be able to tell you more in a month or two.
