So I've read a bunch on this site and even bought one of Stamet's books. I started with "magic for the masses" which is great. My question is pretty simple. I know brown rice flour(brf) and vermiculite make a great standard for a substrate. I just read the hpoo tek on the "best of" page. Before this hobby, about the only thing I knew about some mushrooms is their affinity for manure. So which is the best way of growing mushrooms when all you're worried about is quality and quantity?
