...Lion’s Mane is not only easy and fun to grow, but also produces huge delectable fruiting bodies that can be an awesome addition to any meal. As an added bonus- it also boasts some pretty incredible health benefits....
Most mushroom growing is a 2-step process. First you spawn it and wait for it to colonize (take over) the substrate. Then you transfer the colonized substrate to whatever sort of fruiting chamber you're using (which can be a log under the house).
It's not terribly complicated, except that absolute sterility is necessary for the colonizing because the infant fungi have little tolerance for competing fungi, mold or mildew. And it can be done on the cheap. $50 for a very basic set-up (all of which is reusable) and $20 for spores enough to produce several harvests. For that kind of layout productivity won't be the greatest but it still will be well-cheaper than buying from the Piggly-Wiggly.
Plus mushrooms take well to being dehydrated, and some are tastier after rehydration than when fresh. So no matter how large a crop you grow, you can eat them all before they go bad.
