It works! Be patient. In my case, the mushrooms appeared on day 7. Oyster mushrooms, in my opinion, have the best taste, very potent and clean flavor. They are perfect for soups, sauces, and sauté well with other veggies and meats. There’s no earthy taste to them at all. A word of caution, when ready to harvest, collect the entire batch. I made a mistake of cutting three mushrooms only, leaving the rest until the next day. Unfortunately, the bunch dried out completely over night. They were bone dry and hard. When I tried to get them going again by using the back of the package, I had no luck. Overall, a decent product,my it it does need more clear instructions.
