Grow delicious Blue Oyster mushrooms at home with professional results. Most vendors sell small (1 pound) kits, which barely harvest enough for one meal. Our grow kits consist of extra large 5 pound blocks, so you can produce several large flushes, resulting in pounds of mushrooms. This easy Blue Oyster mushroom kit is made with 100% organic and all natural ingredients including oak hardwood, soy hulls, and gypsum. Our Easy Grow Kits allow you to grow your own mushrooms in three easy steps, and come with full instructions. Your mushroom block will be inoculated fresh by a trained mycologist right before it ships. When you receive it, place it in a dark corner or closet where the temp is between 70-85 degrees so it can incubate. Once it is all white and fully colonized (within 2 weeks), cut a 2 inch X or hole in the side of it, and bring it out (no direct light). Lightly mist it with water twice a day. for 10 days, and you will have mushrooms!
