Anyone can grow some amazing white button mushrooms at home with this "just add water" countertop kit that comes complete with casing soil and easy to follow directions. You will never eat mushrooms fresher than twisting them from their growing media and cooking them up seconds later! White buttons grow on a composted straw media and fruit when covered with soil (included), so all you need to do is add the soil, water, and watch...It only takes a few weeks for the mushrooms to spring forth and merely days to mature before you are harvesting from your kit! Expect to harvest about 3-4 pounds of mushrooms! Kit measures 16x10x6 inches and comes complete with casing soil and directions, just add water!
