Extra Large Black Morel Mushroom Garden Spawn Kits Start your own secret Morel mushroom patch outdoors. Once started, it can produce for several years. Our kits will cover up to a 50 square feet area! It's far cheaper to grow your own than to pay over $50lbs a pound! This is the same strain we cultivate commercially on our farm. Detailed instruction are included, as well as our contact information for "tech support"! Up to 500 of our mushroom plug spawn can be added at the time of purchase for no additional shipping cost.
