North Spore Indoor Spray and Grow Kits have been popular gifts for the past few years. This year we are offering our kits in four different species: Blue Oyster, Pink Oyster, Golden Oyster, and Lion's Mane. We’ve changed the packaging to include descriptive boxes that can easily stack on the floor or on countertops in your store. Suggested retail $25-$30. These kits take approximately two weeks to produce mushrooms.
