Each kit has 6.5-7lbs of certified organic mushroom mycelium in it, enough to grow 3+ pounds of mushrooms across multiple flushes. Just pull the cardboard circle off the back of the kit, mist it 2-3 times a day and you'll have your own crop of fresh mushrooms in 5-10 days. All kits come with a misting bottle, humidity dome and detailed directions in the top of the box. The Lion's Mane and Oyster kits can be stored in the fridge for up to 6 weeks or at room temperature for up to 2 weeks. The Pink Oyster kit can be stored at 50-55 degrees for up to 6 weeks or at room temperature for up to 2 weeks.
