I wanted to try growing mushrooms indoors & the BEST place to get anything mushroom is from Fungi Perfecti (fungi.com) out of Washington. Paul Stamets is the top mycologist in the world & he runs this business. They have prepared kits where all you have to add it water & they also have spores & all the equipment you need for anything. I have tried the kits that came from elsewhere & the ones from FP are so much higher yielding, (they have multiple flushes, plus, if you keep adding freash substrate, you can keep it going). They have several unusual strains of mushrooms in kits to grrow at room temp, plus they have outdoor spawn! They also sell endo & ecto mycorrhizal fungi for any plants you grow & boy does it make a difference in my organic garden!
I really like the Nameko & Pioppinomushroom kits!
