Earlier this month, I grew some amazing oyster mushrooms from the Back to the Roots mushroom kit. I harvested some beauties. On the box, it says that you can grow more than one harvest from the box. You can re-soak the entire block, and grow mushrooms from the backside of the kit. Heck yeah, I'll try this again! I soaked the block overnight and forgot about it for a few days. Then yesterday... look what I saw beginning to grow!
