We recently purchased a shiitake kit from Fungi Perfecti. I figured it'd be a great way to fuel my mushroom obsession until the fall chanterelle season starts.
The kit is pretty easy to take care of, and we've already had a good fruiting (around half a pound). It should last about 16 weeks and fruit every couple of weeks before it's done fruiting, but I'm planning on getting a few more kits before that. I'm looking forward to a steady supply of mushrooms and transforming a portion of our house into a micro fungi farm!
