I submitted a review that I made errors in the content. Let me correct the content: it was NOT Midwestgrowkits fault that my shipment was damaged. However, they offered to ship me a replacement of the damaged item. I’ve now inoculated the grain jars that I have and they’re full of mycelium ready to put on my substrate. I’m very pleased with the grain jars. This is my first experience with mushrooms and so far it’s been easy.
