You guys have the best products I’ve never had any issues with contamination. Everything comes sterile and ready for whatever spores u want to use. The casing mix is the best quality u can buy. Plus ur customer service is outstanding. Also fast shipping so everything comes fresh n ready to use. If u do have any issues ur fast to make things rite. Honestly the only issue I’ve had was grain bags but they were fast to make it rite and sent me a new one. The grain jars are the way to go tho. I’ve had better results with the grain jars then grain bags. Also the jars to have cakes work great if ur not into doing the bulk route. I always recommend Midwest grow kits to any beginner or experienced mushie growers. You can’t go wrong with these guys.
