I have been studying, getting ready to start growing oyster mushrooms. Lots of great info out there but here's where I am stumped. I don't have a basement and I live in Oklahoma where it gets very hot and very cold at times. I am wondering if buying a portable building and controlling the temp would be the way to go or should I get something more like a hoop house that I can keep light out of. Is a wood or metal portable building best or should I just buy an ecosytems with shelves covered in plastic. If I do that I still have to keep the ambient temperature between 60 and 70 degrees outside so I am back to the building question. Would love to know your thoughts.
