Great for mushroom spawn in sterilized containers or bags. You could do small bags in it for hobby growing to inoculate your substrate bags or small buckets. Nothing like fresh gourmet mushrooms in your pan or kept for food stores.Do you calibrate it yearly as that's the only safe way? Who calibrates it for you?
I contacted USDA and they couldn't find a place near me that does calibrations.
I just got a free Pesto .canner on CL. It has gauge, but also a 15psi jiggler. I trust the jiggler, had to spend on a gasket
It compliments my Mirro Matics
