Found this spore vendor "Sleeping Forest Fungi", that grows their mushrooms in vitro and prints them in front of a flow hood. So, they say they're sterile and offer a 30day money back guarantee on any print or syringe that's bad. Any one ever buy from sleeping forest fungi? I'm interested because of the sterile procedures they go thru should make clean enough syringes to skip agar and go straight to grain jars. I will be trying them out soon.
