we use a martha setup and 4 casings got D-slapped by some cobweb mold. the martha is in a closet and it is hooked up to a humidifier. temp/hum were 74/93 at the time of discovery. usings casings w/ 60/40 coir/verm and rye subst. i spray the closet and ourselves with lysol whenever i go into the closet and we also PC our substrate and casing mix. Also, we wear gloves and face mask every time. what are the right steps to take to make sure this doesn't keep happening?
