[technique] this might be a wild take but it’s not that hard to grow mushrooms especially now and you don’t really need to be over sterile if you don’t have a bunch of spores wandering your air

like as long as you are waiting till your grains are 100% colonized made sure you used a fresh syringe, iso or alc wipe and inoculate correctly and use non nutritious substrate contam really isn’t much of a problem
