Three days in and the mycelium is starting to take off from a spore syringe. I injected bagged grains from another seller, a bag of Uncle Ben's and one of these jars. So far no signs of anything from the other two, but the jar is really starting to take off. I took some pics, but it's really hard to see because of the glare, but there is growth at the top, multiple locations along the side where I injected and a whole lot along the bottom rim of the jar. In just 3 Days!
