Here are my baby food jars, sorry for the bad resolution. I also did a side experiment with these jars by packing half tight and half loose (
separate thread). They took about 15 days to colonize. You can kinda see the thick white mycelium in a few spots, other than that my resolution is not good enough to see the whispy myceluim covering the rest of the substrate. Plan on moving them to the fruiting chamber today.
