After preparing more agar for our experiment yesterday, there is still nothing questionable growing on any of them, or anything at all for that matter. We left one dish agar exposed to the air, just to see if there was and is any contaminants around that we should be aware of and, from what we can see, there doesn’t seem to be. The sub-cultured Physarum Polycephalum is all doing extremely well at a fairly constant temperature of about 22 degrees.
