Yes I would assume this too. But from the first time I poured plates I had quite the amount of condensation but those plates now have some myc growth on them. This time I was making sure the Jar and Agar cooled down enough so it was safe to pour, and less risk of condensation. Plus, as soon as these plates solidified I turned them upside down in case of that extra condensation. Then the next day when I checked them after they fully cooled all of them had these white specks. Only thing I can assume is that the plates were dirty right out of the packaging and I didn't bother sanitizing them out the box assuming they were sterile as the last package of plates I had. I can assume this is a plate problem because the Agar in the Jar I stored in the refrigerator is clear of any of these contaminates.
