I am culturing acidophilus in petri dishes containing nutrient agar and, even though the plates are incubated upside down, moisture still condenses on the surface of the agar in large drops. These drops move across the surface, spreading the cultures everywhere. Since I am growing cultures in each of the four quadrants of the dish and want to keep them separate, the moisture is causing problems. What am I doing wrong?
