Update on the previous post: yes, putting a small piece of wet (white) paper towel in the petri dish does increase humidity and growth rate. In not even 24 hours, one of the four plates I had prepared made a nice connection between the electrodes. The other three slime mold blobs on other plates are either wandering around (bottom center photo)¬†or getting nicely settled on their blobs (bottom left and right photos). That’s a nice speed change from the five days I had to wait for last week!
