I transferred a ms pastyplate to a few fresh ones, now they all have this dry looking film on top, looks sorta like the agar is dried out (kinda bard to see) but from the side i can see that it's a white film covering the top. What contam is this and what are the causes? The original plate was one of my first pc and still air box runs, just curious where I went wrong.

Bacteria will sometimes make a layer like that quickly covers the surface. If it's in all the ones you transferred the source culture might be contaminated with it. It can be helpful to use antibiotic agar for your spore germination.
