I am answering my own question with the suggestions I got in my personal mailbox so at least if you have read the question you know the answer to. I would appreciate if more people would do that...I hate to see all those questions without any answer in the newsgroup.

It seems that it is very important to tape the plates or to cover them with an
adhesive sheet (Prod 15036 from Pierce or sterile Mylar plastic sheets were suggested to me. Just the cover is not enough!  e
This should avoid evaporation in the outer rows, which would increase the glycerol concentration and thus inhibit growth.

Thanks to all that helped me with this problem!
