Bugs in fermentation chamber

[Pogopunx82]

I Brewed a four gallon batch of a pale ale to sour. I put it in 4 different 1 gallon glass carboys. One had WL Sour Belgian Mix, one with Brett L, one with a JP starter and one with wild bugs from the grain. Its in my fermentation chamber with 5 other batches of beer. Once those are done in a few days im going to crank up the heat for the bugs. 75-80 degrees. Should I worry of cross-contamination.

not with glass, but all plastic used in the prosecc should be dedicated to sour brewing.

As far as fermenting next to other beers, no need to worry
