If you have plastic PET bottles, you dont need to worry too much about bottle bombs. So you arent really limited that way, but you dont want them to bubble over when you open them. I would keep them in a refrigerator, otherwise the yeast will probably take away all the residual sweetness and leave you with bottles that gush over like champagne when you open them.
