Printing a bottle or vase? Often the best approach is to print in 2 pieces to avoid cupping.

Often to avoid cupping or to allow printing hollow parts, it is necessary to add a perforation to the model. Opt to keep the subtracted part (plug), and join it to the part after washing. 

Leave 1-2mm difference in inner and outer hole radius so the plug will be easier to patch. Use as large of a hole as possible - avoid fluid restrictions which still allow a pressure build up. You can add plugs in NexaX Pro software, or separate a plug in CAD which allows following the part contour.

This video demonstrates best practices for filling plugs.
