It will likely take several days, maybe a few weeks. Fermenting conditions can be highly variable, and it's hard to give a single answer to this question. Fermentation time depends on a couple of (main) factors - temperature and salt content.
A day and a half is not likely to produce a finished vegetable pickle unless you ferment it at a very high temperature (above body temperature) with very low salt content, and you inoculate it with something already fermented. Exactly how long it takes is between you and the bacteria. Take a taste every so often and see what they say.
