Every tank is different, not unlike a snowflake. I, personally, experienced one that took about 2 months. Everything I used was brand new, and had no bio-life on it, so mine took a little longer. I simply used a couple of damsels, a mistake I later learned, and boy did I have a mess. Algal blooms, cyano, hair algae, everything you could imagine. I would say using LR and LS, your cycle should take about a month, but that's a shot in the dark. It could be anywhere from a week, to months.
