It depends on the strain, and when you put them into flower (12/12 lighting). Say somewhere from 4 - 8 weeks, possibly longer.

takes as long as it takes

If you use an addative such as bud blood when you put a plant into flower, a plant will show sex much much quicker. I have found when using bud blood, on any strain, that the sex shows within 3 days every time. Otherwise without an addative it usually takes between 7 to 21 days.

My stats:
Soil grow
250w HPS

Usually takes about 3-5 days once I switch them to 12/12.
