When to determine male outdoors

When will you be able to determine sex in an outdoor enviornment in the northwest of the U.S? Can anyone give me an estimate of how many days after the plant is started, will it show sex? (Non-autoflowering)

Help please

i would say 3 weeks maybe some expert will join in. i wouldnt really worry about it right now it takes awhile for the males to pollinate the females. anybody else have an opinion?

Growing from seed I would venture a guesstimate at about 6 weeks, once the plant starts reach sexual maturity.
