and which way is the wind blowing in Uraguay today? LOL. If you plants are happy they should show signs of sex in three to four weeks. These will be preflowers. They won't officially flower until the light changes...ie the days get shorter. This signals the plant that it is going to die and it's time to start reproduction cycles. It can take anywhere from 6-12 weeks after this light change to finish.

Hope that helped.
