My Sativa plants, which went outside on 13 May, and are starting to flower now. They were 6 wks. old at the time. My Indica plants, which were sprouted on the 10th of May, are starting to show signs of flowering. They went outside on 23 July but were under 24/7 lighting until then. I know the Indicas were induced to flower by the introduction of a night cycle but my Sativa strain is about a 7-7&1/2 month plant. The Indicas I raise can be a 6 month plant indoors but this is the first time I have attempted to flower them outdoors.
Light is everything and the days are getting shorter now, about 14 & 1/2 hours in my area.
