These 2 plants are about 4 weeks old, under 24/0 with CFL´s. I´m pretty sure they´re both male, but I want to be sure.. thanks!
At this stage It is hard to tell if those are pollen sacs or not. Take a topping of the plant, put it in a rock wool cube and put that cutting into flowering and within a week or 2 you will have your answer.
