I have these kc45 plants they are 15 or 16 weeks old and aren't showing sex never mind flowering. I just switched from a 200w dual spec cfl on 18/6 to a 300w 2700k cfl on 12/12 a few days ago. Just in case they aren't auto and I got the wrong seeds. Any ideas?
My plants seem to be on a growth spurt after the 12/12 switch so I'm getting more hopeful they were actually photoperiod and will know show sex. If so i think I might have a nice sativas.
