Anything with a THC:CBD ratio of 2:1-1:1.
i.e. - The Killa watt (Skunk#1 x Hindu Kush) cut is a 2:1 and produces a very enjoyable yet functional high.
Thanks EC- I really appreciate it and trust your expertise. Sounds like a winner. I've tried both on their own and could see how combined they would be quite nice. I'm really surprised that the cbd ratio is that high in this combination.
For me, what you're describing is Ace's Pure Purple Haze (20-26 weeks). Ace Purple Haze Thai (14-16 weeks) is a slightly more energetic, faster finishing version of Purple Haze with better output.
If you're looking for saner flowering times, try central american sativas - Honduran, Panamanian, Guatemalan (Tikal) all hit pretty close to what you're looking for. Though Honduran is more stoney / denser than the other two.
Most of the thai leaning lines I've tried are close as well, though thais tend to be more electric and have a slight potential toward nervousness because of the added electric energy. If you're looking for that clear headed experience, I still love CBG Destroyer (a head full of crisp mountain air). Destroyer does tend to be a bit overly energetic, so crossing it to other lines to calm it down may be necessary depending on your personal tastes.
Terpene- I love the description "a head full of crisp mountain air".... In looking at Ace's selection, is the Pure Purple haze from the OT Haze line?
