Rumored to have started in Colorado, I can vouch for it's affinity for the colder weather. Wonderful trich production, naturally high potency. Smells of lemons and gasoline. Easily one of my favorite strains to grow, smoke and dab! Number 4 was my personal baby.
It's been crossed with just about everything at this point. It's a popular strain. Mob Boss comes to mind, it's a sativa dom with chem d as a parent.
