Modern Hybrids
Modern Hybrids are cannabis genetics that have been heavily inbred and bottlenecked for THC. I would consider 2000's on, the Era of Modern Hybrid genetics. Though there is no nomenclature for these cultivars, I believe distinction is important as there is a large difference between Modern Hybrid and Landrace genetics that have not been bottlenecked for high THC. Modern Hybrids still are very valuable and there are great cultivars to be found!
