Dutch and Spanish breeders built their reputations on stable, uniform lines selected over many generations, while the newer American scene works mostly from clone only cuts and releases crosses fast. That means US packs often carry higher tested THC and more variation, and European packs carry lower peaks with far better consistency. Browsing by breeder origin on https://potentthcseeds.com made that pattern visible across dozens of THC seeds. Neither approach is wrong, they just suit different growers.
