About Chems Sister

New420Guy Seeds traces Chems Sister back to Chemdawg, one of the most influential lineages in modern cannabis breeding, and builds a sativa around it that tests between 15.3 and 18 percent THC. The Chemdawg connection places this plant in the same extended family as OG Kush, Sour Diesel, and countless other fuel-forward hybrids that all share that root genetics. Flowering takes 10 to 11 weeks, a notably long cycle that suggests more sativa-typical growth patterns despite the strain's fuel-lineage pedigree. With relatively modest THC compared to many modern Chemdawg descendants, Chems Sister reads as a more restrained expression of that famous lineage, one that trades extreme potency for the extended, patience-testing flowering period more commonly associated with landrace-influenced sativas.
