Do-Si-Dos is a hybrid of OG Kush Breath ' a phenotype of GSC (formerly Girl Scout Cookies) ' and Face Off OG from Oregon's Archive Seed Bank. The seed bank is working on an F2 line of Do-Si-Dos phenotypes ' Do-Si-Dos #9, #18, and #22; as well as the unreleased #4 and #13 ' all of which reportedly grow tall and deliver average-sized yields in a 70-day flowering time. The entire F2 line also shows hermaphroditic tendencies inherited from the OGKB parent in approximately 5% of the population, according to the seed bank. Of the three released phenotypes, #9 is described as the most potent, dense and resinous ' producing heavy amounts of dry sift as well as a strong, cookies-and-kush aroma and flavor. Meanwhile, #18 exhibits thick, prominent resin glands and a strong OG Kush aroma, while #22 is a purple, aromatic, grape-flavored phenotype recommended for making ice hash.
