About Grandpas Cookies R1
Grandpas Cookies R1, offered through Ethos Genetics, is one of the leaner fact sheets in the database but no less worth a look. Flowering wraps up in eight to nine weeks, a timeline that keeps it in line with most modern hybrid crosses rather than dragging into a marathon grow. THC tests between 16 and 18 percent, giving it enough strength to satisfy without demanding a tolerance break first. The 'R1' in the name typically marks a specific reversal or release batch in breeder shorthand, though StrainCompass has no further detail on lineage, flavor, or effect for this particular listing. What's documented points to a solid, moderately potent hybrid suited to growers who want predictable timing more than a long list of bells and whistles.
