About Mac N Jack R1
Ethos Genetics crossed MAC 1 with the 1994 cut of Jack Herer to build this hybrid, joining a modern favorite with a genetics icon from the 1990s. It's not an easy plant, rated difficult, and it takes its time finishing, 9 to 11 weeks of flowering before harvest. That patience pays off in potency: THC runs between roughly 20 and 24 percent, real strength backed by two celebrated parent lines. There's no documented flavor or effect breakdown for this particular release, so the draw is squarely the lineage and the numbers, a demanding grow for people specifically chasing what a MAC 1 and Jack Herer cross can deliver at full strength.
