While most online sources seem to agree that Super Jack was originally bred by Southseeds, some disagree on the exact lineage of this sativa-leaning hybrid. Most tend to fall into one of two prominent camps.

Super Jack was reportedly bred by Amsterdam seed bank Southseeds, which crossed its own Silver Skunk with Jack Herer. Although the origins of Super Jack are up for debate, most online seed banks appear to stock this Jack Herer and Silver Skunk cross.

Other sources claim that Super Jack is a cross of Jack Herer and Super Silver Haze instead of Silver Skunk, a similar, yet slightly different genetic mix than the other version.
