Jack herer is clearly on the C side of Haze.
Having smoked it for years in Amsterdam it is well known as being on the C side , lemon/Pine/Citrus side of Haze , i wasnt the biggest fan of the Jack Herer in Amsterdam at cups etc as to me it was a C5 ( Amsterdam cut) hybrid but with more skunk or another early variety mixed in so much less Hazy than the other Haze cuts that were about , Jack flash to me was a much better Jack herer hybrid that was hit with Haze again i assume as was really nice N Hazy and much more A Haze influence.
People from USA even call it Jack terps , to any strain with the more lemon/Citrus side of Haze and less or no Frankincense.
Also the C5 hybrids throw much more lime green buds and the A side of Haze throws out darker bud and alot more and darker Orange hairs/pistils
Edit
I must be talking about the later version of Jack herer that Johnnychicago mentions as thats the Jack Herer i smoked over the years in Amsterdam.
Jack Flash though wow that had every Haze head at that cup that year loving it , so much more Hazy than any Jack herer I ever tried
