A CLOER LOOK INSIDE…
There is high concentration of Limonene and beta-Caryophyllene both being nearly .40% (.39% to be exact) and this is what is really setting the mood here with Jack White.
The cerebral uplift can be attributed to the Limonene, while the relaxing body high can be attributed to the Caryophyllene.
Ocimene, which is known to modulate or enhance the psychoactive properties of THC is high here at .18%.

CONCLUSION:
Jack White is a Sativa dominant sativa Indica hybrid of two infamous strains, one a lightening rod cerebrally energized sativa capable of maximizing focus, Jack Herer (named after the author) and Indica giant White Widow, who’s potent physically euphoric effects create a solid foundation for the cerebral energy to freely flow.
THE LONG ROAD HOME (…my toke)
Jack Herer is all about focus. The first time I was in 2013 and at that time it was the first time that I had ever had exposure was in about 2014. I immediately fell in love with what I perceived to be a reunion with a strain I already knew. I don’t know for sure, and I never could prove that was the case.
But at the time, the effect was so similar and the nostalgic aroma of pine and lemon and some unknown sour spices almost diesel sent brought back memories of a strain that maybe I had never even had.
Jack White made me nostalgic for a strain that strain again, given the climate of pre-legalized taxonomy may, or may not have been, Jack Herer in the first place…But, from what I recall it is very similar…just a bit more “stoney”.
Another thing is that I never would’ve thought Jack White capable of increasing my appetite to the degree that it does.
But, still even with these Indica traits, Jack White remains predominantly a Herer-like in my opinion.
Jack White by ForwardGro is sort like Jack Herer with a touch of Indica which serves as a physically soothing base for the mind to be propelled into focused action.
I would, and will, most definitely purchase this strain again. It served me well, because the physical high did not sedate me, it just made me feel more relaxed inside and only enhanced the cerebral effects.
