In terms of the effects, phenotype B produces a strong indica-like effect. With that being said, it does not overpower the cerebral sativa-like effects that are characteristic of Jack Herer varieties and phenotypes.
The most obvious phenotypic differences in Jack Herer strains are whether or not they exhibit more indica-like or sativa-like qualities. Beyond that, there are four main phenotypes. They are simply named phenotypes A, B, C and D. The differences can be summarized as follow:
Jack Herer’s phenotype D has a sharp, rich flavour, similar to fresh hashish. It’s generally the pheno with the most obvious physical ‘stone’ effect.
Indoors, this pheno produces most efficiently at a height of 50-100cm.
Due to its complex lineage, Jack Herer has four main phenotypes. Three of them show bold sativa traits, while the remaining indica phenotype, taller and denser, is more of a cash-crop gold mine. Regardless, each phenotype exceeds expectancy, and is a true delight for the discerning grower.

For home growers, this variety might be the most desirable because it produces truly spectacular amounts of resin. Sometimes, the resin content puts pheno-D among some of the most resinous plants we’ve ever seen.
The buds of pheno-A take the form of long strings of inflated, highly resinous calyxes, very much like the Jack Herer pictured in the Sensi catalogue. If potency is the main aim, growers should select this phenotype, which can be reliably identified by its oversized calyxes.
“I kept three extraordinary phenotypes […]. Phenotype #1 has been nicknamed “Fruity Jack” as it’s very fruity, phenotype #2’s nickname is “Spicy Jack”, since it’s spicy. The most potent but least productive is called “Flashback Jack” because its calices are enormous and uber-resinous, and offer the unique, authentic taste of the Jack from coffeeshops back in the ‘90s.” – by Sam89, sensiseeds.com
