A: Stringy buds, large calyxes, and highly potent. This Jack Herer phenotype can grow excessively tall unless flowered when it’s very small.
B: The most indica phenotype of the Jack Herer lineup. This phenotype is compact, a fast grower, and produces a strong yield. This strain has some indica-leaning effects without overpowering the cerebral sativa effects.
C: This one’s similar to phenotype A in many ways, but tends to grow smaller calyxes that look like spikes poking through the buds. Phenotype C produces a heavy coating of resin, which provides the most amount of energy out of the Jack Herer phenotypes.
D: Phenotype D is a good option for home growers due to its high resin production, but may not be right for commercial growers due to the strain’s quick growth spurt during flowering leaving gaps between nodes at the top colas.
