About Jack
Freedom of Seeds crosses Jack Herer with a ruderalis line to build Jack, a pairing that typically signals an autoflowering or near-autoflowering growth pattern given ruderalis genetics' role in that trait. THC covers a wide swing, from 13 all the way to 23 percent, a broader range than most listings report, which suggests some real variation from plant to plant. The terpene sheet is unusually long, with limonene, pinene, caryophyllene, and humulene leading a list that also includes myrcene, bisabolol, camphene, terpinolene, ocimene, eucalyptol, and linalool — genuine complexity there. Flavor notes come through as sweet, earthy, and fruity, and effects lean toward the upbeat side: happy, euphoric, relaxed, and creative all show up in reports. Nobody has yet logged a flowering time, a grow-difficulty rating, a height, a yield, or a medical use for this cross.
