Sour Jack puts Sour Diesel and Jack Herer in one plant, a Karma Genetics cross of a Sour Diesel line with a Jack Herer male, and it smells like both parents at once.
Did you try it?
“It smells like both parents at once.”
Sharp lemon and grapefruit come up first, then the diesel bite, with pine and a faint menthol and herb behind them. On the palate it is lemon soda and fuel, sweet and a little tropical, with toasted pine on the exhale.
The effect lands fast and stays in the head: energetic, clear and busy, good for momentum rather than the couch, and many find it happy and creative, with a peaceful calm running underneath rather than a slump afterwards. Some find it much stronger than expected, it dries the mouth, and a sativa this bright can tip sensitive people toward anxiety.
It is for daytime diesel lovers who want to get things done.

Bud structure
Density varies with the grower and conditions — treat this as a tendency, not a guarantee.
Aroma
Flavour
Sensory data is a curated, hand-mapped seed; detail completeness is medium. Identity confidence is medium. The diagram is this strain's own sensory radar, not a photo. Batch quality still depends on grower, freshness and storage — none of which is captured here.
Sour Jack is typically described with aromas of diesel, citrus and pine and flavours of citrus, diesel, sweet and tropical. Aroma and flavour vary with grower, batch and freshness.
Sour Jack is commonly associated with effects such as energetic, focused, creative and happy. Effects are subjective and depend on dose, setting and the individual — this is sensory guidance, not a guarantee.
Sour Jack is classified as sativa in the SŌMA catalog. These labels are a loose shorthand rather than a precise prediction of effect; the plant's full chemistry and how it was grown matter more.
By sensory profile, the closest strains in the SŌMA catalog include Tangerine Twist, Clementine and Frozen Lemon. SŌMA matches on aroma, flavour and effect rather than name alone.
