AJ Sour Diesel x Lemon tree sits between Sour Diesel and Lemon Tree: the East Coast benchmark for aggressive chemical fuel on one side, a Santa Cruz cross of Lemon Skunk and Sour Diesel, and the benchmark most lemon lines answer to on the other. Both parents here are cuts CSI keep in their own room. That is the whole difference between this and a seed line named after the same strains.

Sour Diesel sits on the seed side here, Lemon Tree on the pollen side. If you have seen these two names paired the other way round, that is a different pack and not this one.

Genetic Lineage

• Mother: Sour Diesel. The East Coast benchmark for aggressive chemical fuel. Given as most likely Chemdog 91 crossed to a Super Skunk in 1990s New York.
• Father: Lemon Tree. A Santa Cruz cross of Lemon Skunk and Sour Diesel, and the benchmark most lemon lines answer to. Given as Lemon Skunk x Sour Diesel.
• What to expect across a pack. Two distinct parents means real variation in frame, finish and nose. Select early and take cuttings off anything you would want again.

Flavor and Aroma Profile

Two distinct smells, and a pack will give you both plus everything between.

• The Aroma. Aggressively chemical and pungent with greasy resin from the Sour Diesel side, against bright citrus with diesel weight holding it down from the Lemon Tree side.
• The Taste. Solvent and sour, greasy up front, turning to zesty and sour turning heavier and more diesel-driven through the exhale.

How the two sides differ

• Timing splits the pack. One parent wants ten to eleven weeks, with faster plants nearer sixty-seven days, the other eight to ten weeks. Expect the fast plants down well before the slow ones are ready.
• Two noses, one pack. Sour Diesel contributes aggressively chemical and pungent with greasy resin. Lemon Tree contributes sharp lemon and citrus over a fuel base. Which dominates is the main thing that varies.
• Two frames in one pack. Sour Diesel is tall and lanky with wide internodal spacing, heavy early stretch, rated moderately challenging. Lemon Tree is medium height, around ninety to a hundred centimetres indoors. Decide which suits your room before you flip, because you get both.
• Opposite ends. Sour Diesel is reported as head-forward and energetic; Lemon Tree as bright and uplifting rather than heavy. The cross sits somewhere between and moves plant to plant.

Cultivation and Growth Traits

• Plant Structure. The two parents disagree here, so plan for range. Sour Diesel is tall and lanky with wide internodal spacing, heavy early stretch, rated moderately challenging. Lemon Tree is medium height, around ninety to a hundred centimetres indoors.
• Vegetative Phase and Stretch. Shape the plant before the flip. Correcting a frame in week six is harder work than setting it in week two.
• Flowering Time. The parents are not on the same clock. Sour Diesel runs ten to eleven weeks, with faster plants nearer sixty-seven days, Lemon Tree eight to ten weeks. Judge each plant on trichomes rather than pulling the room together.

Effects and Experience

• The Mind. Growers describe Sour Diesel as head-forward and energetic.
• The Body. Lemon Tree is reported as bright and uplifting rather than heavy, and that is the side supplying the weight here.

In the pack

Feminized seeds from Humboldt CSI. What they sell is preservation work: old clones reversed into seed so the line survives past whoever is currently keeping it alive. Original Humboldt CSI stock.
