Diesel Therapy (East Coast Sour Diesel x Chemdog 91 Bx3) is Sour Diesel crossed to Chemdog 91 Bx3. Sour Diesel is the East Coast benchmark for aggressive chemical fuel. Chemdog 91 Bx3 is the Chemdog 91 Bx3 stud - Chem 91 pushed back into itself three times. Between them they cover ground neither reaches alone. Skunk VA has held the Chem 91 cut since 1995, so what sits behind these crosses is the clone rather than a line bred to resemble it.
The number in East Coast Sour Diesel x Chemdog 91 is a specific plant, not a decoration. Lucky Dog Seed Co grow a population out, keep the individuals worth keeping and number them, so East Coast Sour Diesel x Chemdog 91 is one identified selection rather than East Coast Sour Diesel x Chemdog in general. A pack naming a different number is a different mother.
Order matters in a cross name. In Diesel Therapy (East Coast Sour Diesel x Chemdog 91 Bx3) the Sour Diesel side supplied the seed and Chemdog 91 Bx3 the pollen, and the reciprocal - the same two plants the other way round - is a separate breeding decision with its own results.
Genetic Lineage
- Mother: Sour Diesel. The East Coast benchmark for aggressive chemical fuel. Parentage: most likely Chemdog 91 crossed to a Super Skunk in 1990s New York.
- Father: Chemdog 91 Bx3. Three generations of Chem 91 worked back into itself. It traces back to a backcross of Chemdog 91 - the cut Skunk VA has held since 1995 - worked back into itself three times. Backcrossing is what you do when you want more of one parent rather than a blend.
- Why these two. They are not variations on the same idea. They pull in different directions, and that spread is what makes a pack worth hunting through rather than just growing.
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 the Chem 91 nose concentrated rather than diluted: turned earth and diesel with pine and citrus behind it from the Chemdog 91 Bx3 side.
- The Taste. Solvent and sour, greasy up front, turning to greasy and mouth-coating, fuel then earth, sour at the finish through the exhale.
Where the parents disagree
- Timing. Sour Diesel runs ten to eleven weeks, with faster plants nearer sixty-seven days, and that is the half of this cross you can actually plan around.
- The smell is a negotiation. Aggressively chemical and pungent with greasy resin on one side against the Chem 91 nose concentrated rather than diluted: turned earth and diesel with pine and citrus behind it on the other. Neither wins outright in every seedling.
- Structure varies hard here. Tall and lanky with wide internodal spacing, heavy early stretch, rated moderately challenging from one parent; Chem-family structure, open and stretchy, and it wants support late from the other. Plan the canopy for the taller outcome.
- They pull differently. Growers put Sour Diesel at head-forward and energetic and Chemdog 91 Bx3 at alert and head-forward rather than sedating, as the Chem 91 line runs. Which end a plant lands on is the main variable.
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. Chemdog 91 Bx3 is the open, stretchy Chem frame, and it will need propping once the colas fill.
- Training. Worth the effort early - it is the difference between an even canopy and three colas and a lot of leaf.
- Flowering Time. Sour Diesel runs ten to eleven weeks, with faster plants nearer sixty-seven days. Start checking trichomes a week before you expect to be ready.
Effects and Experience
- The Mind. Growers describe Sour Diesel as head-forward and energetic.
- The Body. Chemdog 91 Bx3 is reported as alert and head-forward rather than sedating, as the Chem 91 line runs, and that is the side supplying the weight here.
