Chem #1 S1 is the Chem 91 cut selfed onto itself, so both halves of every seed come from that one plant. Chem 91 is the plant the Chem name was built on, known equally as Chem 91 and the SKVA cut, and a self is the only way a clone-only cut like it has ever reached a seed packet. It carries pungent turned earth and diesel with pine and citrus behind it. What you are buying is a look inside one plant rather than a blend of two.
Genetic Lineage
- Mother and Father: Chem 91, selfed. The SKVA cut, the original Chemdog '91 and the clone the whole Chem family is named after. Given as one of thirteen seeds from a bag bought at a Grateful Dead show in 1991. Skunk VA was given a cut in 1995 and has held it since, which is why the line survives.
- What a reversal is for. It puts a clone-only plant into seed without introducing anything foreign. That is preservation work rather than breeding, and it is most of what Humboldt CSI actually do.
- Reading a pack of a self. There is no second parent introducing anything new. Selfing surfaces traits the clone carries quietly, so expect range rather than uniformity, and that spread is the point.
Flavor and Aroma Profile
- The Aroma. Heavy diesel and soil with a thin pine and citrus line at the back.
- The Taste. Greasy and mouth-coating - fuel, then earth and pine, sour at the finish.
Cultivation and Growth Traits
- Plant Structure. A loose, stretchy plant whose branches give way under late weight.
- Before the flip. Decide the shape now. These lines do not tidy themselves up once they are running.
- Flowering Time. Chem 91 runs sixty-three to seventy days. Start checking trichomes a week before you expect to be ready.
Effects and Experience
- The Mind. Growers describe Chem 91 as alert and head-forward, sativa-leaning rather than heavy.
- The Body. Reported in line with that. This is not a plant described as pulling in two directions.
In the pack
7 feminized seeds per pack. Feminized seeds from Humboldt CSI. CSI work from clone stock they have kept for years and reverse it into seed, so what arrives in a pack is the real cut's genetics rather than a seed-line approximation of it. Genuine Humboldt CSI stock.
