Take Chem 91, the plant the Chem name was built on, known equally as Chem 91 and the SKVA cut, and put it over Chem D, the most-used of the 1991 Chem phenotypes, and the one sitting behind Giesel. That is Big Bad Wolf 2.0 (Chem 91 x ChemDog D). 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.

Big Bad Wolf carries a 2 because selections get numbered to stay distinguishable once they leave the room they were made in. It marks this exact mother, and it is the part of the name worth reading closely. 91 identifies the Chem used here. Numbered cuts come out of a population that was grown and sorted, and the number rides with the plant that was kept. Two crosses that both say Chem are only the same cross if the number matches too.

Chem 91 sits on the seed side here, Chem D 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: Chem 91. The SKVA cut - the original Chemdog '91 and the clone the family takes its name from. It traces back to 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.
• Father: Chem D. The workhorse of the Chem family and the cut breeders reach for most. It traces back to another phenotype from the same 1991 seed lot. It is the Chem half of Giesel, and one of the most widely used Chem cuts in American breeding.
• The point of the pairing. Neither parent needed rescuing. Putting them together is about what sits between them, not about fixing either one.

Flavor and Aroma Profile

Neither parent is subtle, and the cross has nowhere quiet to go.

• The Aroma. Heavy diesel and soil with a thin pine and citrus line at the back from the Chem 91 side, against chemical fuel over dark turned earth from the Chem D side.
• The Taste. Greasy and mouth-coating - fuel, then earth and pine, sour at the finish up front, turning to fuel and earth, greasy and coating, finishing sour through the exhale.

Where the parents disagree

• Timing. Chem 91 runs sixty-three to seventy days, and that is the half of this cross you can actually plan around.
• Two noses, one pack. Chem 91 contributes pungent turned earth and diesel with pine and citrus behind it. Chem D contributes chemical fuel over dark turned earth. Which dominates is the main thing that varies.
• Structure varies hard here. Loose and open rather than compact, moderate to heavy stretch, branches that soften under weight late from one parent; open and loose rather than compact, wants support once the colas load from the other. Plan the canopy for the taller outcome.
• They pull differently. Growers put Chem 91 at alert and head-forward, sativa-leaning rather than heavy and Chem D at alert and head-forward rather than heavy. 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. Chem 91 is loose and open rather than compact, moderate to heavy stretch, branches that soften under weight late. Chem D is a sprawler that needs propping once weight goes on the branches.
• 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. 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. Chem D is reported as alert and head-forward rather than heavy, and that is the side supplying the weight here.

In the pack

Feminized seeds from Humboldt CSI. Humboldt CSI are preservationists before they are breeders - most of what they release is a clone somebody has kept alive by hand for years, put into seed so it stops depending on one grower staying in the game. That is what you are buying into here. Real Humboldt CSI stock, not a copy.
