Chemdog D x Irene Kush brings Chem D together with Irene Kush. The first is the Chem family's workhorse and the cut most breeders reach for first; the second, Irene OG - a sour-scented southern cut that growers keep for the nose rather than anything else. Two lines that were never going to produce a quiet plant. These are held cuts, not recreations. CSI's entire catalogue works that way, and it is the reason their crosses are worth chasing.

Written this way, Chem D is the mother and Irene Kush the pollen donor. Reversing a cross is not a formality; which plant carries the seed shapes what comes out of the pack.

Genetic Lineage

• Mother: Chem D. The workhorse of the Chem family and the cut breeders reach for most. Its own cross is 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.
• Father: Irene Kush. Also called Irene OG, a sour-scented hybrid out of the American Deep South kept almost entirely for its terpenes. That one comes from traced to an unknown Emerald Triangle plant crossed to Hindu Kush, and widely taken to descend from California OG Kush. CSI recommend a nutrient-rich organic soil with good micronutrient content to bring the terpenes out; it is among the hardest clones they have reversed.
• 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

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

• The Aroma. Solvent and heavy earth, with nothing sweet anywhere in it from the Chem D side, against classic Kush sweetness and pine with an unusual sour diesel edge running through it from the Irene Kush side.
• The Taste. Fuel and earth, greasy and coating, finishing sour up front, turning to sour with a kush base through the exhale.

Where the parents disagree

• The smell is a negotiation. Chemical fuel over dark turned earth on one side against sweet, earthy and floral with rich earth and pine, plus a distinct diesel note that most OG cuts do not have on the other. Neither wins outright in every seedling.
• Structure varies hard here. Open and loose rather than compact, wants support once the colas load from one parent; resilient with a sturdy frame rather than delicate from the other. Plan the canopy for the taller outcome.
• Opposite ends. Chem D is reported as alert and head-forward rather than heavy; Irene Kush as the potent, focused end of the OG family; settling. 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. Chem D is open and loose rather than compact, wants support once the colas load. Irene Kush is resilient with a sturdy frame rather than delicate.
• Training. Worth the effort early - it is the difference between an even canopy and three colas and a lot of leaf.

Effects and Experience

• The Mind. Growers describe Chem D as alert and head-forward rather than heavy.
• The Body. Irene Kush is reported as the potent, focused end of the OG family; settling, and that is the side supplying the weight here.

In the 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. Original Humboldt CSI stock.
