Take Chem D, the most-used of the 1991 Chem phenotypes, and the one sitting behind Giesel, and put it over 707 OG Kush, 707 OG Kush, the backbone of this catalogue. That is Comet Fuel (Chemdog D x 707 OG Kush). Bred in the Emerald Triangle for the Emerald Triangle, which is a narrower brief than most breeders set themselves.

707 identifies the Chemdog D x 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 Chemdog D x are only the same cross if the number matches too.

Written this way, Chem D is the mother and 707 OG 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 most-used of the 1991 Chem phenotypes, and the one sitting behind Giesel. 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: 707 OG Kush. 707's own worked OG, selected out of the SFV OG line. Parentage: described as a developed SFV OG; the wider OG Kush family is generally traced to Chemdog with a Lemon Thai influence and a Hindu or Pakistani Kush. 707 is the area code covering Humboldt, Mendocino and Trinity. The line was stabilised for Northern California conditions specifically, which is why resin and outdoor finishing matter more in its selection than yield figures do.
• How to read it. Everything below splits into what one parent gives and what the other does. Plants that take from both are the ones to keep.

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 the West Coast OG signature - fuel and lemon from the 707 OG Kush side.
• The Taste. Fuel and earth, greasy and coating, finishing sour up front, turning to lemon over OG fuel, with earth behind it through the exhale.

Where the parents disagree

• Where the nose comes from. One side gives chemical fuel over dark turned earth; the other gives the West Coast OG signature - fuel and lemon. Plants landing in the middle are the keepers.
• Build. On the Chem D side: open and loose rather than compact, wants support once the colas load. On the 707 OG Kush side: balanced indica-sativa, and selected for rugged outdoor production rather than for a tent. Select early rather than trying to train your way out of it.
• Opposite ends. Chem D is reported as alert and head-forward rather than heavy; 707 OG Kush as OG potency, in the Humboldt style rather than the dispensary one. 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. 707 OG Kush is balanced indica-sativa, and selected for rugged outdoor production rather than for a tent.
• Vegetative Phase and Training. Open the middle out early. Light reaching the lower sites is worth more than any late correction.

Effects and Experience

• The Mind. Growers describe Chem D as alert and head-forward rather than heavy.
• The Body. 707 OG Kush is reported as OG potency, in the Humboldt style rather than the dispensary one, and that is the side supplying the weight here.

In the pack

10 regular seeds per pack. Seeds from 707 Seedbank. Most of this catalogue runs through one OG they have selected and re-selected, which is why the crosses share a backbone. Authentic 707 Seedbank genetics.
