Fuel Fusion (Chemdog Sis x 707 OG Kush) crosses Chem Sister to 707 OG Kush: Chem Sis - one of the three plants the whole Chem line came from against the 707 house OG - SFV OG worked for Humboldt. Neither is a filler parent, which is why this pairing is worth a pack rather than a look. One worked OG line, many partners. The constant is the fuel-and-lemon spine underneath.

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

Written this way, Chem Sister 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 Sister. Chem Sis - one of the three plants the whole Chem line came from. It came out of the same handful of seeds as Chemdog 91 and Chem D, found in an ounce of Dogbud bought at a Grateful Dead show in Indiana in 1991. Three plants from that batch became the entire Chem family.
• Father: 707 OG Kush. 707 OG Kush, the backbone of this catalogue. 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.
• What to expect across a pack. Two distinct parents means real variation in frame, finish and nose. Select early and take cuttings off anything you would want again.

Flavor and Aroma Profile

The nose is where these two argue hardest.

• The Aroma. The Chem signature - fuel and sour earth, with a sharper, brighter edge than Chem 91 from the Chem Sister side, against the West Coast OG signature - fuel and lemon from the 707 OG Kush side.
• The Taste. Fuel and sour earth up front, turning to lemon over OG fuel, with earth behind it through the exhale.

How the two sides differ

• Where the nose comes from. One side gives the Chem signature - fuel and sour earth, with a sharper, brighter edge than Chem 91; the other gives the West Coast OG signature - fuel and lemon. Plants landing in the middle are the keepers.
• Two frames in one pack. Chem Sister is the Chem family's open, stretchy structure. 707 OG Kush is balanced indica-sativa, and selected for rugged outdoor production rather than for a tent. Decide which suits your room before you flip, because you get both.
• Opposite ends. Chem Sister is reported as clear 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 Sister is the Chem family's open, stretchy structure. 707 OG Kush is balanced indica-sativa, and selected for rugged outdoor production rather than for a tent.
• Veg and stretch. Set the frame while it is cheap to do. Anything you fix after the flip costs you flower sites.

Effects and Experience

• The Mind. Growers describe Chem Sister as clear 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.
