Chemborne 13 (Airborne G13 x Chemdog 91 Bx3) crosses G13 to Chemdog Bx3 — a legendary Afghani indica whose origin story is better known than its pedigree against three generations of Chem 91 worked back into itself. Neither is a filler parent, which is why this pairing is worth a pack rather than a look. That is what makes this catalogue worth carrying - the Chem side is the original plant, kept by hand for thirty years.

Chemborne carries a 13 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. The number in x Chemdog 91 is a specific plant, not a decoration. Lucky Dog Seed Co grow a population out, keep the individuals worth keeping and number them, so x Chemdog 91 is one identified selection rather than x Chemdog in general. A pack naming a different number is a different mother.

Written this way, G13 is the mother and Chemdog Bx3 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 — G13. A legendary Afghani indica whose origin story is better known than its pedigree. Given as broad-leaf Afghani; the botanical evidence points to an Afghani landrace and no cross is documented. The famous story - that it was taken from a US government research programme at the University of Mississippi in the 1970s, one of a batch labelled G1 to G23 - is not supported by any documentation. The federal programme itself was real; a cultivar named G13 inside it has never been evidenced, and most accounts of cannabis history now treat that part as folklore. What is not in dispute is the plant: an Afghani indica selected for resin and potency..
• Father — Chemdog Bx3. The Chemdog Bx3 stud - Chem 91 pushed back into itself three times. Built from a backcross of Chemdog 91 - the cut Skunk VA has held since 1995 - worked back into itself three times. Backcrossing is what you do when you want more of one parent rather than a blend.
• 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 two halves stack rather than blend, which is the whole reason to run it.

• The Aroma. Earthy and sweet with a musky Afghani depth from the G13 side, against the Chem 91 nose concentrated rather than diluted: turned earth and diesel with pine and citrus behind it from the Chemdog Bx3 side.
• The Taste. Earthy hash with a sweet finish up front, turning to greasy and mouth-coating, fuel then earth, sour at the finish through the exhale.

The two halves, side by side

• Timing. G13 runs eight to nine weeks, and that is the half of this cross you can actually plan around.
• Where the nose comes from. One side gives earthy and sweet with a musky Afghani depth; the other gives the Chem 91 nose concentrated rather than diluted: turned earth and diesel with pine and citrus behind it. Plants landing in the middle are the keepers.
• Two frames in one pack. G13 is classic broad-leaf indica structure, short and wide, with very heavy resin production and strong hybrid vigour. Chemdog Bx3 is Chem-family structure, open and stretchy, and it wants support late. Decide which suits your room before you flip, because you get both.
• Opposite ends. G13 is reported as heavy, physical and long-lasting; Chemdog Bx3 as alert and head-forward rather than sedating, as the Chem 91 line runs. 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. G13 is classic broad-leaf indica structure, short and wide, with very heavy resin production and strong hybrid vigour. Chemdog Bx3 is Chem-family structure, open and stretchy, and it wants support late.
• Training. Worth the effort early - it is the difference between an even canopy and three colas and a lot of leaf.
• Flowering Time. G13 runs eight to nine weeks. Start checking trichomes a week before you expect to be ready.

Effects and Experience

• The Mind. Growers describe G13 as heavy, physical and long-lasting.
• The Body. Chemdog Bx3 is reported as alert and head-forward rather than sedating, as the Chem 91 line runs, and that is the side supplying the weight here.
