Chem Kong 2.0 (Gorilla Glue 4 x ChemDog D) puts Gorilla Glue 4 over Chem D. One is one of the most-copied clones of the last fifteen years and the plant that made sheer resin a selling point; the other is the most-used of the 1991 Chem phenotypes, and the one sitting behind Giesel. Two very different plants, and the point of the cross is what sits between them. What CSI sell is access to their clone collection in seed form. The parents are the cuts themselves, not a line bred to resemble them.

Chem Kong 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. Gorilla Glue carries a 4 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.

Order matters in a cross name. In Chem Kong 2.0 (Gorilla Glue 4 x ChemDog D) the Gorilla Glue 4 side supplied the seed and Chem D the pollen, and the reciprocal - the same two plants the other way round - is a separate breeding decision with its own results.

Genetic Lineage

• Mother: Gorilla Glue 4. One of the most-copied clones of the last fifteen years and the plant that made sheer resin a selling point.
• Father: Chem D. The Chem family's workhorse and the cut most breeders reach for first. 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.
• 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

Expect the profile to move plant to plant rather than settle.

• The Aroma. Heavy chemical and earth with a sour, piney edge from the Gorilla Glue 4 side, against chemical fuel over dark turned earth from the Chem D side.
• The Taste. Thick and coating with chemical-earth weight and sour pine up front, turning to fuel and earth, greasy and coating, finishing sour through the exhale.

What each side brings

• Timing. Gorilla Glue 4 runs around eight to nine weeks, and that is the half of this cross you can actually plan around.
• The smell is a negotiation. Heavy chemical and earth with a sour, piney edge on one side against chemical fuel over dark turned earth on the other. Neither wins outright in every seedling.
• Two frames in one pack. Gorilla Glue 4 is gets tall - a hundred to a hundred and thirty centimetres untrained - and stretches hard through the first two to three weeks; dense chunky colas under a resin coat heavy enough to leave fingers sticky; usually needs extra support. Chem D is open and loose rather than compact, wants support once the colas load. Decide which suits your room before you flip, because you get both.
• Opposite ends. Gorilla Glue 4 is reported as heavy-handed rather than clear; strongly settling; Chem D as alert and head-forward rather than heavy. 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. Gorilla Glue 4 is gets tall - a hundred to a hundred and thirty centimetres untrained - and stretches hard through the first two to three weeks; dense chunky colas under a resin coat heavy enough to leave fingers sticky; usually needs extra support. Chem D is open and loose rather than compact, wants support once the colas load.
• Before the flip. Decide the shape now. These lines do not tidy themselves up once they are running.
• Flowering Time. Gorilla Glue 4 runs around eight to nine weeks. Start checking trichomes a week before you expect to be ready.

Effects and Experience

• The Mind. Growers describe Gorilla Glue 4 as heavy-handed rather than clear; strongly settling.
• 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. Sold as authentic Humboldt CSI.
