Gorilla Glue #4 x Chem 1 sits between Gorilla Glue 4 and Chem 91: one of the most-copied clones of the last fifteen years and the plant that made sheer resin a selling point on one side, the SKVA cut - the original Chemdog '91 and the clone the family takes its name from on the other. Humboldt CSI work almost entirely from clones they hold themselves, so both sides of this are the real thing rather than a seed-line approximation of it.

x Chem carries a 1 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 4 sits on the seed side here, Chem 91 on the pollen side. If you have seen these two names paired the other way round, that is a different pack and not this one.

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 91. The SKVA cut - the original Chemdog '91 and the clone the family takes its name from. It traces back to one of thirteen seeds from a bag bought at a Grateful Dead show in 1991. Skunk VA was given a cut in 1995 and has held it since, which is why the line survives.
• 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. Heavy chemical and earth with a sour, piney edge from the Gorilla Glue 4 side, against pungent turned earth and diesel with pine and citrus sitting behind from the Chem 91 side.
• The Taste. Thick and coating with chemical-earth weight and sour pine up front, turning to fuel first, earth and pine behind it, sour to close, and it coats the mouth through the exhale.

What each side brings

• Two different harvest dates. Around eight to nine weeks for Gorilla Glue 4, sixty-three to seventy days for Chem 91. Judge each plant on trichomes rather than pulling the room together.
• The smell is a negotiation. Heavy chemical and earth with a sour, piney edge on one side against pungent turned earth and diesel with pine and citrus behind it 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 91 is loose and open rather than compact, moderate to heavy stretch, branches that soften under weight late. Decide which suits your room before you flip, because you get both.
• They pull differently. Growers put Gorilla Glue 4 at heavy-handed rather than clear; strongly settling and Chem 91 at alert and head-forward, sativa-leaning rather than heavy. Which end a plant lands on is the main variable.

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 91 is loose and open rather than compact, moderate to heavy stretch, branches that soften under weight late.
• Before the flip. Decide the shape now. These lines do not tidy themselves up once they are running.
• Flowering Time. The parents are not on the same clock. Gorilla Glue 4 runs around eight to nine weeks, Chem 91 sixty-three to seventy days. Judge each plant on trichomes rather than pulling the room together.

Effects and Experience

• The Mind. Growers describe Gorilla Glue 4 as heavy-handed rather than clear; strongly settling.
• The Body. Chem 91 is reported as alert and head-forward, sativa-leaning rather than heavy, and that is the side supplying the weight here.

In the pack

7 feminized seeds per pack. Feminized seeds from Humboldt CSI. Nearly everything CSI put out is built from cuts they hold themselves rather than from other people's seed lines, which is why their catalogue reads like a list of clones instead of a list of brands. Original Humboldt CSI stock.
