Gorilla Glue #4 (GG4)

Overview

Gorilla Glue #4 — now legally marketed as Original Glue — is a high-THC hybrid bred in the United States by Joesy Whales and Lone Watie, who later formed GG Strains LLC ^[1]. It rose to prominence after sweeping the 2014 High Times Cannabis Cups in Los Angeles and Michigan, and the 2015 World Cannabis Cup in Jamaica ^[2].

The name comes from the strain's extreme resin production: trichomes are dense enough to gum up trimming scissors. Buds are typically chunky, pale green, and frosted with cloudy trichomes; the smell is loud and unmistakable — diesel, sour chocolate, coffee, and pine.

In 2017, the Gorilla Glue Company (the adhesive manufacturer) sued GG Strains for trademark infringement. The case settled, and GG Strains agreed to phase out the 'Gorilla Glue' name by 2020, rebranding the cultivar as Original Glue and the company as GG Strains ^[3].

Lineage (and why it's partly disputed)

GG Strains' official lineage for GG4 is Chem's Sister × Sour Dubb × Chocolate Diesel ^[1]. According to the breeders, GG4 was discovered as a chance pollination — a Chocolate Diesel hermaphrodite pollinated a Sour Dubb plant, and the resulting seeds were grown out; phenotype #4 became GG4 ^[1][4].

A few caveats worth flagging:

• The cultivar is clone-only in its authentic form. Seeds sold as 'GG4' are not the original cut; they are S1s (selfed seeds) or crosses, and the phenotype lottery applies [evidence:practitioner].
• Some early forum accounts gave slightly different parentage orderings, but the Chem's Sister / Sour Dubb / Chocolate Diesel triad is consistent across GG Strains' own statements ^[1][4].
• 'Lineage' in cannabis is rarely DNA-verified. Phylos and similar projects have shown that many named cultivars on the market don't match their claimed pedigrees ^[5]. Treat any strain family tree as a breeder's claim, not a verified record Disputed.

Chemistry: cannabinoids and terpenes

Cannabinoids. GG4 is a THC-dominant Type I cultivar. Lab results from licensed testing facilities commonly report total THC in the 24–28% range, occasionally higher, with negligible CBD (<0.1%) Strong evidence. There is no meaningful CBD, CBG, or THCV expression to speak of in the standard cut.

Terpenes. Reported terpene profiles vary by grower and lab, but published and aggregated lab data generally show β-caryophyllene as the dominant terpene, with myrcene, limonene, and humulene as common secondaries; some pheno expressions show notable α-pinene ^[6] Weak / limited. Total terpene content is moderate-to-high (often 1.5–2.5% by mass), which tracks with the strain's loud smell.

A note on terpene folklore: the popular claim that 'myrcene above 0.5% makes a strain indica/couch-locking' is not supported by controlled human research No data. Terpene levels correlate with smell, not reliably with subjective effect categories.

Reported effects

There are no strain-specific clinical trials of GG4. Everything below is aggregated user report, not evidence Anecdote.

Common descriptions:

• Fast, heavy onset; strong body relaxation
• Euphoric and talkative early, sedating later
• Strong appetite stimulation
• Dry mouth and red eyes (typical for high-THC flower)

Likely overstated or unsupported:

• Specific medical claims (pain, insomnia, PTSD relief) — there is observational and survey-level evidence that high-THC cannabis can reduce self-reported pain or improve sleep onset short-term, but none of it is GG4-specific ^[7] Weak / limited.
• 'Couch-lock' as a guaranteed effect — depends heavily on dose, tolerance, and individual neurochemistry, not the strain name.

Given the THC content, GG4 is not a beginner-friendly strain. Anxiety and paranoia at high doses are well-documented effects of high-THC cannabis generally ^[7] Strong evidence.

Cultivation basics

GG4 has a reputation among growers as vigorous, forgiving, and high-yielding, but with caveats [evidence:practitioner]:

• Flowering time: 8–9 weeks indoors; outdoor harvest in early-to-mid October in the northern hemisphere.
• Structure: Tall, stretchy in early flower (often doubling in height). Topping, mainlining, or ScrOG techniques are commonly used.
• Support: Colas get heavy and dense. Stake or trellis early — branches snap.
• Feeding: Tolerates moderate-to-heavy feeding. Prone to nutrient burn if pushed too hard late in flower.
• Climate: Prefers a drier flower environment; dense buds are susceptible to botrytis (bud rot) in humid conditions.
• Hermaphrodite risk: The original line traces back to a hermaphrodite Chocolate Diesel parent. Stress-induced 'naners' are a known risk in some phenos, especially in S1 seeds [evidence:practitioner].

Authentic GG4 is clone-only. If you want the real cut, source from a verified cutting; if you grow from seed sold as 'GG4,' expect phenotype variation.

Marketing vs. reality

What's real:

• GG4 is a genuinely distinctive, high-THC, resin-heavy cultivar with documented competition wins and a traceable breeder origin ^[1][2].
• The aroma profile and trichome density are not marketing puffery — they're consistent across legitimate cuts.

What's marketing:

• 'GG4' on a dispensary shelf is not necessarily the original GG Strains clone. It may be a seed-grown phenotype, a different cut entirely, or in some cases a different strain relabeled. Genetic verification in the legal market is rare ^[5].
• Specific medical-effect claims attached to GG4 are not based on strain-specific evidence.
• 'Indica-leaning hybrid' as a predictor of effect is folklore. The indica/sativa dichotomy has been repeatedly shown not to predict chemical profile or effect reliably ^[8] Strong evidence.

If you see GG4 marketed as a 'pure indica' or with hyper-specific effect promises, that's the seller talking, not the science.
