GG #99

Overview

GG #99 is a name that circulates on some seed retailer and dispensary listings as part of the extended "GG" (Gorilla Glue) family popularized by GG Strains LLC's GG4, aka Original Glue ^[1]. Unlike GG4, which has a documented origin story from breeder Josey Whales and a trademark-driven rebrand history ^[2], GG #99 has no clear, verifiable breeder record in public sources. No data

That matters. In cannabis, a numbered suffix (#4, #5, #99) traditionally means a specific pheno selected from a seed batch by a specific breeder. Without provenance, a "#99" label tells you almost nothing about genetics or consistency.

Chemistry

There is no published chemotype dataset specific to GG #99. Any THC, CBD, or terpene percentages attached to it online come from individual dispensary COAs on single harvests, not aggregated strain-level data.

For context, GG4/Original Glue is generally reported in the high-teens to mid-20s % THC with caryophyllene, limonene, and myrcene as the leading terpenes in most tested samples ^[3]. Weak / limited If GG #99 is genuinely a Glue descendant, a similar terpene profile is plausible — but plausible is not measured.

Also worth noting: strain names are a poor predictor of chemistry. Studies comparing samples sold under the same name across dispensaries find substantial chemical variation ^[4]. Strong evidence

Reported effects

There are no clinical trials on GG #99. There are no clinical trials on GG4 either. Effect descriptions on menus ("heavy body high," "couch-lock," "euphoric") are user self-reports aggregated by review sites, not measurements. Anecdote

What we can say with reasonable confidence: subjective cannabis effects are driven mostly by THC dose, individual tolerance, set and setting, and route of administration, with terpenes and minor cannabinoids playing a smaller and still-debated role ^[5][6]. Strong evidence The popular "indica vs. sativa predicts effects" framing is not supported by chemical data ^[4]. Disputed

So: if GG #99 flower tests high in THC, expect strong THC effects. Beyond that, take specific effect claims with skepticism.

Lineage (disputed)

The GG family's canonical origin is GG4, reportedly a chance cross of Chem's Sister × Sour Dubb × Chocolate Diesel selected by Josey Whales and Lone Watie, later commercialized by GG Strains LLC after a 2017 trademark settlement with the Gorilla Glue Company adhesive brand ^[1][2]. Numbered GG phenos publicly documented by GG Strains include GG4, GG5 (New Glue), and GG#1 (a phenotype from an S1 line) ^[1].

GG #99 is not listed among GG Strains' officially documented releases in public breeder communications the author can verify. No data It may be:

• an unofficial pheno hunt selection by a third-party breeder using GG genetics,
• a marketing rename by a seedbank or grower,
• or unrelated to the original Glue line entirely.

Until a breeder produces documentation, treat the lineage as unverified.

Cultivation basics

Without a verified breeder file for GG #99 specifically, cultivation guidance has to be inferred from the broader Glue family and standard hybrid practice. GG4 is typically grown as a photoperiod plant with ~8–9 week flowering, moderate stretch, dense resinous colas prone to bud rot in high humidity, and a preference for topping/LST to manage its uneven canopy ^[3]. Weak / limited

If you buy seeds or clones labeled GG #99, the responsible move is:

1. Ask the source for the actual breeder and parent lines.
2. Ask for a certificate of analysis if flower is being sold.
3. Assume phenotype variation between seeds is high until you've run it yourself.

See Phenotype hunting for how serious cultivators handle unknown genetics.

Marketing vs. reality

GG #99 is a good case study in a common cannabis pattern: a familiar prefix (GG) plus a novel number (#99) suggests exclusivity and lineage without actually demonstrating either. This is the same mechanism behind "OG" proliferation and endless "Cookies" crosses.

What's real: the Glue family produces genuinely potent, resinous plants, and GG4 is a well-known cultivar with documented history ^[1][2].

What's marketing: any specific effect promise ("great for sleep," "boosts creativity") tied to a specific strain name, and any implication that a numbered suffix guarantees a particular genetic profile. The "indica calms, sativa energizes" shorthand and the "myrcene above 0.5% causes couch-lock" rule of thumb are both folklore, not established science ^[4]. Disputed

Buy on lab results and the specific batch in front of you, not on the name.
