Original Glue (GG4S1): the strain that broke potency records
Original Glue (GG4S1) is a feminised cannabis seed from GGStrains that produces one of the most resin-drenched, high-THC cultivars in modern cannabis. This is the official, licensed version of the cultivar formerly known as Gorilla Glue — a strain that swept the High Times Cannabis Cup circuit and became a global benchmark for sticky, potent flower. If you've heard of "Glue" in a grow room, a coffeeshop menu, or a Reddit thread, this is where it came from.
GGStrains built this cultivar by crossing Sour Dubb, Chem Sis, and Chocolate Diesel — a three-way pedigree that produced the genetic split of 63% indica and 37% sativa. The feminised S1 line lets you skip the hunt for a good phenotype and go straight to the one the breeders themselves put their name on.
Why growers keep coming back to GG4S1
Because the trichome coverage is genuinely absurd. Pull a cola off a well-grown Original Glue plant at the right time and your scissors will be glued shut by the end of the first branch — that's literally where the name came from. THC levels reported by GGStrains climb as high as 30%, which puts this in the upper bracket of what modern cannabis genetics can produce.
The terpene profile leans earthy, piney and diesel-sharp, with a chocolate-coffee sweetness on the exhale that hints at the Chocolate Diesel parent. It's not a subtle strain. Grind a bud and the whole room knows.
From a cultivation standpoint, GG4S1 rewards growers who can manage height and humidity. The colas stack big and chunky, and that dense bud structure means airflow matters — especially in the last three weeks of flower when the resin production goes into overdrive.

Growing Original Glue (GG4S1): what to expect
GG4S1 is a medium-to-tall plant indoors with strong lateral branching. Most growers top once or twice and run it in a SCROG or low-stress training setup to keep the canopy even and manage vertical stretch during the first two weeks of flower. Expect a stretch of roughly 50–100% after the flip.
Flowering runs 8–9 weeks. The buds pack on mass late — most of the weight comes in the final 14 days, and that's also when the resin gland density really takes off. Keep night-time humidity below 50% in late flower to avoid bud rot in those chunky colas.
Outdoor growers in northern European climates can bring her home by mid to late October. A greenhouse or polytunnel helps in wetter autumns. She's not the most mould-resistant strain on the market — that's an honest limitation of the dense bud structure — so a sheltered spot or indoor grow suits her better than a rainy Dutch garden.
Indoor grow tips
- Germinate seeds in the method you're comfortable with — paper towel, direct-to-soil, or a peat plug. GGStrains feminised seeds have solid germination rates.
- Veg for 4–6 weeks with topping at the 4th–5th node to build a wide, even canopy.
- Flip to 12/12. Expect significant vertical stretch in weeks 1–2 of flower.
- Support the branches by week 4 — the colas get heavy and the side branches will bend or snap without stakes or netting.
- Maintain RH at 40–50% from week 5 onwards. Good airflow through the canopy is non-negotiable.
- Flush in the last 7–10 days. Harvest when 20–30% of pistils are still white and the trichomes are mostly cloudy with a handful of amber.
- Slow-dry at 18°C and 55–60% RH for 10–14 days, then cure in jars for at least 3 weeks. This strain genuinely improves with a long cure.
Feminised vs autoflower vs regular — which version is this?
GG4S1 is a feminised photoperiod seed. That means every seed you pop will produce a female plant (no male culling needed), and the plants flower on a 12/12 light schedule rather than automatically. If you want the legendary Original Glue genetics without hunting cuts or weeding out males, the S1 is the route GGStrains themselves recommend.
Honest limitations — what GG4S1 isn't
This isn't a beginner strain in the "set it and forget it" sense. The dense colas demand environmental control, and the stretch can catch out growers with low-ceiling tents. If you're running a 1m tall cupboard grow, you'll need to train hard or pick a shorter strain.
It's also not the most forgiving plant when it comes to nutrient overload. GG4S1 prefers a moderate feed schedule — push too much nitrogen in veg or phosphorus in flower and she'll tell you with burnt tips. Feed to the plant, not to the bottle's label.
And despite the 30% THC ceiling, not every phenotype in a feminised pack hits that number. Expression depends on environment, nutrition, and light intensity. A realistic range for a solid indoor grow is 22–27% THC — which is still absurd.
GG4S1 vs other high-THC classics
| Strain | Indica/Sativa | THC | Flowering | Best for |
|---|---|---|---|---|
| Original Glue (GG4S1) | 63/37 | Up to 30% | 8–9 weeks | Resin production, heavy evening smoke |
| Gorilla Glue-style crosses (generic) | Varies | 18–24% | 8–10 weeks | Budget alternative without GGStrains pedigree |
| Classic OG Kush types | 75/25 | 19–25% | 8–9 weeks | Earthy, piney OG terpenes |
We'd pick GG4S1 over a generic "Glue" cross every time if you want the real genetics. The difference shows up in trichome density and terpene expression — it's not marketing fluff.
Complete your setup: Pair GG4S1 seeds with a quality germination kit and a mid-sized grow tent (80x80 or 100x100) to give those stretching colas room to develop. A proper carbon filter is non-optional — this strain is loud during flower, and the diesel-chocolate funk carries.
Frequently Asked Questions
Is GG4S1 the same as the original Gorilla Glue #4?
GG4S1 is the official feminised S1 line bred by GGStrains — the same breeders who created the original GG4 clone. It's as close as a seed version gets to the legendary cut, using self-pollinated genetics from the mother plant itself.
Why did they change the name from Gorilla Glue?
GGStrains settled a trademark dispute with the Gorilla Glue adhesive company and rebranded the line to "Original Glue" and "GG" strain codes. The genetics are identical — only the name changed.
How tall does Original Glue get indoors?
Expect 90–150cm indoors with moderate training. She stretches 50–100% after the 12/12 flip, so a 1.2m tent with topping and netting is the sweet spot. Taller growers can let her run untrained in a bigger space.
Is GG4S1 suitable for beginners?
It's doable for a careful first-time grower, but not the easiest option. The dense buds need good airflow and humidity control, and the stretch catches out growers with small tents. If it's your first grow, consider a more forgiving strain and come back to GG4S1 on round two.
What does Original Glue taste like?
Earthy diesel up front, piney and sharp on the inhale, with a chocolate-coffee sweetness on the exhale from the Chocolate Diesel parent. A long cure pulls out more of the sweet notes and mellows the harsh diesel edge.
How long should I cure the buds?
Minimum 3 weeks in jars after a 10–14 day slow dry. GG4S1 genuinely improves between week 3 and week 8 of cure — the terpenes round out and the smoke gets noticeably smoother. Burp jars daily for the first two weeks.
