Gorilla Glue #4 Auto by Seeds66 brings the Glue character into a much shorter automatic run. This line combines the resin potential and intensity of the original GG4 with our own Seeds66 Ruderalis, resulting in compact, robust plants whose flowering phase takes about 55–65 days. If you want the classic Gorilla Glue impression without committing to a long photoperiod grow, this autoflower version is a very straightforward option.

Origin & Seeds66 selection
Gorilla Glue #4 Auto by Seeds66 is based on a cross between a stable GG4 cut and our in-house Ruderalis line. The aim was an autoflower that stays recognisably close to the feminized Gorilla Glue: high resin levels, a strong hybrid effect and a flavour profile that clearly points back to the Glue family, while keeping the structure compact and the flowering window shorter.
During selection we focused on phenotypes that combined three points: reliable automatic flowering, useful side branching and a dense resin layer suitable for dried flowers as well as extracts. Only lines that showed this behaviour repeatedly in our California documentation were released as Gorilla Glue #4 Auto.
Growth & cultivation
Gorilla Glue #4 Auto grows compact to medium in height and fits well into grow tents and discreet setups. Indoors it usually reaches 40–110 cm, depending on pot size, light intensity and medium. A light, airy substrate and enough root space help keep growth steady. Gentle positioning of the side branches opens up the canopy without putting the plant under unnecessary stress.
From around week three the shift into flowering becomes obvious, with no need to change the light schedule. A constant 18/6 or 20/4 rhythm has worked well in many grows. The flowering phase itself takes about 55–65 days; the total time from seed to harvest depends on how long you let the plants develop before flowering really sets in. Outdoors, Gorilla Glue #4 Auto can reach 70–150 cm and produce solid yields in sunny spots, even where the season is relatively short.
Seeds66 tip:
Start Gorilla Glue #4 Auto directly in its final pot and keep stress low from week three onwards. A well-aerated medium, consistent watering and moderate nutrients usually lead to better results than pushing everything to the limit. Under good light and stable conditions, the plants develop compact, sticky flowers with a clear Glue identity.
Aroma & terpenes
While drying and curing, Gorilla Glue #4 Auto builds a dense, multi-layered aroma. Many phenotypes combine a sweet, fruity note reminiscent of pineapple or mixed fruit with an earthy background. Depending on the run, a light diesel tone appears that links the profile to the photoperiod GG4 line.
The terpene combinations often include myrcene, limonene and pinene. Together they create a profile that fits well into the Glue spectrum: spicy depth, a fresh citrus edge and a noticeable fruit component, especially after a slow dry and patient cure. In the smoke or vapour it tends to leave a mix of citrus, wood and a hint of diesel.
Effect
With a THC content of around 20–24%, Gorilla Glue #4 Auto belongs to the stronger autoflower lines in the Seeds66 range. Many users describe a fast head effect at the beginning: thoughts quiet down, everyday pressure feels more distant and attention shifts towards the moment.
As the effect continues, body relaxation becomes more pronounced. Muscles loosen up, the overall pace slows and calm activities like films, music or quiet conversations often feel like a natural fit. Compared to the feminized Gorilla Glue #4, the impact is slightly more moderate but still clearly on the upper end for an autoflower.
Seeds66 stance
For us, Gorilla Glue #4 Auto is an everyday strain with a bit of ambition: easy enough to give new growers a fair chance, but direct enough in its reaction to light, water and nutrients to show how clean a setup really runs. This kind of line fits Seeds66 because it allows learning while still rewarding careful work.
Our principle behind it is straightforward: a strain remains in the catalogue only if it proves itself in practical cultivation and keeps its character over multiple runs.

Frequently asked questions about this strain
1. Is Gorilla Glue #4 Auto suitable for beginners?
Yes. The line is fully feminized and autoflowering and tolerates many typical beginner mistakes as long as it is not constantly overwatered or overfed. It is a good entry point for growers who want to try a more potent autoflower.
2. How long does Gorilla Glue #4 Auto usually need from seed to harvest?
The flowering phase is around 55–65 days in most setups. The total time from germination depends on how long the plants are allowed to build up before flowering and how stable climate and light remain.
3. What yields are realistic?
Indoors, 450–550 g/m² are achievable under strong light and steady conditions. Outdoors, yield depends heavily on sunlight, pot size and soil; 60–200 g per plant is a realistic range.
4. What light schedule works best?
Many growers run Gorilla Glue #4 Auto on 18/6 or 20/4 from start to finish. A constant schedule is more important than the exact ratio, as frequent changes tend to unsettle autoflowers.
5. How strong is the smell during flowering?
From mid-flower onwards the aroma becomes clearly noticeable: fruity notes, citrus, earth and a light diesel tone. Indoors, a properly sized carbon filter is strongly recommended.
6. Which Gorilla Glue variants does Seeds66 offer?
Besides the autoflower version, Seeds66 also offers the Gorilla Glue #4 feminized and the CBD Gorilla Glue Fast Version.
