Gorilla Glue #4 Autoflower

What Is Gorilla Glue #4 Autoflower?

Gorilla Glue #4 Autoflower takes one of cannabis’s most resin-heavy hybrids and gives it a fast, self-flowering timeline. The original Gorilla Glue #4 line built its reputation on extremely sticky, trichome-coated buds and serious potency. Breeders then add ruderalis to that base. The plant moves from seed to harvest on its own clock, with no light-cycle switch required.

Several seed banks sell a version of this cross, each using its own proprietary autoflowering line to stabilise the trait. So growers get that signature heavy, resinous character on a much shorter timeline than the classic photoperiod version demands.

What makes this version stand out is how closely it echoes original Gorilla Glue #4’s reputation for potency and a heavy, euphoric high. As a result, it’s become a popular entry point for growers curious about genuine high-THC character without a full photoperiod season commitment.

Origins & Genetics of Gorilla Glue #4

Gorilla Glue #4 Autoflower generally comes from a Gorilla Glue #4 and ruderalis cross. Two sources instead frame the cross around their own proprietary autoflowering lines. Treat the exact stabilising genetics as varying a little between seed banks.

Most sources also agree on an indica-leaning phenotype, generally putting the split around 55% indica to 45% sativa. THC tells a more mixed story, though. Figures range from 15% up to 26% depending on the source. Treat the headline THC figure as genuinely variable rather than a single fixed number.

This cross has earned a strong reputation across several seed banks for its heavy, resinous character especially. So its core potency stays a genuine drawcard, even where exact percentages vary a little by source.

Gorilla Glue #4 Effects, Aroma & Flavour

Users commonly describe a euphoric onset that eases into a heavy, sedative body feel, alongside a noticeable boost to appetite. That combination makes it a genuine evening option for people after deep relaxation rather than a functional daytime lift.

Meanwhile, the aroma leans earthy and piney, with a diesel edge, a hint of coffee and a touch of sweetness underneath.

Caryophyllene, limonene and myrcene lead the terpene profile in most reports. Our guide to maximising terpenes is a useful companion read if you want to preserve that resinous, diesel-forward character through curing.

Growing Gorilla Glue #4 Seeds

This strain rates as easy to moderately easy to grow for most. One source instead describes it as better suited to an experienced grower given its potency. Since it finishes on its own clock, there’s no light-cycle switch to manage at any stage.

Indoors, its short, sturdy structure suits a Sea of Green setup well. Our guide to growing cannabis indoors in Australia covers the setup basics if you’re planning an indoor run.

Outdoors, this strain handles a range of climates comfortably, and its natural resilience gives it an edge in less-than-ideal conditions too. Our Australian cannabis grow calendar is a useful companion read for timing an outdoor planting correctly.

Gorilla Glue #4 Flowering Time & Yield

Gorilla Glue #4 Autoflower typically finishes its full cycle in 8 to 10 weeks from seed. Two sources instead measure it in days, landing closer to 10 to 11 weeks. Indoors, expect yields of around 500 to 600 g/m² under good conditions. Three independent sources land in that range.

Outdoors, reports genuinely split by a wide margin. One source puts a healthy plant at 500 to 750g, while another reports a considerably lower 230 to 300g instead. Treat that spread as reflecting real variation in growing conditions rather than a single typical result.

Treat those numbers as a solid planning benchmark rather than a guaranteed outcome. Because this strain finishes so quickly, it also suits growers after more than one harvest per season. Our guide to spotting quality weed is a useful companion read once harvest day arrives.

Who Gorilla Glue #4 Seeds Suit Best

This strain suits growers chasing genuine high-THC potency on a fast, low-maintenance timeline. It also suits users after a heavy, relaxing evening effect rather than a functional daytime lift. Specifically, growers comfortable with a stronger strain will appreciate how quickly it finishes.

On the other hand, it’s a less natural fit for anyone after a mild, low-key high or a completely hands-off first grow. If you’d prefer the photoperiod version instead, with a longer veg and a potentially bigger yield, Gorilla Glue Feminised is worth a look. For anyone after a fast, potent grow with genuine Gorilla Glue #4 character, though, Gorilla Glue #4 Autoflower is hard to beat.
