What Are GG4 Auto Seeds?
GG4 Auto seeds are fast-flowering, sativa-dominant autoflower seeds bred from Gorilla Glue #4 and Ruderalis genetics. They deliver 18–24% THC in a compact plant that finishes in 8–10 weeks from seed to harvest, no light schedule changes needed.
Pack Size Guide
| Pack | Best For |
|---|---|
| 1 seed | Single-plant test run or adding one GG4 Auto to an existing tent rotation. |
| 3 seeds | Recommended starting point. Gives you enough to observe phenotype variation and account for any germination hiccups. |
| 5 seeds | Solid choice if you want to fill a small tent or run a side-by-side indoor/outdoor comparison. Our most popular option for GG4 Auto seeds. |
| 10 seeds | Bulk growers and anyone planning successive harvests. Stagger your starts by two weeks and you can pull a fresh crop every month. |
If this is your first time with sativa dominant autoflower seeds, grab 3 or 5. You get room to experiment without overcommitting.

GG4 Auto Seeds: Yield, Growth and Flowering Time
GG4 Auto seeds produce dense, resin-heavy harvests that rival many photoperiod strains — and they do it in roughly half the time. Indoor growers can expect 400–600 g/m², while outdoor plants given full sun regularly push 500–750 g per plant. That output from a plant capping out at around 100 cm is genuinely impressive.
The autoflowering genetics mean the plant shifts into bloom on its own after roughly 3–4 weeks of vegetative growth. No timer adjustments, no stress about light leaks. You run an 18/6 light cycle from day one and let the Ruderalis genetics handle the rest. The entire seed-to-harvest window sits at 8–10 weeks, making these some of the fastest flowering cannabis seeds you can buy.
Standard photoperiod Gorilla Glue #4 stretches past 150 cm, demands a strict 12/12 flip, and takes 12–14 weeks to finish. GG4 Auto stays under 100 cm, flowers on its own clock, and finishes in half the time. If you want the same sticky, potent buds without the extended timeline, the auto version is the obvious pick.
How to Grow GG4 Auto Indoors vs Outdoors
GG4 Auto seeds are the best autoflower for small-space growers who want heavy, resinous yields without managing light schedules or complex training. Whether you have a 60x60 cm tent or a sunny balcony, these genetics adapt.
But here is the honest bit: the 8–10 week sprint leaves zero recovery time for heavy training mistakes. Skip defoliation past week 4. Top only once, and do it early — ideally around the third node, before the plant triggers its automatic flowering phase. If you miss that window, leave it alone. The compact structure handles itself well without intervention.
Indoors, keep your relative humidity at 40–60% during flowering to prevent mould and protect those dense bud sites. Night temperatures around 60–65°F (15–18°C) help bring out the purple hues some phenotypes express. Feed in soil at a pH of 6.0–6.5 and keep nutrients moderate — autos burn easily if you push too hard.
Outdoors, the natural pest and mould resistance of GG4 Auto seeds really shines. The plants adapt well to varied climates and finish fast enough to beat early autumn rains in most of northern Europe. At ~100 cm, they stay below fence lines and blend into a garden without drawing attention.
And the payoff at the end? Curing a jar of GG4 Auto smells like snapping fresh pine needles mixed with overripe citrus and damp forest floor. The buds are dense, sticky, and coated in frosty trichomes. That fruity, piney flavour profile carries through to the smoke — an uplifting cerebral uplifting that gradually settles into a grounding physical relaxation. At 18–24% THC, it hits with real authority.
Growing Steps
- Germination: Soak your GG4 Auto seeds in a glass of room-temperature water for 24–48 hours until taproots emerge. Transfer to damp paper towels if they need a nudge, then move to your growing medium once roots reach 1–2 cm.
- Potting: Plant directly into the final container — 11–15 litre fabric pots work well. Autos dislike transplanting because the root shock eats into their short vegetative window. Use a light, airy soil and avoid hot mixes with slow-release nutrients.
- Light schedule: Set your timer to 18/6 from day one and leave it there. GG4 Auto seeds do not need a 12/12 switch. Flowering kicks in automatically after 3–4 weeks. Keep the lamp 40–50 cm above the canopy and adjust as the plant stretches.
- Feeding: Start with plain water for the first week, then introduce a mild vegetative feed. Switch to bloom nutrients once you see pistils forming. Maintain soil pH at 6.0–6.5 and keep relative humidity between 40–60% during flowering. Flush with plain water for the final 7–10 days before harvest.
- Harvest and curing: Harvest when 70–80% of trichomes turn milky with a few amber heads. Hang-dry whole branches in a dark room at 60°F for 7–10 days, then cure in sealed glass jars, burping daily for the first fortnight. This is where that pine-and-citrus terpene profile really develops.
Frequently Asked Questions
How long does GG4 Auto take from seed to harvest?
8–10 weeks total. Autoflowering genetics trigger flowering by age, not light schedules, so you skip the vegetative-to-flowering switch entirely. Most growers see pistils forming around weeks 3–4, with dense buds ready to chop by week 9.
What is the THC percentage in GG4 Auto?
18–24% THC. It hits hard with a sativa-dominant cerebral lift before settling into a relaxed body calm. The exact percentage varies by phenotype and growing conditions, but even the lower end packs a proper punch.
How much yield can I expect per square metre?
Indoor setups pull 400–600 g/m² under an 18/6 light cycle. Outdoor plants in full sun regularly hit 500–750 g per plant. Proper feeding at pH 6.0–6.5 and steady humidity around 40–60% during flowering will push you toward the higher end.
Does GG4 Auto need a 12/12 light cycle to flower?
No. GG4 Auto seeds flower automatically after 3–4 weeks regardless of light schedule. Run 18 hours on, 6 hours off from day one to save electricity and keep growth steady. There is no benefit to running 24/0 — the plants use that dark period.
Is GG4 Auto good for small grow tents?
Yes. It caps out at around 100 cm, making it ideal for 60x60 or 80x80 cm tents without requiring heavy training or topping. The compact structure and fast flowering time mean you can run multiple cycles per year in a single small space. It is genuinely the best autoflower for growers short on room but not on ambition.
