Gorilla Glue #4 Seeds & Genetics

Genetics: Chem's Sister × Sour Dubb × Chocolate Diesel | Breeder: GG Strains | Type: Hybrid (Indica-dominant)

Gorilla Glue #4 was created accidentally by GG Strains through a cross of Chem's Sister, Sour Dubb and Chocolate Diesel. The resulting strain won multiple Cannabis Cups and became one of the most sought-after cultivars globally. Its genetics produce extremely high resin content, often exceeding 25% THC. When sourcing GG4 seeds, look for verified breeders as many mislabelled versions circulate. For growing fundamentals, our beginner cannabis growing guide is the best starting point. GG4 seeds germinate reliably within 3–7 days and transition quickly into vigorous vegetative growth.

Indoor vs Outdoor Growing Gorilla Glue #4

GG4 is a natural indoor performer. Its bushy, compact structure fills a grow tent efficiently. Top at the 4th–5th node and use SCROG netting to create an even canopy — see our SCROG guide for detailed setup. Flip to 12/12 after 4–6 weeks of veg. Outdoors, GG4 reaches impressive size in warm climates. Harvest by mid-October in Northern Europe. Its main outdoor weakness is susceptibility to bud rot in humid conditions — plant in well-ventilated spots. Our outdoor growing guide covers site selection and weatherproofing.

Nutrients & Feeding Schedule for Gorilla Glue #4

GG4 is a moderate-to-heavy feeder with a strong appetite for phosphorus and potassium during flowering. In veg, maintain EC 1.2–1.8 with nitrogen-dominant nutrients. Switch to bloom formula as flowering initiates. CalMag is essential, especially in RO water or coco coir grows. GG4 is prone to magnesium deficiency without supplementation. Our nutrients guide includes specific recommendations for resin-heavy strains like GG4.

Common Problems & Solutions When Growing Gorilla Glue #4

Dense GG4 buds retain moisture and are highly susceptible to bud rot in humid environments. Maintain airflow with oscillating fans and keep RH below 45% in weeks 6–9. Trimming fans around bud sites improves air circulation. GG4 is also known to stretch significantly in the first 2–3 weeks of flowering — manage height with early training. Resin buildup on tools is normal; clean scissors frequently with isopropyl alcohol during trimming.

Harvest, Drying & Curing Gorilla Glue #4

GG4 is best harvested when 70–80% of trichomes are cloudy with 20–30% amber, producing its signature heavy, full-body effect. The extreme resin means trimming is slow work — freeze scissors or use gloves to manage stickiness. Dry in cool, dark conditions for 10–14 days. GG4's complex chocolate-diesel aroma develops fully after 4–6 weeks of curing in glass jars. Burp jars daily for the first two weeks. See our complete harvest and curing guide.

Frequently Asked Questions — Growing Gorilla Glue #4

Why is Gorilla Glue #4 called that?

Gorilla Glue #4 gets its name from the extreme resin production that literally glues scissors and trimming tools together during harvest.

Is GG4 hard to grow?

Gorilla Glue #4 is moderate difficulty. It is a vigorous grower but benefits from training and careful humidity management during flowering.

What yield does GG4 produce?

GG4 is a heavy producer — 500–600g/m² indoors and often over 600g per plant outdoors in optimal conditions.

Does GG4 grow well indoors?

Yes, GG4 excels indoors under LED or HPS lighting. Its bushy structure responds well to topping and SCROG training.

How long does GG4 take to flower?

Gorilla Glue #4 flowers in 8–9 weeks indoors, making it a mid-range flowering strain with excellent yield for the time invested.

Is GG4 resistant to mould?

GG4 has average mould resistance. Its extremely dense buds can trap moisture — keep humidity below 45% during flowering and ensure strong airflow.
