🌱 How to Grow Gorilla Glue #4 Indoors (Josey Wales Cut Grow Guide)

Gorilla Glue #4, also known as GG4 or Original Glue, is one of the most legendary modern cannabis cultivars ever released.

Originally selected by breeder Joesy Whales, GG4 became world famous for its extreme resin production, loud diesel-forward terpene profile, and heavy-hitting hybrid effects.

This cultivar earned multiple major cannabis awards and helped define the resin-heavy era of modern cannabis cultivation. The “glue” name itself comes from how sticky the resin becomes during trimming.

For growers chasing frost, loud terps, and classic elite genetics, GG4 remains one of the most respected clone-only cultivars ever released.

🧬 GG4 Genetics & Growth Style

GG4 was originally created from:

• Chem Sis
• Sour Dubb
• Chocolate Diesel

The plant typically grows with:

• medium-to-tall structure
• strong lateral branching
• moderate node spacing
• vigorous canopy development

GG4 tends to stretch significantly during early flower and responds very well to canopy training techniques.

Its branch structure is strong early on, but heavy flower production later in bloom usually requires support.

💧 Drinking and Feeding Behavior

GG4 is generally considered a medium-to-heavy feeder.

It:

• responds well to balanced feeding schedules
• tolerates moderate-to-higher EC levels
• benefits from calcium and magnesium support in many environments

While the cultivar can handle aggressive growth, many growers report that GG4 performs best under balanced nutrient input rather than excessive feeding strategies.

Healthy root zone management is especially important for maximizing resin production.

💡 Lighting and Environmental Response

GG4 performs extremely well indoors under high-intensity lighting.

It:

• handles high PPFD well
• responds positively to stable environmental control
• thrives in balanced temperature and humidity ranges

Humidity management becomes increasingly important late in flower due to dense bud development and heavy resin production.

Many growers lower humidity during late flower to:

• improve resin preservation
• reduce mold risk
• maintain terpene quality

The cultivar is also known for producing extremely strong aroma throughout flower, making proper odor control important in indoor environments.

✂️ Best Training Style for GG4

GG4 responds extremely well to structured canopy management.

Recommended training methods include:

• topping during veg
• low stress training (LST)
• trellis support
• lollipopping lower growth
• moderate-to-heavy defoliation

Because of its vigorous branching and late flower weight, trellis support is highly recommended.

Without support, heavy branches may lean or collapse late in bloom due to resin-heavy flower development.

🌼 Flowering Behavior

GG4 typically flowers within:

• approximately 8–10 weeks indoors

Key flowering traits include:

• aggressive resin production
• dense trichome coverage
• strong stacking
• moderate-to-heavy stretch
• dense but slightly spongey flowers

The flowers are famously sticky and heavily coated in resin.

Many growers describe GG4 as:
👉 “more trichomes than plant”

Yield potential is considered moderate-to-high depending on canopy management and environmental control.

🔥 Terpenes, Flavor, and Effects

GG4 is famous for its loud, layered terpene profile.

Growers can expect aromas including:

• diesel
• earthy funk
• pine
• citrus
• chocolate undertones

The flavor often carries:

• sour fuel
• earthy sweetness
• chemical funk
• subtle chocolate notes on certain phenotypes or longer flower times

Resin production is among the highest in cannabis history and remains one of the defining characteristics of the cultivar.

Effects are commonly described as:

• euphoric
• relaxing
• mentally uplifting
• physically heavy over time

GG4 remains a favorite among both flower and hash producers because of its terpene intensity and resin output.

🧠 Why Growers Love GG4

GG4 became legendary because it combines:

• elite resin production
• loud terpene expression
• strong hybrid effects
• vigorous growth
• proven cultivation history

Even years after release, it continues to compete with modern cultivars because of its unique balance of:

• frost
• potency
• aroma
• visual quality

Few cultivars have had the long-term impact GG4 has had on modern cannabis breeding and cultivation.

🌱 Pro Grower Notes

One of the biggest things to prepare for with GG4 is support management late in flower.

The combination of:

• stretch
• lateral branching
• heavy resin-covered flowers

can create significant branch weight.

Using trellis support early makes canopy management much easier later in bloom.

Many growers also report that extending flower slightly longer can increase chocolate and earthy terpene expression.

🧬 Why Clones Make GG4 Even Better

GG4 is famous as a clone-only cultivar.

Growing verified GG4 clones allows growers to preserve:

• terpene expression
• resin production
• structure consistency
• flowering behavior

This removes the variability that often comes with seed phenotypes.

Explore the Clone Collection to grow cultivation-ready clones selected for indoor performance, resin production, and stable growth behavior.

Consistency preserves legendary genetics.

🌱 Final Thoughts

Gorilla Glue #4 remains one of the most iconic cannabis cultivars ever released for a reason.

Its combination of:

• heavy frost
• loud diesel terpenes
• balanced hybrid effects
• proven indoor performance

continues to make it a favorite among growers and consumers alike.

For cultivators chasing resin-heavy flower with true legendary status, GG4 still delivers.
