Gorilla Glue #4 S1 (Feminized Seeds)

Lineage: Gorilla Glue #4 × Gorilla Glue #4 (S1 Selfed Line)

A Selfed Line That Intensifies the Iconic Resin Giant

Gorilla Glue #4 S1 represents a refined, tightened expression of one of the most recognizable resin-forward cultivars ever created. By selfing the original GG4, this line captures the essence of its parent—raw adhesive-style resin output, dense bud formation, and unmistakable structural power—while pushing it toward greater uniformity and predictability.

From early veg, you’ll notice the defining GG4 traits: rugged stems, broad leaves, and a steady, durable rhythm that signals a plant bred for production. The S1 process condenses these characteristics, creating a seed line where phenotypes land within a narrower, more consistent range. This stability makes Gorilla Glue #4 S1 easier to plan for, easier to scale, and far more reliable across varied environments.

Aroma & Terpene Profile — Pine Resin, Earthy Cocoa, and Sharp Herbal Depth

The aroma of Gorilla Glue #4 S1 opens boldly with warm pine resin and an earthy foundation reminiscent of fresh forest floor. As the canopy matures, deeper notes begin to surface—soft cocoa, faint nuttiness, and a subtle herbal sharpness that stays true to the original line’s rugged character.

Mid-flower brings richer expression: the resinous pine becomes more pronounced, the earthy layer gains dimension, and the cocoa undertone folds in smoothly. It’s a scent that feels grounded and unmistakably classic—thick, layered, and substantial without drifting into overpowering territory.

After curing, everything integrates into a polished, well-rounded bouquet. Expect a clean pine top note, warm earth beneath it, and a hint of woody spice that lingers softly. It’s a timeless aromatic profile that experienced growers identify instantly.

How It Grows — Rugged, Reliable, and Strong-Willed

Vegetative Structure & Canopy Development

Gorilla Glue #4 S1 shows early vigor and strength. Leaves are broad, deep green, and slightly waxy, a clear sign of its robust metabolism. The central stem thickens rapidly, and lateral branches develop evenly, giving growers a simple, cooperative architecture to work with.

Internodal spacing stays medium-tight, allowing for natural stacking while still leaving good airflow. The plant responds exceptionally well to topping, LST, mainlining, and trellising, making it suitable for both low-height grows and larger-scale production rooms.

Flowering Behavior & Resin Surge

Once flower sets in, Gorilla Glue #4 S1 quickly reveals why the original became a legend. Resin production starts early—often by week three—and increases aggressively at a consistent pace. By the late weeks, buds appear drenched in a thick, glossy coat that makes the cultivar instantly recognizable.

Stretch is moderate, typically around 1.5x, and the plant maintains strong structure throughout the cycle. Indoors, Gorilla Glue #4 S1 generally finishes in 8–9 weeks. Outdoors, harvest tends to land from late September through mid-October depending on climate.

Yields & Visual Appeal — Chunky Buds With Heavy Frost and Bold Texture

Bud Formation & Appearance

The S1 generation intensifies the parent line’s signature bud structure: chunky, dense clusters with thick calyx buildup and heavy resin layering. Colors range from olive greens to dark forest tones, accented by bright orange pistils woven through the frost.

Expect:

• Dense, weighty buds

• Significant resin coverage from early flower

• Strong calyx stacking

• Excellent commercial and boutique visual appeal

• Consistency across most phenotypes

Production Output

Gorilla Glue #4 S1 reliably delivers above-average yields, especially in dialed-in environments. The combination of dense bud formation and heavy resin makes it particularly appealing for growers who prioritize aromatic oil production and extraction-friendly material.

Why Grow Gorilla Glue #4 S1

This S1 refinement strengthens everything growers appreciate about the original Gorilla Glue #4: its rugged structure, its remarkable resin output, its earthy-pine aromatic signature, and its consistent performance across a variety of setups. With tighter uniformity and improved predictability, the S1 version becomes even more grower-friendly while preserving the bold identity that made GG4 famous.

For those seeking a feminized seed line with legacy character, immense resin density, and proven reliability, Gorilla Glue #4 S1 remains one of the most dependable choices available.
