Double Glock (Cannabis Strain)

Double Glock is a pure indica cultivar selected from stable Afghan landrace stock. Typically testing between 18% and 22% THC, this variety is characterized by its dense, resin-rich flowers and a deep, earthy hash aroma highlighted by a dark berry edge. The plant shows a stocky, broad-leafed growth profile, making it a classic representation of ancestral mountain indicas suited for evening relaxation.

Known for its slow vegetative pace but explosive late-stage flower development, this cultivar develops solid, spear colas covered in sticky, greasy resin. It serves as a reliable genetic baseline for growers seeking pure, unhybridized indica traits. The heavy physical profile and high resin yield make it a preferred choice for traditional solventless extraction.

Quick Facts

Scientific & Botanical Overview

Botanically, Double Glock shows classic pure indica morphology, characterized by exceptionally broad fan leaves, thick woody stems, and tight internodal spacing. The vegetative cycle requires patience, as the plant focuses its energy on building a dense lateral structure rather than vertical stretch. This growth habit results in a low, bushy profile that is highly wind-resistant and structurally stable.

During the generative phase, the nodal sites compress further, giving rise to tightly clustered, hard-bract flowers. The calyx-to-leaf ratio is moderate, requiring targeted defoliation to ensure adequate light penetration and airflow through the dense inner canopy. The dense bracts resist physical damage but can trap moisture if environmental controls are not optimized.

Anthocyanin accumulation is common when night temperatures drop late in the flowering cycle, tinting the deep green foliage with dark purple and near-black hues. The trichome heads are large and capitate-stalked, producing a dense, greasy resin layer that is highly sought after by traditional hash makers. This high concentration of resin glands acts as a natural defense mechanism inherited from its high-altitude origins.

Effects & Use-Cases (Reported)

Commonly reported effects: Deep physical relaxation, heavy sedation, and a calming mental ease that slows down racing thoughts.

Use-case context: This cultivar is best reserved for late-evening or nighttime use when no further physical activity is planned. Its heavy physical footprint makes it highly suitable for wind-down routines and quiet, stationary activities.

Note: Due to its pure indica heritage, users commonly report a heavy couch-lock sensation that can transition quickly into deep, uninterrupted sleep. Beginners should approach this cultivar with caution due to its rapid physical onset.

Aroma & Flavors

Aroma: Earthy hash, spicy pine, and a subtle dark berry edge that becomes more pronounced as the flowers dry and cure.

Flavor: Sweet, toasted herbal notes mixed with a classic damp-earth kush base, leaving a lingering peppery finish on the exhale.

Terpene associations:
Myrcene, caryophyllene, and limonene dominate the volatile profile, driving the heavy, musk-forward bouquet and contributing to the physical relaxation associated with the cultivar.

Tested Cannabinoid & Terpene Ranges

Note: Cannabinoid and terpene levels are highly phenotype-dependent and heavily influenced by cultivation methods, curing protocols, and environmental conditions.

Cultivation Notes

• Humidity: Keep relative humidity under 45% during late flower to protect the dense, compact colas from moisture retention and mold.
• Nutrition: Requires a robust feeding schedule during the late vegetative phase to support its thick-stemmed structure, but feeds lighter during mid-to-late flower.
• Training: Responds well to early topping and low-stress training (LST) to open up the tight interior canopy and improve light penetration.
• Harvest: Best harvested when trichomes are mostly milky with a generous sprinkling of amber, typically around day 60 to 65.
• Phenotype management: Expect minimal stretch once flowering is induced, usually doubling in size at most; plan vegetative times accordingly to achieve desired final heights.

Grower Notes (Week-by-Week Snapshot)

• Weeks 1–3 (Vegetative & Early Flower): Focus on building a strong root system and structural training. The plant will grow slowly and stay low to the ground with massive fan leaves.
• Weeks 4–6 (Mid-Flower): Internodes compress tightly as the first flower clusters form. Perform a thorough defoliation of lower fan leaves to maximize airflow and light penetration to lower nodes.
• Weeks 7–9 (Late Flower & Ripening): Resin production peaks, coating the buds in a wet, greasy frost. Reduce humidity levels and lower night temperatures to encourage dark color expressions and preserve volatile terpenes.
• Post-Harvest (Dry & Cure): A slow, 10-to-14-day dry at 60°F (15°C) and 60% relative humidity is essential to lock in the earthy, hash-like aroma before a minimum four-week jar cure.

Genetic Lineage

Double Glock is a stable selection derived from pure indica landrace genetics sourced from the rugged valleys of Afghanistan. The breeders worked to stabilize this line over multiple generations, selecting specifically for vigor, resin production, and the classic physical traits of ancestral hash plants. This rigorous selection process preserved the rugged resilience of the landrace while adapting it for modern indoor environments.

By avoiding hybridization with sativa-leaning cultivars, the genetic lineage remains purely indica. This preservation of heritage ensures that the classic, heavy-bodied traits of traditional Afghan domesticates are consistently expressed across different phenotypes, offering a reliable genetic tool for both preservationists and contemporary breeders.

Research Insights

Analytical testing of pure Afghan lineages like Double Glock frequently reveals a high concentration of sesquiterpenes such as caryophyllene alongside monoterpenes like myrcene. This specific chemical profile is studied for its contribution to the physical “body stone” associated with traditional hashish. The absence of sativa hybridization keeps the cannabinoid profile focused almost entirely on THC and minor compounds like CBG, with negligible CBD content.

From a breeding perspective, the stability of this homozygous pure indica line makes it an excellent tool for introducing structural rigidity and dense flower traits into modern polyhybrids. Researchers and breeders value its predictable growth patterns and high resistance to common environmental stressors, which can be passed down reliably to offspring in crossbreeding programs.

Frequently Asked Questions

Is Double Glock suitable for outdoor cultivation?

Yes, it performs exceptionally well outdoors in dry, warm climates where harvest can be completed before late-autumn rains, usually by early October. Its dense bud structure makes it susceptible to rot in humid or rainy outdoor environments.

How much does Double Glock stretch during flowering?

This cultivar has a very controlled stretch, typically increasing in height by only 50% to 100% after transitioning to a 12/12 light cycle. Growers should ensure the plants reach their desired size in veg before flipping.

What is the ideal vegetative time for Double Glock?

Because of its slow vegetative growth rate, growers often extend the veg period by one to two weeks compared to faster-growing hybrids to achieve optimal plant size and canopy development before flowering.

What does Double Glock smell like?

It features a deep, earthy aroma dominated by spicy hash, pine, and a sweet, dark berry undertone that becomes more pronounced after a proper cure.
