20 Guage by Afterthought Autos
Ruderalis × Indica × Sativa
20 Guage is an autoflowering hybrid cannabis variety developed by Afterthought Autos, a breeder focused on resilient and practical genetics. Engineered as a three-way cross of ruderalis, indica, and sativa, it automatically transitions to flowering based on age, offering a user-friendly experience for growers and consumers alike.
Appearance
This autoflowering strain typically grows to a compact size, reaching heights between 60-100 cm indoors. It often develops a prominent central cola with several supporting branches, which can be further balanced with early low-stress training. The buds are characterized by tidy spears with moderate spacing between calyxes, abundant trichome coverage, and can sometimes display faint purplish hues near the leaf edges under specific temperature conditions.
Aroma & Flavor
The aroma profile of 20 Guage is a balanced blend featuring earthy, citrus, and subtly peppery notes, often with initial impressions of warm herbs and pine over a sweet, earthy base. A bright top note reminiscent of lemon or orange rind is common, with underlying spice notes that can emerge as the flowers cure. When consumed, it presents a gentle sweet-earth baseline with lemon zest on the inhale and a peppery, resinous finish on the exhale.
Effects
Fans generally describe 20 Guage as a versatile, all-day strain offering approachable potency. While the source notes mention it can be lively rather than sedating, it is also associated with providing physical comfort and a functional, elevated mood. The effects are considered user-friendly and balanced, suitable for various times of day.
Terpenes & Cannabinoids
While specific cannabinoid percentages are not detailed beyond the general THC range of 12-14% and CBD below 1%, the terpene profile is inferred to include myrcene, limonene, caryophyllene, pinene, and linalool. These contribute to the strain's earthy, herbal, citrus, peppery, and floral aromatic and flavor characteristics. Total terpene content in well-cultivated plants often ranges from 1.2% to 2.0%.
Growing
20 Guage is recognized for its speed, compact structure, and resilience, making it suitable for novice and intermediate growers, especially in less-than-ideal climates or small indoor spaces. As an autoflower, it requires no special light cycle management to initiate flowering, with a predictable seed-to-harvest timeline. It performs well under common autoflower light schedules like 18/6 or 20/4 and responds favorably to gentle training techniques.
Origins & Lineage
Developed by Afterthought Autos, 20 Guage is a three-way hybrid cross combining ruderalis, indica, and sativa genetics. The ruderalis component provides the autoflowering trait and contributes to a more compact and hardy plant structure. The indica and sativa genetics are integrated to offer a balanced effect profile, enhancing both physical comfort and mental tone, while also contributing to terpene complexity and yield.
