The 2019 Cannabis Strain: Where Landrace Heritage Meets Hybrid Vigor
Built from Galileo and Arava landrace genetics, this line sits between classic feminized seeds and true F1 hybrids, with strong growth and layered terpenes.
Contents:
At Royal Queen Seeds, we’re proud to introduce a next-generation variety: The 2019, a cultivar that closes the gap between classic feminized lines and true F1 hybrids.
Why “The 2019”?
The name comes from the internal selection code we used during development, the moment this line clearly set itself apart from the rest.
Over four years, we developed and refined The 2019 with a clear focus on genetic expression, stability, and overall plant performance. The result is a feminized cultivar that delivers a level of consistency, vigor, and performance that moves closer to true F1 hybrid standards.
Meet The 2019.

A Four-Year Breeding Program Focused on Performance
At Royal Queen Seeds, we use F1 hybrid methodology alongside traditional cannabis breeding techniques. The 2019 is the outcome of an F1 hybrid development program designed to create a new generation of high-potency photoperiod cultivars that show genuine hybrid vigor.
The genetic pool comes from Levantine and West Asian landrace genetics, selected for resilience, quality, and overall performance. Across more than three years of successive trials and selections, we identified four especially promising hybrid candidates that moved into the final evaluation.
Among those candidates, R2-2019 (The 2019) quickly stood out as the clear leader. It outperformed the other lines in vigor, plant structure, and cannabinoid potential, reflecting the core traits we set out to capture in this program.
In the final evaluation, R2-2019 showed strong hybrid vigor across different environments, with a large plant structure, high potency potential, robust plant health, and a 100% germination rate. These results placed it clearly above the typical range of a standard feminized seed line.
Genetic Development and Hybrid Vigor
A key part of the development process involved S3 and S4 selfing, a breeding method in which plants are self-pollinated over successive generations to create inbred lines and stabilize desirable traits. This allowed us to lock in key characteristics before hybridization.
When these inbred lines are crossed, the resulting F1 generation expresses strong hybrid vigor, with high levels of consistency and performance from plant to plant.
A Word on Classification and Transparency
We hold our F1 hybrid designation to a strict standard, especially when it comes to plant-to-plant uniformity. After large-scale external trials in Q3 and Q4 2025 with Innexo and within the CfC consortium in the Netherlands, R2-2019 delivered excellent vigor, plant health, and productivity.
However, while the line showed strong and reliable performance, its level of homogeneity did not fully meet the high uniformity threshold we require for official F1 designation.
We could have lowered the bar. We didn’t.
We’re releasing R2-2019 as an advanced feminized seed line, with full transparency about its genetic position. It performs well above the typical feminized category, reflecting the advanced breeding work behind it.
It sits in the space between classic stabilized lines and fully uniform F1 hybrids.
In practice, growers will still notice clear hybrid-driven traits: robust growth, a large plant structure, high potency potential, and strong overall performance.
Genetic Foundation: Galileo x Arava Landrace
At the core of R2-2019 is a combination of refined modern genetics and rare regional landrace diversity. The Arava landrace component comes from West Asian material with a long history of adaptation, resilience, and environmental stability, shaped over generations in challenging climates.
This foundation is paired with Galileo genetics, which contribute structure and potency, while the landrace side brings aromatic complexity and raw vitality.
In R2-2019, this combination produces large, vigorous plants with a layered terpene profile led by chemical and fuel-forward notes, balanced by fruity, sweet-and-sour undertones.
What Growers Can Expect From The 2019
The breeding work behind The 2019 results in a cultivar that is genuinely rewarding to grow, with predictable behavior across setups and a sensory profile that holds your attention from veg through cure. Here’s what to expect across cultivation, flavor, and effect.
Growing The 2019: Indoor and Outdoor Performance
With a 65% sativa and 35% indica balance, The 2019 grows with energetic vigor, a solid frame, and enough control to perform well in different setups. Indoors, plants usually reach 3–4 ft and can produce 18–21 oz/yd² under good conditions, with a flowering time of 9–10 weeks (60–65 days). Outdoors, it has more room to stretch and can reach up to 6 ft, with yields in the range of 23–26 oz per plant and a harvest window in late October. In both environments, this strain stands out for its dependable structure and strong, repeatable performance.
Flavor Profile: Citrus Sharpness Meets Fruity Complexity
The terpene profile is led by limonene, which gives The 2019 a bright citrus edge layered over a distinctive chemical, fuel-forward backbone. That sharp, almost solvent-like opening is rounded out by fruity, sweet-and-sour notes and a deeper herbal undercurrent, creating a flavor that feels complex and full-bodied without becoming harsh. Supporting terpenes such as β-caryophyllene, humulene, pinene, and myrcene add extra texture, bringing subtle spice, earthiness, and freshness into the mix.
Potency and Effects of The 2019
With potency levels around 25% and relatively low CBD, The 2019 sits firmly in the high-potency category. The experience is often described as uplifting, creative, and motivating at first, making it a strong choice for moments when you want a clear, active mindset. Alongside that mental energy, there is also a steady layer of physical relaxation that softens the edges without tipping into an overly heavy effect.
The 2019 Sits Between Tradition and Innovation
The 2019 stands out for the depth of breeding behind it, combining strong vigor, reliable performance, and a complex, carefully curated terpene profile. It emerged as the clear standout in a demanding selection process, a reminder that even in structured breeding, nature still finds ways to surprise you.
