Cowboy JON OG by Mavericks Genetics

Cowboy JON OG is a premium feminized photoperiod created through a collaboration between Mavericks Genetics and Cowboy Jon, a well-known extraction specialist. Built on Marathon OG x Banana Frosting, it was selected for both flower quality and resin performance, delivering fiery red-toned buds, a tropical passion fruit nose and THC around 27% (±2%).

The flowers are dense and well structured, with red tones that stand out sharply against deep green. A thick resin layer gives the buds a frosted, sticky finish that looks as good in the jar as it does on a hash bench.

Mavericks lists 9–10 weeks of flowering and an outdoor harvest from late September into early October. Yields reach around 350 g/m² (1.15 oz/ft²) indoors and around 600 g/plant (21.2 oz/plant) outdoors, with a balanced 50/50 Indica/Sativa makeup.

Cowboy JON OG Lineage

Mavericks describes Cowboy JON OG as a cross of two standout OG selections, listed on the spec sheet as Marathon OG x Banana Frosting. Marathon OG supplies the OG backbone, structure and resin, while Banana Frosting adds sweet fruit and frosty trichome coverage.

The project was shaped with extraction in mind. Cowboy Jon’s input steered the selection toward plants that wash and press well, without giving up flower quality.

Aroma, Flavor and Effect

The aroma is vibrant and tropical: passion fruit up front, followed by ripe berries and sweet pineapple. With about 2.8% total terpenes, the fruit notes are intense and well defined.

The flavor is smooth, sweet and distinctly tropical, with a long fruity finish. That clarity of flavor carries into rosin and ice water hash, which is part of what this cultivar was bred for.

Thanks to its 50/50 build, Mavericks describes an uplifting, euphoric head buzz that settles into a relaxing body feel, keeping the experience balanced. At around 27% THC, it adapts to different times of day depending on the amount consumed.

Growing Cowboy JON OG Indoors and Outdoors

Indoors, top early and train the canopy flat with LST or a SCROG net, then flip to 12/12 once the space is mostly filled. The 9–10 week bloom rewards patience: the last weeks bring the red tones and the full terpene load. Keep humidity moderate and airflow steady to protect the resin-heavy colas. Mavericks lists around 350 g/m² (1.15 oz/ft²).

Outdoors, plant in full sun with plenty of root space. Mavericks lists around 600 g/plant (21.2 oz/plant), with harvest from late September to early October. The strong structure helps the plant carry its colas through late-season wind.

For extractors, the breeder highlights rosin, ice water hash and other solventless methods. Harvesting at peak cloudy trichomes and freezing fresh material preserves the tropical terpenes for washing.
