Summary / Suitability
Chemnesia F4 unites two cornerstones of modern breeding: Chem 91 and Chem D cuts—with Amnesia Core, an elite haze-type mother known for clarity and speed. The F4 generation consolidates four years of refinement into a stable, vigorous hybrid showing both Chem family resin density and Amnesia’s electric uplift. Bred in Jamaica in 2023 and selected from 150 plants in Colombia in 2025, it was developed for growers seeking high potency and a dense, fuel-forward profile without excessive stretch.

Genetic Background
This line descends from the original Chemnesia series (A Chem D × Chem 91 base hybridized to Amnesia Core) worked to F4 through selective inbreeding. Chem 91 contributes sharp diesel aroma and stacked flower formation, while Chem D adds depth and heavy resin production. Amnesia Core injects clarity, incense, and a smoother terpene transition. The combination creates a compact, dense flower structure with an exceptionally rich fuel and pine nose.

Plant Characteristics
Plants exhibit short internodes and sturdy stems, typically finishing between 90 and 110 days of flowering. Primary phenotypes include two vigorous medium-tall forms with strong apical growth and thick 5-blade leaves, and shorter, bushier phenos with 3-blade formations and dense bud sites. The line shows uniform branching, early resin onset, and tight, resin-frosted colas forming from week 3 onward. Coloration ranges from deep green to slate tones with amber trichome accumulation by late flower.

Flower & Aroma Profile
Aromas combine classic Chem fuel and rubber notes with Amnesia’s incense and wood tones. On rub, stems release sharp pine and sweet earthy gas that translates directly to the finished flower. Cured buds emit a layered scent of fuel, lemon oil, and resinous incense. Flavors mirror this balance — a dense, creamy smoke with diesel on the inhale and spiced citrus and earth on the exhale.

Growing Tips (Indoor & Outdoor)
Indoor: Responds well to topping and light defoliation. Maintain consistent feeding and strong airflow to support dense flowers. Low stretch makes it suitable for multi-top canopies or SOG layouts.
Outdoor / Greenhouse: Thrives in warm, tropical conditions with good root space. Prefers balanced organic nutrition and a dry finish period to maximize resin density and terpene expression. Finishes by mid-to-late season in most Colombian highland zones.

Effects & Potency
A powerful hybrid effect merging Chem’s intense euphoria with Amnesia’s energetic clarity. The experience begins with a strong rush of mental focus and uplift before settling into a calm body stoned state. Long-lasting and potent, an estimated in the 22–26% THC depending on phenotype and cultivation. Ideal for experienced consumers seeking flavor and potency in equal measure.
