747 by Dr Greenthumb
Unknown
747 is a sativa-dominant hybrid bred by Dr. Greenthumb, recognized for its vigorous growth and uplifting cerebral effects. This cultivar offers a crisp, citrus-forward aroma and a clean finish, distinguishing it from heavier strains. Its name suggests power and performance, aligning with its energetic profile and impressive plant structure.
Appearance
747 buds typically exhibit a refined sativa structure, appearing as elongated spears or conical clusters with medium density. The flowers are characterized by favorable calyx-to-leaf ratios, simplifying manicuring and enhancing their cured appearance. Expect lime to forest-green hues, sometimes with subtle lavender flecks, especially in cooler finishing temperatures. Bright tangerine pistils contrast with a heavy frosting of capitate-stalked trichomes, which mature from clear to cloudy and amber.
Aroma & Flavor
Upon opening, 747 presents a bright aroma dominated by sweet citrus and pine sap, complemented by a clean floral top note. Subtle hints of tropical fruit and green apple skin may also be detected, alongside a faint peppery spice. When ground, the aroma can intensify, sometimes revealing eucalyptus or minty facets. The flavor profile on inhale is lively, featuring citrus and pine with a light floral sweetness and a crisp, clean finish.
Effects
747 is generally regarded for its uplifting and cerebral effects, making it suitable for daytime use. Consumers report a lift in energy and mood, promoting clear-headed productivity and creativity. Unlike more sedating strains, 747 is noted for its bright, clean finish rather than a heavy, myrcene-dominant experience.
Terpenes & Cannabinoids
While specific lab results vary, 747 typically tests with THC content around 20% and CBD levels below 1%. The terpene profile is often characterized by notes of Myrcene, Limonene, Caryophyllene, Linalool, Pinene, Terpinolene, Ocimene, and Eucalyptol, contributing to its citrus, pine, and floral aromatic qualities. Total terpene content in well-grown examples can range from 1.5% to 3.5%.
Growing
As a sativa-dominant cultivar, 747 tends to exhibit tall internodes and pronounced stretch during early bloom, often experiencing a 1.5x to 2.5x increase in height after the light flip. Canopy management is crucial, especially in indoor environments. Indoor yields can commonly range from 450–600 g/m², while outdoor plants in suitable climates may exceed 1.5 kg per plant. The flowering period typically lasts between 9–11 weeks.
Origins & Lineage
Bred by Dr. Greenthumb, a breeder known for vigorous and garden-ready genetics, 747 is a sativa-dominant hybrid. The precise genetic lineage has not been publicly disclosed by the breeder. However, its phenotypic expression, including tall stature and energizing effects, suggests a hybridized sativa background, possibly incorporating influences from classic sativa families like Haze, Thai, or Colombian lines, refined with modern hybrids for improved yield and a practical flowering window.
