SR71 Feminized by Purple City Genetics

Information on SR71

SR71 is a feminized photoperiod variety created by Purple City Genetics within their American Graffiti SS24 collection. Compact, resinous and easy to grow, this indica-dominant hybrid has captured the interest of European growers due to its extraordinarily intense terpene profile and long-lasting relaxing effect.

Genetics: an elite Californian lineage

SR71 is born from the cross between Oaksterdam OG and Street Guru. The latter is in turn the combination of Gush Mints and Oreoz (Oooze from 3rd Coast Genetics), which places SR71 within a modern genetic line of high resin potential. The result is an indica-dominant plant that concentrates the best of its parents: dense structure, exceptional trichome production and an aromatic profile that the breeder itself defines as «real gas».

Growing behavior: accessible and highly productive

Indoors, SR71 completes its flowering in 8-9 weeks with an estimated production of 500-650 g/m². Its compact structure, with short internodes and tight buds, makes it ideal for high-density grows. Purple City Genetics describes it as an «easy to grow» variety, and its terpenes are already very pronounced from mid-flowering cycle. Under cooler nighttime temperatures, the plant can express an attractive purple coloration in its leaves and buds. Its high trichome production also makes it an outstanding candidate for extraction production.

Outdoors, harvest falls between late September and early October, with plants that can yield up to 800 g/plant and medium-high resistance to fungi and pests. Its ease of management and robustness make it especially suitable for both beginner growers and those looking to maximize their outdoor production without technical complications.

Aromas, flavors and effects

SR71's olfactory profile is direct and unmistakable: intense diesel and gasoline at the forefront, over an earthy and sweet base with hints of dough and biscotti. On the palate, the flavor maintains that line of gas and earth, completed with rubbery notes and a slightly sweet aftertaste that rounds out the consumption experience.

The effect is markedly indica: potent, physical and long-lasting. At moderate doses, SR71 induces a deep physical relaxation accompanied by a calm and clear mental state. Its very high THC level places it among the varieties with the greatest physical impact in the current catalog, which is why it is especially recommended for nighttime consumption or rest moments, being a solid choice for those who prioritize physical relief over mental stimulation.
