Jtr is an indica-leaning cultivar recognized for its potent THC content and uplifting psychoactivity. It is often sought after for its clarity and focus, making it a popular choice for daytime consumers and creatives.
Appearance
Jtr plants typically present with medium-tall stature and elongated branches. The leaves are narrow and serrated, indicative of their sativa influence. Mature colas develop as spears with significant calyx swelling, often exhibiting lime green to chartreuse coloration contrasted by vibrant orange pistils. Some phenos may display faint violet hues on sugar leaves under specific conditions. A notable characteristic is the dense trichome coverage, giving the buds a frosted, sticky appearance.
Aroma & Flavor

Underlying scents can include herbal and floral undertones, contributing to a complex bouquet. The flavor mirrors the aroma, offering a bright and zesty experience with hints of citrus, candy, and a subtle herbal finish.
Effects
Jtr is known for delivering a fast-acting and intensely uplifting head high, characterized by mental clarity and focus. Consumers often report feeling energetic and creative, making it suitable for daytime use. While not typically sedating, it is advised to use with caution in higher doses, as it can be quite potent.
Terpenes & Cannabinoids
This cultivar typically tests high in THC, ranging from 15-25%, with minimal CBD content (less than 1%). The terpene profile is often dominated by terpinolene and limonene, which contribute to its citrusy aroma and energetic effects. Other contributing terpenes may include beta-myrcene, beta-caryophyllene, and alpha-pinene.
Growing
Jtr is generally considered a moderate-difficulty strain to cultivate, often finishing its flowering cycle in approximately 8 to 9 weeks. It exhibits sativa-leaning growth patterns, including significant stretch after the light cycle flip. The plants benefit from training techniques to manage height and promote optimal canopy development. Jtr is noted for producing heavy resin glands, making it attractive for extraction.
Origins & Lineage
Jtr, also known as Jack the Ripper, was developed by the TGA Genetics collective, with contributions from the late Subcool. It is a cross between Jack's Cleaner and Space Queen. This lineage combines the citrus-forward aromatics of Jack's Cleaner with the vigorous growth and psychoactive clarity associated with Space Queen, which itself has roots in Romulan and Cinderella 99.
