Black Runtz brings candy-sweet allure, striking resin production, and deep, soothing effects to one standout feminized seed. With THC listed at 30–32% and a rich, layered aroma, this indica-leaning hybrid delivers a bold experience from its first sweet notes to its lingering calm.
Our breeders created Black Runtz from Black Diamond Sherbet x Runtz, combining two indica-leaning hybrids in a balanced 55% indica / 45% sativa profile. Known as the “dark twin” of original Runtz, this celebrated variety traces its roots to Burnaby, British Columbia, where it emerged in 2017.
Expect a vivid blend of earthy fruit, pine, sour zest, and warm spice. Dark grape and tropical-citrus hints brighten the sweet, candy-like core, while a fizzy finish adds a lively twist. The dense buds shine with a heavy coat of resin-rich trichomes.
Black Runtz pairs a strong, relaxing body high with an uplifting, euphoric mental buzz. The experience can feel creative, energetic, and deeply calming, making it a popular pick for winding down, easing everyday stress, and settling in for a restful evening. Its high potency suits experienced consumers.
Myrcene lends an earthy, fruity depth associated with physical ease. Alpha-pinene brings a crisp pine character and a clear, fresh edge, while caryophyllene adds peppery warmth. Linalool rounds out the profile. Together, these terpenes make Black Runtz especially appealing for fans of relaxing, flavor-forward flower and resin-rich extracts.
These feminized seeds grow into female plants, helping focus your garden on flower production. Black Runtz is suitable for beginners and experienced growers alike, with an 8–9 week flowering period. Germination is guaranteed by Grassfarmer, so you can start your grow with added confidence.
Give seedlings steady warmth, gentle light, and a well-draining medium such as coco coir, peat, or a perlite blend. Build a healthy root zone before increasing nutrients, then adjust feeding as plants move through vegetative growth and flowering. Indoor growers can use a ScrOG setup to guide an even canopy and improve light coverage.
Plants reach around 4.9 feet (1.5 m) and adapt to indoor or outdoor gardens. Maintain good airflow and stay alert to pests throughout the grow. Aim for daytime temperatures around 68–80°F, with cooler nights, and lower humidity as flowering progresses. Warm temperate and Mediterranean conditions suit this variety particularly well.
Plan for harvest after 8–9 weeks of flowering. Outdoor plants in the Northern Hemisphere are typically ready around October. Expect medium yields of approximately 400–450 g/m² indoors or 500–550 g per plant outdoors when conditions and care are on point. Dense, trichome-coated flowers deliver the strain’s signature aroma and excellent resin potential.
