Grandaddy Black brings midnight color, thick resin, and deep Indica calm to your garden. Expect dense, crystal-coated buds, rich sweetness, and a powerful 19%–23% THC range. This feminized variety pairs striking looks with rewarding yields.
Our breeders created Grandaddy Black by crossing Black Domina ’98 with Grandaddy Purple. The result leans 90% Indica and 10% Sativa, drawing on a celebrated heritage that includes Purple Urkle, Big Bud, Afghan, Northern Lights, Hash Plant, and Ortega.
Earthy depth meets ripe fruit and sweet notes in every aromatic layer. As the buds mature, their rich fragrance builds alongside a heavy coating of resin, giving the harvest an especially appealing finish.
The experience blends relaxation with an energetic, upbeat lift and a spark of arousal. Its strong body-centered character makes Grandaddy Black a popular choice for evening sessions and winding down after a demanding day.
Terpineol, Linalool, and Valencene shape this strain’s distinctive terpene profile. Its soothing character appeals to those seeking a calmer evening or a restful nighttime routine. Many customers also choose it for personal wellness routines involving discomfort, stiffness, or sleep.
These feminized seeds produce female plants, and Grassfarmer guarantees germination. Grandaddy Black is rated suitable for beginners, with sturdy, compact growth and a manageable structure. Give seedlings a quality, well-draining medium such as coco, peat, or a suitable soil blend.
Build healthy early growth with steady light, clean airflow, and consistent care. Keep daytime temperatures around 68–80°F, with nights slightly cooler. Maintain relative humidity near 55%–60% during vegetative growth, then lower it as flowering progresses.
Grandaddy Black reaches about 4.92 feet (1.5 m) and grows well indoors or outdoors in warm conditions. Provide ample sunlight outside, or use a spacious indoor setup with good ventilation. ScrOG training can help create an even canopy and bring lower flower sites into the light.
Flowering takes approximately 8–10 weeks. Expect dense, resin-rich buds that can show deep purple, nearly black hues. Indoor yields can reach 500–600 g/m² (1.64–1.97 oz/ft²); outdoor plants can produce around 450 g (15.87 oz) each, with harvest typically in October.
