Grape Killer 99 brings a bright, creative charge to the late afternoon. This feminized, sativa-leaning hybrid pairs a happy, focused headspace with a relaxed finish, wrapped in dense, resin-rich flowers and a bold grape-inspired flavor profile.

Our breeders created Grape Killer 99 by crossing Killer Grape with Cinderella 99. The result is a balanced-leaning hybrid with 60% sativa and 40% indica genetics, built for energetic, uplifting character and vigorous growth.

Expect a vivid mix of fruity sweetness, hashish depth, spicy accents, and a sugary finish. Its aromatic buds develop a frosty coat of trichomes, giving the flowers striking visual appeal and strong potential for flavorful extracts.

With THC levels of 15%–20%, Grape Killer 99 delivers a cheerful, clear-minded lift with focused energy and gentle relaxation. It suits creative sessions, social plans, or a mood-brightening reset after a long day.

Its terpene profile features Humulene, Alpha-Pinene, Beta-Pinene, Caryophyllene, Limonene, Linalool, and Myrcene. The blend complements the strain’s sweet, spicy aroma and makes Grape Killer 99 a compelling choice for growers who value aromatic flower and resin production. Effects and experiences vary from person to person.

These feminized seeds are designed to produce female plants, helping growers plan a consistent crop. The variety is listed as beginner-friendly, and germination is guaranteed when you follow the included guidance and applicable terms.

Give seedlings a clean start with quality soil or a well-prepared coco or peat mix, steady moisture, and gentle light. Build strong early growth with attentive watering and balanced nutrition, increasing feed gradually as plants develop.

Plants reach around 3.94 ft (1.2 m) and show a sativa-influenced structure. Indoors, a ScrOG setup can help spread the canopy and expose lower growth to light. Maintain good airflow, monitor humidity, and keep plants free from pests throughout the cycle.

Flowering takes about 8–10 weeks. Indoor growers can expect 400–500 g/m², while outdoor plants may produce around 600 g each in suitable conditions. In temperate climates, outdoor harvest typically arrives in October. Give the plant consistent sunshine and well-drained soil to support healthy flowering.
