Magnum Autoflower packs a bright, sativa-leaning character into a fast, easygoing grow. Expect lively citrus-sweet flavor, resin-coated buds, and an upbeat effect that suits creative projects and daytime plans. With a compact autoflower cycle and generous yield potential, it brings plenty of reward to a short season.
Its exact lineage remains unknown, with ruderalis genetics supporting automatic flowering and a reported 60% sativa, 40% indica balance. Our breeders selected Magnum Auto for robust growth and reliable performance across a range of setups. Plants can reach around 1.5 m, with a mostly sativa structure and sturdy branching.
Citrus leads the aroma, followed by a spicy edge and smooth sweetness. The finished buds develop dense, resin-rich surfaces with a frosty coat of trichomes. That lively blend carries through on the inhale, making each session crisp, fragrant, and flavorful.
At 12–14% THC, Magnum Auto offers a gentler potency profile with an energetic, uplifting feel. Expect a cheerful mood, a creative spark, and a touch of physical ease. Its balanced character makes it an inviting option for growers seeking a lighter, sociable experience.
Caryophyllene and myrcene shape the variety’s terpene profile, adding warm spice and earthy depth to its citrus-sweet notes. These aromatic qualities make Magnum Auto a natural fit for relaxed evenings, creative sessions, or sharing with friends. Its resin production also makes the buds appealing for concentrate projects.
These autoflowering seeds move from germination to harvest in approximately 8–10 weeks. They flower automatically, so growers do not need to change the light schedule to trigger bloom. Magnum Auto is rated beginner-friendly, and every Grassfarmer order comes with our germination guarantee.
Give seedlings a quality, well-draining medium such as coco or a suitable soil blend, and keep moisture consistent without waterlogging the roots. Autoflowers benefit from a gentle start and steady care throughout their short cycle. Indoors, an 18/6 or 20/4 light schedule can support vigorous growth.
Magnum Auto grows well indoors or outdoors in temperate conditions. Choose a sunny outdoor location or provide strong, consistent lighting indoors. Keep airflow moving through the canopy, monitor humidity, and check regularly for pests. Its hardy growth and manageable structure make it a versatile choice for different grow spaces.
With attentive care, indoor plants can produce around 350–400 g/m², while outdoor plants may yield 400–600 g each. The quick 8–10-week life cycle offers a rapid route to harvest, and its all-season harvest rating adds flexibility for outdoor planning. Dense, resinous buds reward a steady, well-managed grow.
