Magnum Autoflowering Seeds

Magnum Autoflowering Seeds are a vigorous autoflowering hybrid associated with Skunk × Haze × autoflowering ancestry. Unlike many compact autos, Magnum generally develops a taller, more open frame with long side branches, good internodal spacing, and elongated resinous flowers. Its larger automatic growth habit makes it useful for growers who want more canopy development without moving to a full-season photoperiod plant.

• Lineage: Skunk-family × Haze-family genetics × autoflowering ancestry
• Growth type: Sativa-leaning autoflower
• Plant structure: Medium-tall to tall for an auto, with long branches and an open canopy
• Stretch: Moderate to high
• Indoor seed-to-harvest: Typically about 10–11 weeks from sprouting
• Outdoor seed-to-harvest: Typically about 10–12 weeks from sprouting; harvest depends on sowing date
• Flower structure: Elongated, moderately dense flowers with good resin coverage
• Resin production: Moderate to high
• Colour: Bright to medium green with orange pistils and a frosted finish
• Aroma: Citrus, herbs, earth, spice, and light Haze sweetness
• Best suited for: Growers wanting a larger autoflower with strong branching and a longer, more open canopy

Magnum Auto generally benefits from adequate root space because its natural vigor can produce a substantially larger plant than many compact autos. Gentle low-stress training can help spread the long side branches, while heavy repeated pruning is less useful because the automatic vegetative window is limited.

Indoors, a practical full-cycle target is approximately 70–77 days from sprouting. Flowers typically form along the main stem and upper branches, becoming increasingly resinous through the final weeks.

Outdoors, timing is determined by planting date rather than autumn day length. Under favourable conditions, growers should plan on roughly 10–12 weeks from sprouting. This makes the cultivar useful for warm-season outdoor cycles where a photoperiod Haze would finish too late.

The aromatic profile commonly combines bright citrus with herbal, earthy, spicy, and lightly sweet Haze notes. Magnum Autoflowering Seeds are best suited to growers looking for a vigorous, taller auto with a roughly ten-to-eleven-week life cycle and a more open sativa-style structure.
