Magnum Cookies Auto by Silver River Seeds
Sativa-dominant line × Cannabis ruderalis
Magnum Cookies Auto is a sativa-leaning autoflowering hybrid from Silver River Seeds, combining ruderalis genetics with sativa traits for a fast-finishing, energetic cultivar. It is designed for growers seeking a compact plant with dessert-like aromas and flavors that mature quickly without photoperiod adjustments.
Appearance
This cultivar typically develops dense, conical flower structures with noticeable trichome coverage. The bracts range from emerald to lime green, with pistils maturing from ivory to shades of tangerine and amber. Under cooler temperatures late in flowering, some phenotypes may exhibit faint purpling along the sugar leaves.
The plants generally maintain a manageable height, often between 70-110 cm indoors, with a structure that responds moderately to low-stress training. The bud formation is dense but not overly compact, and the sugar leaves are typically modest, contributing to a favorable dry flower-to-leaf ratio.
Aroma & Flavor
The aroma profile is characterized by sweet, baked-dough notes layered with warm spice and a citrus-pepper lift. As the buds mature, undertones of vanilla and brown sugar may emerge, complemented by herbal or green tea hints. When agitated, the aroma can become more pronounced with peppery and woody components.
On the palate, Magnum Cookies Auto often presents a confectionary sweetness upfront, followed by a peppered citrus sensation on the exhale. Flavors can include notes reminiscent of sweet cream, orange zest, and vanilla, with a clean herbal finish after curing.
Effects
Magnum Cookies Auto is noted for providing energetic effects, aligning with its sativa-leaning genetics. The experience is generally uplifting and can contribute to a more driven state.
Terpenes & Cannabinoids
While specific cannabinoid percentages are not detailed, this strain typically falls within a THC range of 15-25% and contains less than 1% CBD. The terpene profile is often inferred to include Myrcene, Limonene, Caryophyllene, and Humulene, contributing to its characteristic aroma and flavor notes.
Growing
As an autoflowering hybrid, Magnum Cookies Auto transitions from seed to harvest without requiring changes in light cycles, typically completing its life cycle in 75 to 90 days. It is suitable for both indoor and outdoor cultivation, with reported indoor yields ranging from 400-550 g/m² and outdoor yields of 60-150 g per plant under optimal conditions.
The plant's ruderalis heritage contributes to its hardiness and compact stature, making it accessible for growers with limited space. It benefits from consistent light, nutrition, and airflow, with moderate odor output requiring ventilation management, especially during the later stages of flowering.
