Appearance and Structure

Auto M8 typically exhibits a manageable stature, reaching heights between 70 and 110 cm indoors, making it suitable for smaller cultivation spaces like tents. Its structure is generally robust, benefiting from the ruderalis influence which can enhance hardiness, especially when grown outdoors in temperate climates. The plant is noted for elongated floral clusters and a high calyx-to-leaf ratio.

Aroma and Flavor Profile

This strain presents an aromatic profile often described as herbaceous and citrusy, with distinct notes of lime. Consumers can expect a lingering zest on the palate, often accompanied by undertones of pine or mint. The flavor is generally smooth on the initial inhale, contributing to its appeal.

Cannabinoid and Terpene Content

Auto M8 typically tests between 15% and 25% THC, with CBD levels below 1%. Its terpene profile is characterized by a constellation including myrcene, limonene, caryophyllene, terpinolene, and ocimene. Total terpene content in well-cultivated samples can range from 1.5% to 2.5% by dry weight.

Effects and Experience

Users report that Auto M8 delivers rapid-onset effects, often peaking within 30-45 minutes and lasting for 2-3 hours. The experience is primarily cerebral and energetic, aligning with its sativa-dominant heritage. It is associated with a clear, uplifting headspace, making it suitable for daytime use.

Cultivation Characteristics

As an autoflower, Auto M8 is independent of light cycles for flowering, typically maturing from seed to harvest in 10–12 weeks. Indoor yields are often cited between 350–500 g/m², with potential for higher production under optimized conditions. Its ruderalis genetics contribute to its hardiness and manageable size, making it a practical choice for both novice and experienced growers.

Developed by Gea Seeds, Auto M8 is a hybrid of ruderalis and sativa genetics, originating from Spain's autoflower development scene in the mid-to-late 2010s.
