Black Magic Auto by Mavericks Genetics

Black Magic Auto is one of the darkest-looking autoflowers in the Mavericks Genetics range. This Indica-dominant plant produces dense lilac and reddish buds that can turn almost black under a heavy frost of trichomes, paired with a spicy, sweet and fruity aroma. Mavericks rates it at around 25% THC (±2%) and about 3.2% total terpenes, putting it among the most aromatic autos in the lineup.

The plant stays compact and manageable, and the color shift in late bloom makes it a standout in any tent. Resin production is generous, giving the flowers a sticky, high-end finish that holds up well in the jar.

As an autoflower, Black Magic Auto needs no switch to 12/12. Keep it under 18/6 or 20/4 the whole way. Mavericks lists 8–9 weeks of flowering, with yields up to 600 g/m² (1.97 oz/ft²) indoors and around 300 g/plant (10.6 oz/plant) outdoors.

Black Magic Auto Lineage

Mavericks lists Black Magic Auto as Blackberry Kush crossed with a Ruderalis line. Blackberry Kush is known for its dark, berry-tinted flowers and heavy Indica structure, which explains the deep colors and squat frame here. The Ruderalis share brings automatic flowering.

The breeder ratio is 75% Indica, 20% Sativa and 5% Ruderalis. Expect short internodes, wide leaves and chunky colas rather than a tall, stretchy plant.

Aroma, Flavor and Effect

The bouquet is spicy, sweet and fruity, with deeper earthy tones underneath. Dark berry sweetness sits up front while a peppery spice builds as the buds are broken apart. At around 3.2% total terpenes, this is a pungent plant in late flower.

The smoke is smooth and rich: fruit and sugar on the inhale, spice and earth on the exhale, with a finish that lingers.

Mavericks describes the effect as potent and deeply relaxing, suited to evening use. With roughly 25% THC, the body feel is heavy and calming, so it fits slow nights in more than active days.

Growing Black Magic Auto Indoors and Outdoors

Indoors, sow straight into a final container of 11–15 L (3–4 gal) and keep the lights on 18/6 or 20/4. Begin light LST in week two or three to widen the canopy, and avoid topping or heavy defoliation, since autos have limited time to recover. Cooler nights during the last weeks can help bring out the lilac and red tones. Keep humidity moderate as the dense buds fill out.

Outdoors, Black Magic Auto suits a sunny spot in a large container or bed. Mavericks lists around 300 g/plant (10.6 oz/plant). Its short life cycle lets growers in shorter seasons finish before fall rain, and warmer regions can run back-to-back crops.

For harvest, check trichomes with a loupe and cut when most are cloudy with some amber for the fullest body effect.
