Genetics & Growth Traits

Massassin Auto combines Monster Mass x Mazar x CMC Big Bud Auto, creating a sturdy autoflower with compact growth, robust branching and strong flower development. Monster Mass brings density and yield potential, Mazar adds classic Afghani influence and heavy resin appeal, while CMC Big Bud Auto gives the strain its autoflowering speed and chunky flower structure.

This autoflowering variety is listed as an Indica/Sativa hybrid with a harvest time of around 65–70 days. Plants are described as low and bushy, reaching approximately 0.6–0.8m in height, with dark green narrow leaves and strong, dank flowers. Yields are stated at around 550g/m² indoors and 80–150g per plant outdoors, making Massassin Auto a compact but productive option with solid Critical Mass Collective performance.

Expect medium-density buds on strong branches, finished with emerald-green tones, flashes of light turquoise, orange and white hairs, and a shimmering crystal coat. Sticky to the touch and full of aroma, Massassin Auto has that proper resin-rich bag appeal that makes classic hashy genetics so satisfying.

Aroma and Flavour

Massassin Auto has a bold, old-school aroma led by skunk funk, deep Afghani hash and sweet oily undertones. Subtle citrus notes lift the profile, adding a fresh edge to the heavier earthy and musky base.

The flavour is strong, hashy and smooth, with a rich Afghani-style foundation. Expect deep skunk and hash on the inhale, followed by soft musky sweetness, a touch of vanilla and gentle orange zest on the exhale. It is dank, rounded and full-bodied, making it a standout for fans of hash-flavoured autoflowering cannabis seeds and traditional skunky hybrids.

Effects

Massassin Auto is described as potently relaxing, with an almost medicinal-style calm. The effect begins quickly with a euphoric lift, bringing a happy and comfortable mood before gradually settling into deeper physical relaxation.

In smaller amounts, the effect can remain versatile and easy-going, while heavier sessions lean more into a sleepy, soothing and full-body wind-down. It is a great fit for collectors interested in relaxing autoflowering seeds with a smooth euphoric start and a calming, body-led finish.
