Genetics & Growth Traits

Monster Mass Auto combines Monster Mass x Afghan Monolith, creating a mostly Indica autoflower with rich old-school influence and a strong, resin-heavy flower style. Monster Mass brings density, vigour and that classic Critical Mass Collective structure, while Afghan Monolith adds vintage Afghan depth, earthy hash character and a powerful physical effect.

This autoflowering variety is listed with a seed-to-harvest time of around 65–70 days. Yields are stated at approximately 400–450g/m² indoors and around 150–170g per plant outdoors, giving Monster Mass Auto solid production potential in a fast auto format.

Expect dense, highly perfumed nuggets with vibrant green, gold, black and plum tones. Sticky silver trichomes and fiery orange-gold hairs complete the look, giving the flowers a rich, colourful and seriously classic appearance.

Aroma and Flavour

Monster Mass Auto has a pungent, earthy aroma built around old-school skunk, strong hash and deep Afghan-style funk. A slightly fruity edge and incense-like perfume add extra complexity, giving the scent a nostalgic 80s hippy trail feel with a rich, lingering presence.

The flavour is pure hash heaven. Expect intense sweetness, earthy skunk depth and a long-lasting hashy finish that coats the tongue and cheeks. It is bold, smooth and full-bodied, making it a standout pick for fans of hash-flavoured autoflowering cannabis seeds and classic Indica-style terpene profiles.

Effects

Monster Mass Auto is described as physically powerful, deeply sedating and potentially couch-locking. The effect starts with a warming buzz around the head and neck before quickly building into a heavier full-body calm.

Its mostly Indica character makes it ideal for evening-style downtime, switching off and settling into a slower, more relaxed pace. Smooth, strong and body-focused, Monster Mass Auto delivers a classic sedative experience with plenty of old-school weight.
