Strain Description: Auto Monster Mass expertly translates the potency and production power of its photoperiod ancestor into a faster, easier-to-manage format. THC levels average 18–20%, delivering a long-lasting full-body stone that melts tension, boosts appetite and often sends users into deep, restful sleep. Growers may encounter three distinct phenotypes: neon green, subtly purple and an exceptionally rare “eerie blue” variant with sweeter floral tones. Regardless of expression, yields are huge, and branches frequently droop under the weight of swollen, resin-soaked buds.


Growing Information: Indoors, Auto Monster Mass responds exceptionally well to SCROG training, allowing growers to expose multiple bud sites along its thick lateral branches. Outdoors, it remains resilient, thriving when provided with strong light and stable feeding schedules. Plants reach 60–140 cm and complete their life cycle in approximately 70–80 days from seed. Late flower trichome inspection is recommended, as resin production becomes increasingly heavy and sticky toward harvest.


Flavour and Aromas: The aroma profile maintains the nostalgic funk of the original Monster Mass line, blending musky skunk and earthy sweetness with dark fruit undertones. On the palate, expect deep kush and pungent skunk, followed by blackberry and sweet cola candy nuances. The exhale delivers hashy warmth, trailing into a light citrus tang. Terpenes such as myrcene, limonene and caryophyllene reinforce its relaxing and flavour-rich signature.


Lineage: Monster Mass contributes colossal yields, heavy sedation and pristine visual appeal, while CMC Big Bud Auto introduces rapid autoflowering traits, enhanced density and increased production speed. Together, they form a reliable powerhouse suitable for both novices and experienced cultivators.


Summary: Auto Monster Mass is a high-impact autoflower built for growers seeking massive production, unforgettable aroma and a deeply relaxing, full-bodied effect. With enormous yields, rare colour morphs and flavour complexity, this cultivar earns its name at every stage—from seed to harvest to final toke.
