Blue Monster lives up to its name with hulking, resin-caked flowers that lean heavily indica yet keep a whisper of sativa lift. Bred by Goldenseed, this UK original braids together G13, Blueberry, Northern Lights #5, and a Mexican landrace, producing a compact, branchy plant that can flash blue-violet hues as temperatures dip late in bloom. The nose opens with ripe blueberry and mixed-berry sweetness from its Blueberry heritage, layered over earthy-diesel accents; flavors follow suit, finishing clean on the palate. Limonene, caryophyllene, and pinene headline the terpene ensemble, amplifying a deeply relaxing body calm while preserving a bright top note. Typically testing around 15–29% THC with up to 1% CBD, its effect profile settles the body, coaxes appetite, and eases the mind into a contented, sleepy mood. Indoors, Blue Monster flowers in roughly 56–63 days; outdoors it wraps by early autumn. Expect high yields — often about 12 oz per well-grown plant outside — with dense, frosty colas that trim easily. Fans prize its balanced demeanor: a happy, soothing unwind backed by classic berry-forward aroma, credible lineage, and the sturdy, forgiving cultivation traits you would expect from G13 and Northern Lights crossed with a connoisseur-grade Blueberry.
