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.

Sehr kräftig, absolut für Anfänger geeignet. Wächst extrem kompakt und ist ohne Training mit unheimlich vielen Blüten übersäht. Die Meisten werden nicht extrem riesig. Duftet extrem gut und schmeckt noch viel besser.

Super happy with the outcome 💪👍🌱😍 I found it to be perfect for after work strain, when you done for the day, i call it "just me time" although it does not give you "the couch effect" also perfect for sharinf with a loved one 🧘‍♀️ This is perfect strain for new growers as it does not require much maintenance and will forgive you small errors. Thank you Zamnesia you are 10/10! 🌱🌱🌱

A very nice tasty take on a classic strain. Being from the uk I know my cheese and blue cheese varieties and though this isn't what I would call a proper uk cheese strain.. it is better then most European alternatives I've come across. The blue monster has a distinct flavour to it that's different from their blueberry but it comes close I would liken it to a very fruity skunk strain that is a very enjoyable and tasty strain that leaves you with a very fruity and menthol aftertaste.

Was a very pleasant strain to grow. Would definitely grow this one again! Smells and tastes of citrus fruits, blueberry and cheesecake. A nicely balanced hybrid throughout the day. Just enough indica to keep you relaxed, but sativa enough to be invigorating and energizing. Great old school stuff in a modern strain.

Out of 5 seeds I managed to get 3 of them through the veg and onto flowering they have been a great plant to do LST and defoliation on they are more on the sativa side with growing tall and not bushy was able to open them all up nicely budz were small and not compact and spread out I only gave it 8stars because of the yield out of 2 I ended up with 4oz but otherwise it’s a good strain to start out with

First up a big thanks to Zamnesia for your support, awesome breeder always recommend 🍀🐱 Strong strain, nothing to complain, it has a great bushy growth, I accidentally topped it at the beginning in week three, but it was patched up with armor tape and quickly grew back together agains

She was a pleasure to grow and took everything I threw at her in stride. She was topped, fim'd super-cropped, shaken and endured 35°c heat wave. The past couple weeks she had that diesel smell however the past couple days a more sour smell emerged, especially while cutting the colas off.

Blue Monster is reliable like a Swiss clockwork. Flowering started exactly at start of 5th week, and exactly 9 weeks from seed to harvest as described on the seedbanks page (9-10w). The smell is strong, sweet, and fruity. Letting it dry and cure now. Nice relaxing.

Average rating but I think the strain is better and I did something wrong. The scent and the freeze soo incredible but the flowers have not inflated me much I think because of an exaggerated wind in the vegetative phase. A beautiful evening plant, however to be redone

This strain is one of the most famous hybrids of the last few years we have tried it in different sauces but this seems to us one of the best. He has grown very well, highly recommended the top regisce bebe and you are at the end of the really nice buds. Very relaxing in the evening.
