Blueberry Kush is an indica-dominant feminized cross of Blueberry and OG Kush, with a sweet blueberry, berry and earthy flavour. Leafly classes it as an indica; one seller’s spec sheet lists it as an indica-dominant hybrid, and another puts it at about 90% indica. It flowers in about 8 to 10 weeks indoors, and Leafly’s grow data rates it difficult to grow.

History & lineage

Blueberry Kush brings together Blueberry and OG Kush. Blueberry was originally bred by DJ Short, and its history goes back to the late 1970s, when he was working with exotic landrace strains, and it reached the Dutch market in 1998. OG Kush’s origins are less certain. Leafly reports it was first cultivated in Florida in the early 1990s from a cross that supposedly involved Chemdawg, Lemon Thai and a Hindu Kush plant. Who first crossed the two into Blueberry Kush isn’t recorded: Leafly credits no breeder.

Both parents have Cup records. Blueberry, one of its parents, won the 2000 High Times Cannabis Cup (the Noon coffeeshop’s entry), and Dutch Passion’s Blueberry won that year’s Indica Cup. OG Kush, its other parent, won the Hybrid Cup at the 2011 High Times Medical Cannabis Cup in San Francisco (D & M Compassion Center’s entry).

Aroma & flavour

Expect blueberry first, then berry, sweet and earthy notes. For Blueberry Kush as a strain, Leafly users most often report blueberry, berry, sweet and earthy flavours, in that order, with pungent and flowery further down, and one seller’s spec sheet lists its taste as earthy, fruity and sweet. Leafly’s lab data lists myrcene as its most abundant terpene, followed by caryophyllene and pinene; our guide to cannabis terpenes explains what each one adds.

Effects, as users report them

Most reportedRelaxed · Happy · Sleepy · Euphoric · Uplifted
Downsides reportedDry mouth · Dry eyes · Dizzy · Headache · Paranoid

These are Leafly users’ reports for Blueberry Kush as a strain, most common first, and some also report feeling hungry. The most commonly reported downsides are dry mouth and dry eyes, followed by dizziness and headaches, and some users report paranoia or anxiety. Seed sellers list THC from 19% to 24%, and Leafly’s strain data gives 18%, so if you are new to cannabis, start with a small amount; effects vary with the person and the dose.

Growing Blueberry Kush

Blueberry Kush is a feminized photoperiod plant: it keeps growing leaves until the light drops to 12 hours a day indoors, or until the days shorten in late summer outdoors. Seed sellers give a flowering time of about 8 to 10 weeks indoors, and Leafly’s grow data about 63 days. Outdoors in the Northern Hemisphere, one seller’s sheet puts the harvest in late October, so check that the window comes before your first fall frost.

This is not a beginner’s plant. Leafly’s grow data rates it difficult to grow, and one seller calls it hard to dial in. Leafly lists it as a medium-height plant, which one seller’s spec sheet puts at about 150–245 cm (5–8 ft), so plan for the stretch in early flower. Leafly’s grow data puts its average yield at high; expect around 400–500 g/m² (1.3–1.6 oz/ft²) indoors and about 500 g (18 oz) per plant outdoors. The buds are dense, so keep humidity down and airflow up in late flower to protect them from bud rot, and judge when to harvest by the trichomes rather than the calendar.

Sweet, Relaxing, and Reliable

10 August 2025

Blueberry Kush fem grew beautifully—compact structure, heavy buds, and a strong blueberry aroma that got sweeter during cure. Smoke is smooth and flavorful, with a deep body stone that melts away stress. Perfect evening strain. Zero complaints, just pure chill.

Great Taste

This strain is one of the most flavorful strain i have ever grown. The high is on mark and very relaxing.

Big, Loud, and Knockout Strong

31 July 2025

Fat Bastard Auto is an absolute beast—short and chunky, with huge resin-packed buds that smell like skunky citrus mixed with sweet earth. One joint and I was done—full-body melt, couch-lock, the whole package. If you want a heavy-hitting auto, this one’s it. Big yield, big flavor, big chill.

Tommy

Berry Smooth, Hits Deep

31 July 2025

Blueberry Kush is straight-up flavor therapy. Grew low and bushy with fat, resinous buds that smelled like sweet berries and fresh earth. Smooth, tasty smoke with a slow-building body high that melted my stress away. Perfect for nighttime chillouts. Tastes as good as it looks.
