Blue OG #4
An indica-dominant masterpiece crossing Blue Moonshine with OG Kush—engineered for flavor and aesthetic perfection
What is Blue OG #4?
Blue OG #4 represents the pinnacle of classic hybrid breeding from G13 Labs. By carefully selecting the fourth phenotype of their Blue OG project, breeders captured the ideal balance between the legendary Blue Moonshine and a quintessential OG Kush. This genetic marriage results in a plant that carries the best traits of both worlds: the compact structure and berry sweetness of the Blue lineage, and the fuel-heavy, high-potency kick of the OG side.
The result is a stout, productive plant that produces neon-green buds with deep purple hues. Blue OG #4 is celebrated not just for its effects, but for its stability and predictable growth patterns. Starting with a verified breeder cut ensures that you are getting the specific #4 selection known for its enhanced berry-gas aroma. This is a must-have for gardens focusing on top-shelf flower production and sensory complexity.
Terpene Profile
The Blue OG #4 terpene profile is a sophisticated blend of forest berries and high-octane fuel. The initial nose is dominated by sweet blueberry and ripe forest fruits, quickly followed by a heavy, chemical gas exhale. It is a terpene profile that stays on the palate long after the session has ended.
Growing Blue OG #4
Blue OG #4 is a dream for growers of all experience levels due to its manageable height and high resistance to pests. Unlike many OG crosses, this phenotype remains compact and stocky, making it perfect for SOG (Sea of Green) or space-limited indoor setups. Expect a modest stretch and a very fast flowering time, with most plants finishing in exactly 8 weeks.
Key Growing Tips
-
DefoliationHeavy leaf production means strategic defoliation in week 3 is vital for light penetration
-
Cold TempsLowering night temps in the final 2 weeks will bring out deep violet hues
-
NutrientsResponds best to a standard nutrient regimen; avoid over-feeding in late flower
-
TrainingDoes not require heavy support, but LST helps maximize the berry-rich side colas
Blue OG #4 is a high-performance flower strain. While its trichomes are plentiful, they are best appreciated as premium flower rather than extraction material to preserve the delicate berry terpene volatile oils.
Flower Quality & Bag Appeal
While some strains are bred for the wash, Blue OG #4 was bred for the connoisseur jar. The bag appeal is legendary, featuring incredibly dense, medium-sized flowers that look like they've been dipped in sugar. The contrast between the dark purple sugar leaves and the bright lime green calyxes makes for a stunning visual presentation.
The texture of the cured flower is sticky and resinous, requiring a grinder to properly break down. Because this is not a "washer" strain, the focus is entirely on the preservation of the flower's structural integrity and its intense aromatic profile. This is the flower you pull out when you want to impress with smell and sight alone.
Flower Characteristics
Blue OG #4 focuses its energy on producing high-density flowers with a massive concentration of surface-level trichomes. For the cultivator, this means a product that holds its weight well after the drying and curing process.
Effects & Experience
The experience of Blue OG #4 is characterized by a rapid onset of euphoria that quickly mellows into a deep, functional relaxation. It is less "couch-lock" than its OG Kush parent, thanks to the Blue Moonshine influence, making it an excellent choice for late afternoon or evening social sessions.
